Compress PNG
Drop your PNGs to shrink their file size on your device. Great for web pages and email — and because PNG is lossless, the pixels stay sharp.

Nothing is uploaded. Your images never leave this browser.
Tip: for photos, switching the format to WEBP or JPG usually shrinks the file far more than PNG can.
FAQ
Is compressing PNG free?
Yes — free, unlimited, no signup and no watermark. There is no server, so there is nothing to charge for.
Are my images uploaded?
No. It all runs inside your browser. Your images never leave your device.
Will quality drop?
You control it with the quality slider and can see the exact file-size saving for every image before you download.
