Compress PNG
Colour-quantized PNGs that keep transparency.
Runs on your device. Files are never uploaded.
PNG compression works by reducing the number of colours (like TinyPNG and pngquant do) and then packing the result tightly. Transparency is preserved, and screenshots, logos and graphics shrink the most.

Questions
Is this lossless?
Choose "Lossless" for a re-packed PNG with identical pixels. The other levels reduce colours, which is what gives the big savings.
Are my files uploaded to a server?
No. The tool runs in your browser using your own device. Your file is never sent to us or anyone else — you can even disconnect from the internet after the page loads.
Is it really free?
Yes. There is no account, no watermark and no daily limit.
Is there a file size limit?
There is no fixed limit. Very large files depend on your device memory — a modern phone or laptop handles files of several hundred MB.
