pngquant VS pngcrush

Image-shrinker is a simple, easy to use open source tool for shrinking images. Under the hood it uses pngquant, mozjpg, SVGO, and gifsicle. You can also install these tools individually if you need to compress some images. I often use pngquantafter exporting PNGs for web projects from Figma or similar tools.

Searching more I found https://pngquant.org/ which I could add to my bulk workflow to make most png's approach the jpeg size. Source: 11 months ago

But this did prompt me to do some searching, and I see https://pngquant.org/ which seems to achieve jpeg like size reduction while maintaining the file as a png. One difference they note is that this method will typically preserve sharp edges better than jpeg (which is probably a strong plus for my type of use case). Source: 11 months ago

Pngquant is also great for shaving filesizes down, but unlike oxipng, it's explicitly lossy. It'll reduce colors and even dither, but it will try to keep an image visually similar. Https://pngquant.org/. Source: about 1 year ago

Did you compare to PNG crush and optipng? Those are what I used to use because they're easily installable Linux/brew packages. Source: about 1 year ago

My god running pngcrush on the 2x and 3x files takes ages. I run the thing overnight because it takes hours. Source: over 1 year ago

I've always just used this (it's more old school but def solid): https://pmt.sourceforge.io/pngcrush/. - Source: Hacker News / almost 3 years ago
