JPEGOPTIM(1) General Commands Manual JPEGOPTIM(1)

NAME
jpegoptim - utility to optimize/compress JPEG/JFIF files.

SYNOPSIS
jpegoptim [ options ] [ filenames ]

DESCRIPTION
jpegoptim is used to optimize/compress jpeg files. Program supports lossless optimization, which is based on optimizing the Huffman tables. And so called "lossy" optimization where in addition to optimizing Huffman tables user can specify upperlimit for image quality.

NOTE! By default jpegoptim modifies the input files (if they are opti- mized), to preserve original files use option -d to specify alternate directory for saving the optimized files to.

Only normal files are optimized (symbolic links and special files are skipped). Also, any other hard links to the file being optimized (as created using link(2)) are unaffected.

OPTIONS
Options may be either the traditional POSIX one letter options, or the GNU style long options. POSIX style options start with a single ``-'', while GNU long options start with ``--''.

Options offered by jpegoptim are the following:

-d<path>, --dest=<path>
Sets alternative destination directory where to save optimized files (default is to overwrite the originals). Please note that unchanged files won't be added to the destination directory. This means if the source file can't be compressed, no file will be created in the destination path.

-f, --force
Force optimization, even if the result would be larger than the
original file.

-h, --help
Displays short usage information and exits.

-m<quality>, --max=<quality>
Sets the maximum image quality factor (disables lossless opti- mization mode, which is by default enabled). This option will re- duce quality of those source files that were saved using higher quality setting. While files that already have lower quality setting will be compressed using the lossless optimization method.

Valid values for quality parameter are: 0 - 100

-n, --noaction
Don't really optimize files, just print results.

-S<size>, --size=<size>
Try to optimize file to given size (disables lossless optimiza- tion mode). Target size is specified either in kilobytes (1 n) or as percentage (1% 99%) of the original file size.

-T<threshold>, --threshold=<threshold>
Keep the file unchanged if the compression gain is lower than the
threshold (%).

Valid values for threshold are: 0 - 100

-w<max>, --workers=<max>
Set the maximum number of parallel processes to launch. (Default is 1)

-b, --csv
Print progress info in CSV format.

-o, --overwrite
Overwrite target file even if it exists (when using -d option).

-p, --preserve
Preserve file modification times.

-P, --preserve-perms
Preserve file permissions (owner/group) by overwriting the origi- nal file. This is slightly less safe than the default mode of op- eration (where new file is first saved as temporary file and then renamed over the original file). In this mode a backup of the original file is made with . jpegoptim. bak extension, and this file is removed after the original file has been successfully re- placed. NOTE! if running jpegoptim as root there is generally no need to use this option, as jpegoptim is able to preserve file permissions when run by root in default mode.

-q, --quiet
Quiet mode.

-r, --retry
Recursively re-try compression until output file size does not
get smaller anymore. This can result a few bytes smaller output
file, but with the expense of lot more computing time used.

NOTE! This option is on only effective when used in compbination
with -m (--max) or -S (--size) option.

-t, --totals
Print totals after processing all files.

-v, --verbose
Enables verbose mode (positively chatty).

--auto-mode
Select progressive vs non-progressive mode based on which one produces smaller output file. By default mode (progressive vs non-progressive) is preserved.

--all-normal
Force all output files to be non-progressive. Can be used to con- vert all input files to non-progressive JPEGs when used with --force option.

--all-progressive
Force all output files to be progressive. Can be used to convert all normal (non-progressive) JPEGs input files to progressive when used with --force option. Progressive JPEG（渐进式 JPEG）：图像在编码时分成多个“扫描（pass）”层。加载时先显示一个整体模糊轮廓，然后随着更多数据到来，图像逐渐变清晰。

--all-arith
Force all output files to use Arithmetic Coding. This option is experimental and only available if jpegoptim was compiled with Arithmetic Coding support enabled.

--all-huffman
Force all output files to use (traditional) Huffman coding. This option is experimental and only available if jpegoptim was com- piled with Arithmetic Coding support enabled.

