Compress PNG
Cut PNG file size by resizing, or convert to WebP for the biggest savings.
Free · No watermark · Private — your image never leaves your browser
No upload wait and no queue — the image is processed on your device the moment you drop it in.
The whole thing runs in your browser on your device. Your image is never sent to a server.
Process as many images as you like. No sign-up, no watermark, no file-size paywall.
How it works
PNG is lossless, so re-saving it as PNG barely helps. The real win is WebP, which keeps transparency and looks identical at a fraction of the size, so we default your PNG to WebP for real compression (you can keep PNG if you prefer). Drop your PNG in, pick a level, and see exactly how much you save. Everything runs in your browser.
Frequently asked questions
Why is my compressed PNG barely smaller?⌄
PNG is lossless, so re-saving alone changes little. Reduce the width, or switch the output to WebP — WebP keeps transparency and is far smaller.
Does WebP keep PNG transparency?⌄
Yes. WebP supports an alpha channel, so transparent PNGs convert cleanly and end up much smaller.
Is anything uploaded?⌄
No — it all happens in your browser.
