MUTOOL(1)

NAME
mutool - all purpose tool for dealing with PDF files

SYNOPSIS
mutool <sub-command> [options]

VERSION
mutool -v

Shows the MuPDF version used to build mutool.

DESCRIPTION
mutool is a tool based on MuPDF for dealing with document files in various manners. There are several sub commands available, as described below.

DRAW
mutool draw [options] file [pages]

The draw command will render a document to image files, convert to another vector format, or extract the text content.

The supported input document formats are: pdf, xps, cbz, and epub.

The supported output image formats are: pbm, pgm, ppm, pam, png, pwg, pcl and ps. The supported output vector formats are: svg, pdf, and debug trace (as xml). The supported output text formats are: plain text, html, and structured text (as xml).

-p password
    Use the specified password if the file is encrypted.

-o output
    The output format is inferred from the output filename. Embed %d in the name to indicate the page number (for example: "page%d.png"). Printf modifiers are supported, for example "%03d". If no output is specified, the output will go to stdout.

-F format
    Enforce a specific output format. Only necessary when outputting to stdout since normally the output filename is used to infer the output format.

-q  Be quiet, do not print progress messages.

-R angle
    Rotate clockwise by given number of degrees.

-r resolution
    Render the page at the specified resolution. The default resolution is 72 dpi.

-w width
    Render the page at the specified width (or, if the -r flag is used, render with a maximum width).

-h height
    Render the page at the specified height (or, if the -r flag is used, render with a maximum height).

-f  Fit exactly; ignore the aspect ratio when matching specified width/heights.

-b box
    Use name page box (`MediaBox`, `CropBox`, `BleedBox`, `TrimBox`, or `ArtBox`), see :ref:`defined boxes<mutool_trim_defined_boxes>`.

-B bandheight
    Render in banded mode with each band no taller than the given height. This uses less memory during rendering. Only compatible with pam, pgm, ppm, pnm and png output formats. Banded rendering and md5 checksumming may not be used at the same time.

-T threads
    Number of threads to use for rendering (banded mode only).

-W width
    Page width in points for EPUB layout.

-H height
    Page height in points for EPUB layout.

    Font size in points for EPUB layout.

-U filename
    User CSS stylesheet for EPUB layout.

-a  Disable usage of accelerator file.

-c colorspace
    Render in the specified colorspace. Supported colorspaces are: mono, gray, grayalpha, rgb, rgbalpha, cmyk, cmykalpha. Some abbreviations are allowed: m, g, ga, rgba, cmyka. The default is chosen based on the output format.

-e filename
    Proof ICC profile filename to use for rendering.

-G gamma
    Apply gamma correction. Some typical values are 0.7 or 1.4 to thin or darken text rendering.

-I  Invert colors.

-s [mft5]
    Show various bits of information: m for glyph cache and total memory usage, f for page features such as whether the page is grayscale or color, t for per page rendering times as well statistics, and 5 for md5 checksums of rendered images that can be used to check if rendering has changed.

-A bits
    Specify how many bits of anti-aliasing to use. The default is 8.

-A bits/bits
    Specify how many bits of anti-aliasing to use. The default is 8. Bits for graphics is before the slash, bits for text after the slash.

-l width
    Minimum stroked line width (in pixels).

-K  Do not draw text.

-KK Only draw text.

-D  Disable use of display lists. May cause slowdowns, but should reduce the amount of memory used.

-i  Ignore errors.

-m limit
    Limit memory usage in bytes.

-L  Low memory mode (avoid caching objects by clearing cache after each page).

-P  Run interpretation and rendering at the same time.

-N  Disable ICC workflow.

-O overprint
    Control spot/overprint rendering: 0 for no spot rendering, 1 for Overprint simulation (default), or 2ffull spot rendering.

CLEAN
mutool clean [options] input.pdf [output.pdf] [pages]

The clean command pretty prints and rewrites the syntax of a PDF file. It can be used to repair broken files, expand compressed streams, filter out a range of pages, etc.

If no output file is specified, it will write the cleaned PDF to "out.pdf" in the current directory.

-p password
    Use the specified password if the file is encrypted.

-P permissions
    Permissions used when encrypting output file. These are the permissions that apply when the output file is viewed.

-a  ASCII Hex encode binary streams. Use in conjunction with -d and -i or -f to ensure that although the images and/or fonts are compressed, the resulting file can still be viewed and edited with a text editor.

-d  Decompress streams. This will make the output file larger, but provides easy access for reading and editing the contents with a text editor.

-z  Deflate uncompressed streams. If combined with -d, any decompressed streams will be recompressed. If combined with -a, the streams will also be hex encoded after compression.

-e effort
    Configure how much effort is spent compressing the output file. 0 is default amount, otherwise a percentage of the maximum effort, 1 for minimum and 100 for maximum effort.

-c  Pretty-print graphics commands in content streams.

-s  Sanitize graphics commands in content streams, this means, for example, removing invalid or redundant commands.

-t  Use compact PDF object syntax. This saves space.

-tt Use indented PDF object syntax. This is more human-readable.

-L  Print comments containing labels showing how each object can be reached from the Root.

-A  Create appearance streams for annotations that are missing appearance streams.

-AA Recreate appearance streams for all annotations.

-m  Preserve metadata.

-S  Subset fonts if possible. (EXPERIMENTAL!)

-Z  Use object streams cross reference streams for extra compressoin.

RUN
mutool run script.js [arguments]

Executes a Javascript program which has access to most of the features of the MuPDF library. The command supports ECMAScript 5 syntax in strict mode. All of the MuPDF constructors and function live in the global object, and the command line arguments are accessible from the global argv object.

If invoke without any arguments, it will drop you into an interactive REPL (read-eval-print-loop). On the interactive prompt, if you prefix a line with an equal character it will automatically print the results of the line.

See the MuPDF documentation for details about the Javascript interfaces.
