pdf2djvu accepts the following options:
Documenttype,filenames-o, --output=output-djvu-file
Generate a bundled multi-page document. Write the file into output-djvu-file instead of standard
output.
-i, --indirect=index-djvu-file
Generate an indirect multi-page document. Use index-djvu-file as the index file name; put the
component files into the same directory. The directory must exist and be writable.
--page-id-template=template
Specifies the naming scheme for page identifiers. Consult the “TEMPLATE LANGUAGE” section for the
template language description.
The default template is “p{page:04*}.djvu”.
For portability reasons, page identifiers:
• must consist only of lowercase ASCII letters, digits, _, +, - and dot,
• cannot start with a +, - or a dot,
• cannot contain two consecutive dots,
• must end with the .djvu or the .djv extension.
--page-id-prefix=prefix
Equivalent to “--page-id-template=prefix{page:04*}.djvu”.
--page-title-template=template
Specifies the template for page titles. Consult the “TEMPLATE LANGUAGE” section for the template
language description.
The default template is “{label}”.
--no-page-titles
Don't set page titles.
Resolution,pagesize-d, --dpi=resolution
Specifies the desired resolution to resolution dots per inch. The default is 300 dpi. The allowed
range is: 72 ≤ resolution ≤ 6000.
--media-box
Use MediaBox to determine page size. CropBox is used by default.
--page-size=widthxheight
Specifies the preferred page size to width pixels × height pixels. The actual page size may be
altered in order to respect aspect ratio and DjVu limitations on resolution. (This option takes
precedence over -d/--dpi.)
--guess-dpi
Try to guess native resolution by inspecting embedded images. Use with care.
Imagequality--bg-slices=n+...+n, --bg-slices=n,...,n
Specifies the encoding quality of the IW44 background layer. This option is similar to the -slice
option of c44. Consult the c44(1) manual page for details. The default is 72+11+10+10.
--bg-subsample=n
Specifies the background subsampling ratio. The default is 3. Valid values are integers between 1 and
12, inclusive.
--fg-colors=default
Try to preserve all the foreground layer colors. This is the default.
--fg-colors=web
Reduce foreground layer colors to the web palette (216 colors). This option is not recommended.
--fg-colors=n
Use GraphicsMagick to reduce number of distinct colors in the foreground layer to n. Valid values are
integers between 1 and 4080. This option is not recommended.
--fg-colors=black
Discard any color information from the foreground layer.
--monochrome
Render pages as monochrome bitmaps. With this option, --bg-... and --fg-... options are not
respected.
--loss-level=n
Specifies the aggressiveness of the lossy compression. The default is 0 (lossless). Valid values are
integers between 0 and 200, inclusive. This option is similar to the -losslevel option of cjb2;
consult the cjb2(1) manual page for details. This option can be used only if the --monochrome option
is also enabled.
--lossy
Synonym for --loss-level=100.
--anti-alias
Enable font and vector anti-aliasing. This option is not recommended.
Extraction--no-metadata
Don't extract the metadata.
By default:
• The following entries of the document information dictionary are extracted: Title, Author,
Subject, Creator, Producer, CreationDate, ModDate. Timestamps are formatted according to RFC3999[1], with date and time components separated by a single space.
• The XMP metadata is extracted (or created) and updated accordingly.
Note
If multiple input documents are specified, only metadata of the first one is taken into account.
--verbatim-metadata
Keep the original metadata intact.
--no-outline
Don't extract the document outline.
--hyperlinks=border-avis
Make hyperlink borders always visible.
By default, a hyperlink border is visible only when the mouse is over the hyperlink.
--hyperlinks=#RRGGBB
Force the specified border color for hyperlinks.
--no-hyperlinks, --hyperlinks=none
Don't extract hyperlinks.
--no-text
Don't extract the text.
--words
Extract the text. Record the location of every word. This is the default.
--lines
Extract the text. Record the location of every line, rather that every word.
--crop-text
Extract no text outside the page boundary.
--no-nfkc
Do not apply NFKC[2] normalization on the text, except for characters from the AlphabeticPresentationFormsblock[3] (U+FB00–U+FB4F), which are normalized unconditionally.
The default is to apply NFKC normalization on all characters.
--filter-text=command-line
Filter the text through the command-line. The provided filter must preserve whitespace, control
characters and decimal digits.
This option implies --no-nfkc.
-p, --pages=page-range
Specifies pages to convert. page-range is a comma-separated list of sub-ranges. Each sub-range is
either a single page (e.g. 17) or a contiguous range of pages (e.g. 37-42). Duplicate page numbers
are not allowed. Pages are numbered from 1.
The default is to convert all pages.
Performance-j, --jobs=n
Use n threads to perform conversion. The default is to use one thread.
-j0, --jobs=0
Determine automatically how many threads to use to perform conversion.
Verbosity,help-v, --verbose
Display more informational messages while converting the file.
-q, --quiet
Don't display informational messages while converting the file.
--version
Output version information and exit.
-h, --help
Display help and exit.