--nofix
Skip processing of any input files that have any errors/warnings during decompression. By default jpegoptim will attempt to opti- mize any file that it is able to decompress, even if decompres- sion generates warnings. This will 'fix' some (corrupt) JPEG images automatically. If this behaviour is not desired, this op- tion can be used to make jpegoptim to skip any input files that contain any errors.

--save-extra
Save extraneous data after end of the JPEG image in the input file (default is to discard any extraneous data after the end of image that may be present). This may be useful if JPEG image contains non-standard extensions that are not part of the JPEG image format. NOTE! This option does not work if input JPEG im- age is read from standard input (stdin).

--stdout
Send output image to standard output. Note, if optimization didn't create smaller file than the input file, then no output original image is passed through unmodified (except any extra data after JPEG image will be discarded).

--stdin
Read input image from standard input and send output to standard output (--stdout is assumed when this option is used). When this option is used then only one image is read from standard input. Any (other) input files specified on command-line are ignored. Note, if input file '-' is seen on command line then standard in- put is also assumed.

--files-stdin
Read names of files to process from standard input. One filename
per line.

--files-from=<filename>
Read names of files to process from a file. One filename per
line.

METADATA OPTIONS
By default jpegoptim will keep common metadata (JPEG markers) and dis- card any other (unknown ones).

Following markers are kept by default:
- EXIF
- IPTC
- ICC
- XMP
- COM (JPEG Comment markers)

JFIF marker will be regenerated (by libjpeg) during the process (this cannot be changed). However, Adobe marker is also generated (or omit- ted) by libjpeg based on the image colorspace, etc. This behavior de- pends on libjpeg library version being used. To make sure Adobe marker is preserved option --keep-adobe can be used.

To remove additional markers one or more the --strip-* options can be
used.

For example: --strip-icc --strip-xmp --strip-com

Alternatively it is possible to specify --strip-all and then one or
more of the --keep-* options to explicitly list which markers to keep

For example: --strip-all --keep-exif --keep-iptc

Options for controlling metadata (markers) in output files:

-s, --strip-all
Strip all markers from output file. (NOTE! by default only Com-
ment & Exif/IPTC/PhotoShop/ICC/XMP markers are kept, everything
else is discarded). Output JPEG still likely will contains one
or two markers (JFIF and Adobe APP14) depending on colorspace
used in the image, as these markers are generated by the libjpeg
encoder automatically.

--strip-none, --keep-all
Preserve "all" markers in the image. This will leave all markers
untouched in the image, except JFIF (APP0) and Adobe (APP14)
markers as those get regenerated by the libjpeg library.

NOTE! If this option is specified then any other --strip-* or
--keep-* options are ignored.

--strip-com
Strip Comment (COM) markers from output file.

--strip-exif
Strip EXIF markers from output file.

--strip-iptc
Strip IPTC / Adobe Photoshop (APP13) markers from output file.

--strip-icc
Strip ICC profiles from output file.

--strip-xmp
Strip XMP profiles from output file.

--strip-jfif
Strip JFIF markers from output file.

--strip-jfxx
Strip JFXX (JFIF Extensions) markers from output file.

--strip-adobe
Strip Adobe markers from output file.

--keep-com
Do not strip any Comment (COM) markers from output file.

--keep-exif
Do not strip any EXIF markers from output file.

--keep-iptc
Do not strip any IPTC / Adobe Photoshop (APP13) markers from out-
put file.

--keep-icc
Do not strip any ICC profiles from output file.

--keep-xmp
Do not strip any XMP profiles from output file.

--keep-jfif
Do not strip any JFIF markers from output file.

--keep-jfxx
Do not strip any JFXX (JFIF Extensions) markers from output file.

--keep-adobe
Do not strip Adobe markers from output file.

BUGS
When using --size option, resulting file is not always exactly the re- quested size. Workaround is to re-run jpegoptim on the same file again which often will result file closer to target size.
