Crunch - Insane(ly slow but wicked good) PNG image optimization

  •    Python

Crunch is a tool for lossy PNG image file optimization. It combines selective bit depth, color type, and color palette reduction with zopfli DEFLATE compression algorithm encoding using the pngquant and zopflipng PNG optimization tools. This approach leads to a significant file size gain relative to lossless approaches at the expense of a relatively modest decrease in image quality (see example images below). Historical benchmarks with the files included in Cédric Louvrier's PNG Test Corpus versus other commonly used PNG optimization software are available in BENCHMARKS.md.

imagemin-zopfli - zopfli plugin for imagemin

  •    Javascript

Convert 16-bit per channel image to 8-bit per channel.Allow altering hidden colors of fully transparent pixels.

optimise-images - Batch image resizer, optimiser and profiler using ImageMagick convert, OptiPNG, JpegOptim and optional ZopfliPNG, Guetzli and MozJPEG

  •    Shell

Batch jpg, jpeg and png image resizer, optimiser and image profiler using ImageMagick convert, OptiPNG, JpegOptim and optional Mozilla MozJPEG, ZopfliPNG and Google Guetzli (work in progress for Guetzli). Profile original images via script's profile flag and pass the directory path to the directory containing the images you want to optimise /home/nginx/domains/domain.com/public/images. This is your baseline to compare resizing and optimisations applied to images using above default variable parameters.
