FLIF - Free Lossless Image Format
UPDATE FLIF development has stopped since FLIF is superseded by FUIF and then again by JPEG XL, which is based on a combination of Pik and FUIF. For more information, see Jon's JXL info page or visit the JPEG XL Discord server. FLIF - Free Lossless Image Format FLIF is a novel lossless image format which outperforms PNG, lossless WebP, lossless BPG, lossless JPEG2000, and lossless JPEG XR in terms
pngquant — lossy PNG compressor
pngquant is a command-line utility and a library for lossy compression of PNG images. The conversion reduces file sizes significantly (often as much as 70%) and preserves full alpha transparency. Generated images are compatible with all web browsers and operating systems. Features High-quality palette generation using a combination of vector quantization algorithms.

DD_belatedPNG: better PNG background-image support in IE6
Long story short, this uses Microsoft's implementation of VML instead of Microsoft's AlphaImageLoader filter. I stumbled upon the notion that PNG images show up correctly in a VML fill element while working on DD_roundies. Thereafter, some Googling revealed that a few people had already known about this. The intended implementation is pretty easy: Download a copy of the DD_belatedPNG Javascript fi
optipng home page
optiPNG is a PNG optimizer that recompresses image files to a smaller size, without losing any information. This program also converts external formats (BMP, GIF, PNM and TIFF) to optimized PNG, and performs PNG integrity checks and corrections. If you wish to learn how PNG optimization works, or to know about other similar tools, see the PNG Tech article A guide to PNG optimization. DOWNLOAD opti

phpThumb() - The PHP thumbnail generator
phpThumb() uses the GD library to create thumbnails from images (JPEG, PNG, GIF, BMP, etc) on the fly. The output size is configurable (can be larger or smaller than the source), and the source may be the entire image or only a portion of the original image. True color and resampling is used if GD v2.0+ is available, otherwise paletted-color and nearest-neighbour resizing is used. ImageMagick is u
