git clone https://github.com/heydeer/pngdeer.git
Lossy PNG compressor that searches palette sizes and dithering per image, keeping the smallest file that still looks right.
Why you might care
Use it instead of a fixed-quality tool like TinyPNG when you want smaller PNGs without picking a quality value; the README claims 8-12% smaller files than TinyPNG at equal quality. Works as a CLI on macOS and Linux or in the browser via WebAssembly, with images processed locally and not uploaded.
