NAME

ebook-convert - ebook-convert

ebook-convert input_file output_file [options]


Convert an e-book from one format to another.

input_file is the input and output_file is the output. Both must be specified as the first two arguments to the command.

The output e-book format is guessed from the file extension of output_file. output_file can also be of the special format .EXT where EXT is the output file extension. In this case, the name of the output file is derived from the name of the input file. Note that the filenames must not start with a hyphen. Finally, if output_file has no extension, then it is treated as a folder and an "open e-book" (OEB) consisting of HTML files is written to that folder. These files are the files that would normally have been passed to the output plugin.

After specifying the input and output file you can customize the conversion by specifying various options. The available options depend on the input and output file types. To get help on them specify the input and output file and then use the -h option.

For full documentation of the conversion system see E-book conversion

Whenever you pass arguments to ebook-convert that have spaces in them, enclose the arguments in quotation marks. For example: "/some path/with spaces"

The options and default values for the options change depending on both the input and output formats, so you should always check with:

ebook-convert myfile.input_format myfile.output_format -h

Specify the input profile. The input profile gives the conversion system information on how to interpret various information in the input document. For example resolution dependent lengths (i.e. lengths in pixels). Choices are: cybookg3, cybook_opus, default, hanlinv3, hanlinv5, illiad, irexdr1000, irexdr800, kindle, msreader, mobipocket, nook, sony, sony300, sony900

List builtin recipe names. You can create an e-book from a builtin recipe like this: ebook-convert "Recipe Name.recipe" output.epub

Specify the output profile. The output profile tells the conversion system how to optimize the created document for the specified device. In some cases, an output profile can be used to optimize the output for a particular device, but this is rarely necessary. Choices are:cybookg3, cybook_opus, default, generic_eink, generic_eink_hd, generic_eink_large, hanlinv3, hanlinv5, illiad, ipad, ipad3, irexdr1000, irexdr800, jetbook5, kindle, kindle_dx, kindle_fire, kindle_oasis, kindle_pw, kindle_pw3, kindle_scribe, kindle_voyage, kobo, msreader, mobipocket, nook, nook_color, nook_hd_plus, pocketbook_inkpad3, pocketbook_lux, pocketbook_hd, pocketbook_900, pocketbook_pro_912, galaxy, sony, sony300, sony900, sony-landscape, sonyt3, tablet

LOOK AND FEEL

Options to control the look and feel of the output

Transliterate Unicode characters to an ASCII representation. Use with care because this will replace Unicode characters with ASCII. For instance it will replace "Pelé" with "Pele". Also, note that in cases where there are multiple representations of a character (characters shared by Chinese and Japanese for instance) the representation based on the current calibre interface language will be used.

The base font size in pts. All font sizes in the produced book will be rescaled based on this size. By choosing a larger size you can make the fonts in the output bigger and vice versa. By default, when the value is zero, the base font size is chosen based on the output profile you chose.

Change text justification. A value of "left" converts all justified text in the source to left aligned (i.e. unjustified) text. A value of "justify" converts all unjustified text to justified. A value of "original" (the default) does not change justification in the source file. Note that only some output formats support justification.

Disable all rescaling of font sizes.

Embed every font that is referenced in the input document but not already embedded. This will search your system for the fonts, and if found, they will be embedded. Embedding will only work if the format you are converting to supports embedded fonts, such as EPUB, AZW3, DOCX or PDF. Please ensure that you have the proper license for embedding the fonts used in this document.

Embed the specified font family into the book. This specifies the "base" font used for the book. If the input document specifies its own fonts, they may override this base font. You can use the filter style information option to remove fonts from the input document. Note that font embedding only works with some output formats, principally EPUB, AZW3 and DOCX.

By default, calibre will use the shorthand form for various CSS properties such as margin, padding, border, etc. This option will cause it to use the full expanded form instead. Note that CSS is always expanded when generating EPUB files with the output profile set to one of the Nook profiles as the Nook cannot handle shorthand CSS.

Either the path to a CSS stylesheet or raw CSS. This CSS will be appended to the style rules from the source file, so it can be used to override those rules.

A comma separated list of CSS properties that will be removed from all CSS style rules. This is useful if the presence of some style information prevents it from being overridden on your device. For example: font-family,color,margin-left,margin-right

Mapping from CSS font names to font sizes in pts. An example setting is 12,12,14,16,18,20,22,24. These are the mappings for the sizes xx-small to xx-large, with the final size being for huge fonts. The font rescaling algorithm uses these sizes to intelligently rescale fonts. The default is to use a mapping based on the output profile you chose.

Insert a blank line between paragraphs. Will not work if the source file does not use paragraphs (<p> or <div> tags).

Set the height of the inserted blank lines (in em). The height of the lines between paragraphs will be twice the value set here.

