My favourite tool for one-off losless image optimization is FileOptimizer, each asset is processed with several size optimization libraries. https://nikkhokkho.sourceforge.io/static.php?page=FileOptimizer. - Source: Hacker News / over 1 year ago

Good stuff. I use optipng and other things via https://nikkhokkho.sourceforge.io/static.php?page=FileOptimizer before I upload any image to anywhere where others might download them. - Source: Hacker News / over 1 year ago

Ok what about https://imageoptim.com/mac or https://nikkhokkho.sourceforge.io/static.php?page=FileOptimizer Like, fileoptimizer uses tons more PNG optimisers. - Source: Hacker News / almost 2 years ago

I have had good experiences with https://github.com/shssoichiro/oxipng . Although, I suspect this wouldn't give you nearly enough space savings as jpg. Source: 11 months ago

If you do want the file as a PNG (for transparency and a common format that's well supported), but don't want it so huge, consider something like oxipng. https://github.com/shssoichiro/oxipng. Source: about 1 year ago

I wonder how `pngcrush` compares to `oxipng` (https://github.com/shssoichiro/oxipng). Personally, I use `oxipng` if I want lossless compression. However, most of the time, I use `pngquant` instead, since it gives significant size reduction even at `99%` (I can't even distinguish between the original and reduced image).

    pngquant --quality=99 --ext=.png --force file.png

Depending on your workflow it might make sense to export PNGs directly from Affinity and then reduce their size with a utility like Oxipng, which uses all your cores to find the best algorithm for each particular image. Source: almost 2 years ago
