picopt 1.0.2

Optimize image files and comic archives with external tools

Latest Version: 1.5.3

A multi-format, recursive, multiprocessor aware, command line image optimizer utility that uses external tools to do the optimizing.

Picopt depends on Python PIL to identify files and rarfile to open CBRs.

To optimize JPEG images. Picopt needs either jpegrescan or jpegtran on the path. jpegrescan is preferred.

To optimize lossless images like PNG, PNM, GIF, TIFF and BMP, picopt requires either optipng, advpng or pngout be on the path. optipng provides the most advantage, but best results are acheived by using both utilities. advpng support is disabled by default and must be explicitly enabled on the command line.

Animated GIFs are optimized with gifsicle if it is available.

Picopt uncompresses, optimizes and rezips comic book archive files. Be aware that CBR rar archives will be rezipped into CBZs instead of CBR.

Picopt allows you to drop picopt timestamps at the root of your recursive optimization trees so you don’t have to remember which files to optimize or when you last optimized.


Lossless external programs


brew install optipng pngout jpeg gifsicle

Debian / Ubuntu

apt-get install optipng pngout libjpeg-progs gifsicle

Redhat / Fedora

yum install optipng pngout libjpeg-progs gifsicle


git clone
ln -s jpegrescan/jpegrescan /usr/local/bin/jpegrescan


Debian / Ubuntu

apt-get install python-imaging


pip install picopt


Optimize files:

picopt *.jpg

Optimize files and recurse directories:

picotpt -r *

Optimize files and recurse directories AND optimize comic book archives:

picopt -rc *

Optimize files, but not lossless files:

picopt -OPG *

Optimize files, but not jpegs:

picopt -JT *

Optimize files, but not animated gifs:

picopt -G *

Just list files would try to optimize:

picopt -l *

Optimize everything in my iPhoto library, but only after the last time i did this, skipping symlinks to avoid massive amounts of duplicate work. Don’t convert lossless files to PNGs because that would confuse iPhoto. Also drop a timestamp file so I don’t have to remeber the last time I did this:

picopt -rSYt -D '2013 June 1 14:00' 'Pictures/iPhoto Library'

Packaged For


imageoptim is an OS X GUI optimizer. It integrates the various optimization programs so you don’t have to install them separately. It does not handle comic book archives. Its drag’n’drop UI is pretty nice. It also has AdvPNG support which I’ve disabled in picopt because I’ve never seen it provide any advantage. Command line usage is possible with an external program.
