The pngquant utility converts 32-bit RGBA PNGs to 8-bit RGBA-palette PNGs (or
|
||||
fewer than 8 bits, if you want), via quantization and ordered or diffusion
|
||||
(Floyd-Steinberg) dithering. You can also use it on RGB or even palette images
|
||||
(for example, to further color-reduce them to 16 colors). It does:
|
||||
- nice reduction of all PNG image types to 256-color (or smaller) palette
|
||||
- automatic optimization of tRNS chunks
|
||||
- batch conversion of multiple files (e.g., "pngquant 256 *.png")
|
||||
- Unix-style command-line filtering (e.g., "... | pngquant 16 | ...")
|
||||
It does still lack a few features:
|
||||
- no ancillary chunk preservation (except gAMA)
|
||||
- no preservation of significant-bits info after rescaling (sBIT chunk)
|
||||
- no mapfile support
|
||||
- no "native" handling of 16-bit-per-sample files or gray+alpha files
|
||||
(all samples are truncated to 8 bits and all images are promoted
|
||||
to RGBA before quantization)
|
||||
By the way, be sure to check "before" and "after" file sizes, preferably with
|
||||
pngcrush (http://pmt.sourceforge.net/pngcrush/); dithered palette images may
|
||||
be four times smaller to begin with, but they do not compress nearly as well
|
||||
as grayscale and truecolor images. Some images, such as Henri Sivonen's alpha
|
||||
button (http://www.pp.htv.fi/hsivone1/css-test/bitmapstyle.html), can be made
|
||||
smaller as full 32-bit RGBA images (4076 bytes in this case) than as either
|
||||
FS-dithered palette (4550 bytes) or ordered-dither palette (4482 bytes) images.
|
||||
pngquant is a command-line utility to quantize and dither 32-bit RGBA
|
||||
PNGs down to 8-bit (or smaller) RGBA-palette PNGs, usually with a
|
||||
significant reduction in file size (40-70% smaller than 24-bit PNGs).
|
||||
|
||||
WWW: http://www.libpng.org/pub/png/apps/pngquant.html
|
||||
This unique type of PNG supports full alpha transparency and is
|
||||
compatible with all modern web browsers, and has better fallback in IE6
|
||||
than 24-bit PNGs.
|
||||
|
||||
Features:
|
||||
- High-quality palette generation using modernized Median Cut
|
||||
algorithm.
|
||||
- Unique dithering algorithm that adds less noise to images than the
|
||||
standard Floyd-Steinberg.
|
||||
- Easy to integrate with shell scripts, GUIs and server-side software.
|
||||
- Fast mode for processing large numbers of images.
