Compress an image now

PNG is lossless, which keeps text and logos sharp but often makes files large. This compressor reduces a PNG's size by optimising its colours and encoding — so a screenshot, logo or graphic downloads and loads far faster while still looking clean.

Transparency is preserved, there's no watermark, and because everything runs in your browser your image is never uploaded. Drop in one PNG or a whole batch.

Frequently asked questions

Will compressing a PNG lose quality?

PNG compression here focuses on reducing colour data and re-encoding, which for most graphics, logos and screenshots is visually lossless. For photographs, converting to WEBP or JPG usually saves far more.

Does it keep transparency?

Yes. The alpha channel is preserved, so a transparent PNG stays transparent after compression.

Is there a file limit or watermark?

No limits and no watermark. It's free and unlimited, and your images never leave your browser.
