PNG Compressor
Shrinks PNGs with color quantization for real savings, with a lossless option for when you can't give up a single pixel.
What this does
Shrinks PNG images using color quantization — the same engine pngquant uses — to cut real file size while keeping the output losslessly repacked. A lossless option is available when you need every original pixel preserved.
How it works
- 1Drop your PNGs or pick them.
- 2Pick a color count, or keep it lossless.
- 3Download each one, or grab them all as a zip.
Built with open source