Preserve ligatures present in the input document. A ligature is a combined character of a pair of characters like ff, fi, fl et cetera. Most readers do not have support for ligatures in their default fonts, so they are unlikely to render correctly. By default, calibre will turn a ligature into the corresponding pair of normal characters. Note that ligatures here mean only unicode ligatures not ligatures created via CSS or font styles. This option will preserve them instead.

The line height in pts. Controls spacing between consecutive lines of text. Only applies to elements that do not define their own line height. In most cases, the minimum line height option is more useful. By default no line height manipulation is performed.

Some badly designed documents use tables to control the layout of text on the page. When converted these documents often have text that runs off the page and other artifacts. This option will extract the content from the tables and present it in a linear fashion.

Set the bottom margin in pts. Default is 5.0. Setting this to less than zero will cause no margin to be set (the margin setting in the original document will be preserved). Note: Page oriented formats such as PDF and DOCX have their own margin settings that take precedence.

Set the left margin in pts. Default is 5.0. Setting this to less than zero will cause no margin to be set (the margin setting in the original document will be preserved). Note: Page oriented formats such as PDF and DOCX have their own margin settings that take precedence.

Set the right margin in pts. Default is 5.0. Setting this to less than zero will cause no margin to be set (the margin setting in the original document will be preserved). Note: Page oriented formats such as PDF and DOCX have their own margin settings that take precedence.

Set the top margin in pts. Default is 5.0. Setting this to less than zero will cause no margin to be set (the margin setting in the original document will be preserved). Note: Page oriented formats such as PDF and DOCX have their own margin settings that take precedence.

The minimum line height, as a percentage of the element's calculated font size. calibre will ensure that every element has a line height of at least this setting, irrespective of what the input document specifies. Set to zero to disable. Default is 120%. Use this setting in preference to the direct line height specification, unless you know what you are doing. For example, you can achieve "double spaced" text by setting this to 240.

Remove spacing between paragraphs. Also sets an indent on paragraphs of 1.5em. Spacing removal will not work if the source file does not use paragraphs (<p> or <div> tags).

When calibre removes blank lines between paragraphs, it automatically sets a paragraph indent, to ensure that paragraphs can be easily distinguished. This option controls the width of that indent (in em). If you set this value negative, then the indent specified in the input document is used, that is, calibre does not change the indentation.

Convert plain quotes, dashes and ellipsis to their typographically correct equivalents. For details, see https://daringfireball.net/projects/smartypants.

Subset all embedded fonts. Every embedded font is reduced to contain only the glyphs used in this document. This decreases the size of the font files. Useful if you are embedding a particularly large font with lots of unused glyphs.

Path to a file containing rules to transform the CSS styles in this book. The easiest way to create such a file is to use the wizard for creating rules in the calibre GUI. Access it in the "Look & feel->Transform styles" section of the conversion dialog. Once you create the rules, you can use the "Export" button to save them to a file.

Path to a file containing rules to transform the HTML in this book. The easiest way to create such a file is to use the wizard for creating rules in the calibre GUI. Access it in the "Look & feel->Transform HTML" section of the conversion dialog. Once you create the rules, you can use the "Export" button to save them to a file.

Convert fancy quotes, dashes and ellipsis to their plain equivalents.

HEURISTIC PROCESSING

Modify the document text and structure using common patterns. Disabled by default. Use --enable-heuristics to enable. Individual actions can be disabled with the --disable-* options.

Analyze hyphenated words throughout the document. The document itself is used as a dictionary to determine whether hyphens should be retained or removed.

Remove empty paragraphs from the document when they exist between every other paragraph

Turn indentation created from multiple non-breaking space entities into CSS indents.

Left aligned scene break markers are center aligned. Replace soft scene breaks that use multiple blank lines with horizontal rules.

Look for common words and patterns that denote italics and italicize them.

Detect unformatted chapter headings and sub headings. Change them to h2 and h3 tags. This setting will not create a TOC, but can be used in conjunction with structure detection to create one.

Looks for occurrences of sequential <h1> or <h2> tags. The tags are renumbered to prevent splitting in the middle of chapter headings.

Unwrap lines using punctuation and other formatting clues.

Enable heuristic processing. This option must be set for any heuristic processing to take place.

Scale used to determine the length at which a line should be unwrapped. Valid values are a decimal between 0 and 1. The default is 0.4, just below the median line length. If only a few lines in the document require unwrapping this value should be reduced

Replace scene breaks with the specified text. By default, the text from the input document is used.

SEARCH AND REPLACE

Modify the document text and structure using user defined patterns.

Path to a file containing search and replace regular expressions. The file must contain alternating lines of regular expression followed by replacement pattern (which can be an empty line). The regular expression must be in the Python regex syntax and the file must be UTF-8 encoded.

