PNG is lossless, so the biggest wins come from reducing the colour palette and scaling the image down. This tool does both locally, and can also export the image as WebP — often 60–80% smaller than PNG with no visible difference.

Frequently asked questions
Why is my PNG still large?
Photographic PNGs don't compress well. Either resize it, reduce colours, or export as WebP/JPG for a dramatic size cut.
Is PNG Compressor free?
Yes — PNG Compressor is free with no account, no watermark, and no file-count limit.
Are my files uploaded?
No. The compression runs entirely in your browser with the Canvas API. Your files never leave your device.
Will quality drop?
You control it. A higher quality setting keeps the file closer to the original; a lower setting makes it smaller. Preview the output size before you download.
