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 βopen e-bookβ (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: β/some path/with spacesβ
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
Below are the options that are common to all conversion, followed by the options specific to every input and output format.
- --help, -hΒΆ
show this help message and exit
- --input-profileΒΆ
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-recipesΒΆ
List builtin recipe names. You can create an e-book from a builtin recipe like this: ebook-convert
"
Recipe Name.recipe"
output.epub
- --output-profileΒΆ
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
- --versionΒΆ
show program
'
s version number and exit
Look and FeelΒΆ
Options to control the look and feel of the output
- --asciiizeΒΆ
Transliterate Unicode characters to an ASCII representation. Use with care because this will replace Unicode characters with ASCII. For instance it will replace
"
PelΓ©"
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.
- --base-font-sizeΒΆ
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-justificationΒΆ
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-font-rescalingΒΆ
Disable all rescaling of font sizes.
- --embed-all-fontsΒΆ
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-font-familyΒΆ
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.
- --expand-cssΒΆ
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.
- --extra-cssΒΆ
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.
- --filter-cssΒΆ
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
- --font-size-mappingΒΆ
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-blank-lineΒΆ
Insert a blank line between paragraphs. Will not work if the source file does not use paragraphs (<p> or <div> tags).
- --insert-blank-line-sizeΒΆ
Set the height of the inserted blank lines (in em). The height of the lines between paragraphs will be twice the value set here.
- --keep-ligaturesΒΆ
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.
- --line-heightΒΆ
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.
- --linearize-tablesΒΆ
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.
- --margin-bottomΒΆ
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.
- --margin-leftΒΆ
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.
- --margin-rightΒΆ
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.
- --margin-topΒΆ
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.
- --minimum-line-heightΒΆ
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-paragraph-spacingΒΆ
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).
- --remove-paragraph-spacing-indent-sizeΒΆ
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.
- --smarten-punctuationΒΆ
Convert plain quotes, dashes and ellipsis to their typographically correct equivalents. For details, see https://daringfireball.net/projects/smartypants.
- --subset-embedded-fontsΒΆ
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.
- --transform-css-rulesΒΆ
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.
- --transform-html-rulesΒΆ
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.
- --unsmarten-punctuationΒΆ
Convert fancy quotes, dashes and ellipsis to their plain equivalents.
Heuristic ProcessingΒΆ
Modify the document text and structure using common patterns. Disabled by default. Use βenable-heuristics to enable. Individual actions can be disabled with the βdisable-* options.

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.
- --disable-renumber-headingsΒΆ
Looks for occurrences of sequential <h1> or <h2> tags. The tags are renumbered to prevent splitting in the middle of chapter headings.
- --disable-unwrap-linesΒΆ
Unwrap lines using punctuation and other formatting clues.
- --enable-heuristicsΒΆ
Enable heuristic processing. This option must be set for any heuristic processing to take place.
- --html-unwrap-factorΒΆ
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-breaksΒΆ
Replace scene breaks with the specified text. By default, the text from the input document is used.
Search and ReplaceΒΆ
Modify the document text and structure using user defined patterns.
- --search-replaceΒΆ

"
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-markΒΆ
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.
- --disable-remove-fake-marginsΒΆ
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.
- --insert-metadataΒΆ
Insert the book metadata at the start of the book. This is useful if your e-book reader does not support displaying/searching metadata directly.
- --page-breaks-beforeΒΆ

- --dont-split-on-page-breaksΒΆ
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.

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.
- --epub-toc-at-endΒΆ
Put the inserted inline Table of Contents at the end of the book instead of the start.

- --preserve-cover-aspect-ratioΒΆ
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.