Replacement to replace the text found with sr1-search.

Search pattern (regular expression) to be replaced with sr1-replace.

Replacement to replace the text found with sr2-search.

Search pattern (regular expression) to be replaced with sr2-replace.

Replacement to replace the text found with sr3-search.

Search pattern (regular expression) to be replaced with sr3-replace.

STRUCTURE DETECTION

Control auto-detection of document structure.

When an <img> tag has no alt attribute, check the associated image file for metadata that specifies alternate text, and use it to fill in the alt attribute. The alt attribute is used by screen readers for assisting the visually challenged.

An XPath expression to detect chapter titles. The default is to consider <h1> or <h2> tags that contain the words "chapter", "book", "section", "prologue", "epilogue" or "part" as chapter titles as well as any tags that have class="chapter". The expression used must evaluate to a list of elements. To disable chapter detection, use the expression "/". See the XPath Tutorial in the calibre User Manual for further help on using this feature.

--chapter-mark
Specify how to mark detected chapters. A value of "pagebreak" will insert page breaks before chapters. A value of "rule" will insert a line before chapters. A value of "none" will disable chapter marking and a value of "both" will use both page breaks and lines to mark chapters.

Some documents specify page margins by specifying a left and right margin on each individual paragraph. calibre will try to detect and remove these margins. Sometimes, this can cause the removal of margins that should not have been removed. In this case you can disable the removal.

Enigu librometadatumojn ĉe la teksto komencante libron. Utilas se la bitlibra aparato ne permesas montri/serĉi metadatumojn rekte.

An XPath expression. Page breaks are inserted before the specified elements. To disable use the expression: /

Use the cover detected from the source file in preference to the specified cover.

Remove the first image from the input e-book. Useful if the input document has a cover image that is not identified as a cover. In this case, if you set a cover in calibre, the output document will end up with two cover images if you do not specify this option.

An XPath expression to detect the location in the document at which to start reading. Some e-book reading programs (most prominently the Kindle) use this location as the position at which to open the book. See the XPath tutorial in the calibre User Manual for further help using this feature.

TABLE OF CONTENTS

Control the automatic generation of a Table of Contents. By default, if the source file has a Table of Contents, it will be used in preference to the automatically generated one.

When creating a TOC from links in the input document, allow duplicate entries, i.e. allow more than one entry with the same text, provided that they point to a different location.

XPath expression that specifies all tags that should be added to the Table of Contents at level one. If this is specified, it takes precedence over other forms of auto-detection. See the XPath Tutorial in the calibre User Manual for examples.

XPath expression that specifies all tags that should be added to the Table of Contents at level two. Each entry is added under the previous level one entry. See the XPath Tutorial in the calibre User Manual for examples.

XPath expression that specifies all tags that should be added to the Table of Contents at level three. Each entry is added under the previous level two entry. See the XPath Tutorial in the calibre User Manual for examples.

Maximum number of links to insert into the TOC. Set to 0 to disable. Default is: 50. Links are only added to the TOC if less than the threshold number of chapters were detected.

Don't add auto-detected chapters to the Table of Contents.

Remove entries from the Table of Contents whose titles match the specified regular expression. Matching entries and all their children are removed.

If fewer than this number of chapters is detected, then links are added to the Table of Contents. Default: 6

Normally, if the source file already has a Table of Contents, it is used in preference to the auto-generated one. With this option, the auto-generated one is always used.

METADATO

Normally, resources linked to by the HTML file or its children will only be allowed if they are in a sub-folder of the original HTML file. This option allows including local files from any location on your computer. This can be a security risk if you are converting untrusted HTML and expecting to distribute the result of the conversion.

Traverse links in HTML files breadth first. Normally, they are traversed depth first.

Normally this input plugin re-arranges all the input files into a standard folder hierarchy. Only use this option if you know what you are doing as it can result in various nasty side effects in the rest of the conversion pipeline.

Do not extract images from the document

Regular expression to remove lines at the bottom of a page. This only looks at the last line of a page and works only with the new PDF engine.

Skip everything to the specified number of pixels at the bottom of a page. Negative numbers mean auto-detect and remove footers, zero means do not remove footers and positive numbers mean remove footers that appear below that many pixels from the bottom of the page. Works only with the new PDF engine.

Paragraph structure to assume. The value of "off" is useful for formatted documents such as Markdown or Textile. Choices are: * auto: Try to auto detect paragraph type * block: Treat a blank line as a paragraph break * single: Assume every line is a paragraph * print: Assume every line starting with 2+ spaces or a tab starts a paragraph * unformatted: Most lines have hard line breaks, few/no blank lines or indents * off: Don't modify the paragraph structure

Normally extra spaces are condensed into a single space. With this option all spaces will be displayed.

Normally extra space at the beginning of lines is retained. With this option they will be removed.

AZW3 OUTPUT OPTIONS

Disable compression of the file contents.

Extract the contents of the generated AZW3 file to the specified folder. The contents of the folder are first deleted, so be careful.

When adding the Table of Contents to the book, add it at the start of the book instead of the end. Not recommended.

Don't add Table of Contents to the book. Useful if the book has its own table of contents.

When present, use author sort field as author.

DOCX OUTPUT OPTIONS

Custom size of the document. Use the form width x height, for example: 123x321 to specify the width and height (in pts). This overrides any specified page-size.

Do not insert the book cover as an image at the start of the document. If you use this option, the book cover will be discarded.

Do not insert the table of contents as a page at the start of the document.

The size of the bottom page margin, in pts. Default is 72pt. Overrides the common bottom page margin setting, unless set to zero.

The size of the left page margin, in pts. Default is 72pt. Overrides the common left page margin setting.

The size of the right page margin, in pts. Default is 72pt. Overrides the common right page margin setting, unless set to zero.

EPUB OUTPUT OPTIONS

Turn off splitting at page breaks. Normally, input files are automatically split at every page break into two files. This gives an output e-book that can be parsed faster and with less resources. However, splitting is slow and if your source file contains a very large number of page breaks, you should turn off splitting on page breaks.

This option is needed only if you intend to use the EPUB with FBReaderJ. It will flatten the file system inside the EPUB, putting all files into the top level.

Insert an inline Table of Contents that will appear as part of the main book content.

The maximum image size (width x height). A value of none means use the screen size from the output profile. A value of profile means no maximum size is specified. For example, a value of 100x200 will cause all images to be resized so that their width is no more than 100 pixels and their height is no more than 200 pixels. Note that this only affects the size of the actual image files themselves. Any given image may be rendered at a different size depending on the styling applied to it in the document.

Put the inserted inline Table of Contents at the end of the book instead of the start.

The version of the EPUB file to generate. EPUB 2 is the most widely compatible, only use EPUB 3 if you know you actually need it.

Extract the contents of the generated EPUB file to the specified folder. The contents of the folder are first deleted, so be careful.

Split all HTML files larger than this size (in KB). This is necessary as most EPUB readers cannot handle large file sizes. The default of 260KB is the size required for Adobe Digital Editions. Set to 0 to disable size based splitting.

Normally, if the input file has no cover and you don't specify one, a default cover is generated with the title, authors, etc. This option disables the generation of this cover.

Do not use SVG for the book cover. Use this option if your EPUB is going to be used on a device that does not support SVG, like the iPhone or the JetBook Lite. Without this option, such devices will display the cover as a blank page.

When using an SVG cover, this option will cause the cover to scale to cover the available screen area, but still preserve its aspect ratio (ratio of width to height). That means there may be white borders at the sides or top and bottom of the image, but the image will never be distorted. Without this option the image may be slightly distorted, but there will be no borders.

MOBI OUTPUT OPTIONS

Disable compression of the file contents.

Extract the contents of the generated MOBI file to the specified folder. The contents of the folder are first deleted, so be careful.

By default calibre generates MOBI files that contain the old MOBI 6 format. This format is compatible with all devices. However, by changing this setting, you can tell calibre to generate MOBI files that contain both MOBI 6 and the new KF8 format, or only the new KF8 format. KF8 has more features than MOBI 6, but only works with newer Kindles. Allowed values: old, both, new

Ignore margins in the input document. If False, then the MOBI output plugin will try to convert margins specified in the input document, otherwise it will ignore them.

By default calibre converts all images to JPEG format in the output MOBI file. This is for maximum compatibility as some older MOBI viewers have problems with other image formats. This option tells calibre not to do this. Useful if your document contains lots of GIF/PNG images that become very large when converted to JPEG.

When adding the Table of Contents to the book, add it at the start of the book instead of the end. Not recommended.

Don't add Table of Contents to the book. Useful if the book has its own table of contents.

Tag for MOBI files to be marked as personal documents. This option has no effect on the conversion. It is used only when sending MOBI files to a device. If the file being sent has the specified tag, it will be marked as a personal document when sent to the Kindle.

When present, use author sort field as author.

The default font size for monospaced text (in pixels)

Do not insert the book cover as an image at the start of the document. If you use this option, the book cover will be discarded.

Shift the text horizontally by the specified offset (in pts). On odd numbered pages, it is shifted to the right and on even numbered pages to the left. Use negative numbers for the opposite effect. Note that this setting is ignored on pages where the margins are smaller than the specified offset. Shifting is done by setting the PDF CropBox, not all software respects the CropBox.

The size of the bottom page margin, in pts. Default is 72pt. Overrides the common bottom page margin setting, unless set to zero.

The size of the left page margin, in pts. Default is 72pt. Overrides the common left page margin setting.
