Convert PNG to WebP

Transparency like PNG, file sizes closer to JPEG. The modern answer for the web.

Upload your PNG.
It is re-encoded as WebP with transparency kept.
Download the smaller file.

WebP is the format that resolves the usual dilemma. It supports full alpha transparency the way PNG does, but compresses far more efficiently — commonly 25–50% below an already-compressed PNG, and dramatically below a photographic one.

Every current browser supports it. The one place to be careful is anywhere the file will be opened by older desktop software, which may not read WebP at all — keep a PNG for those.

Frequently asked questions

Is WebP smaller than a compressed PNG?

Usually yes, often substantially — and the gap widens the more photographic the image is.

Does WebP support transparency?

Yes, a full alpha channel, exactly like PNG. That is what makes it a real replacement rather than a compromise.

Will WebP work everywhere?

In browsers, yes — support is universal in current versions. Some older desktop applications still cannot open it, so keep a PNG copy if the file has to travel outside the web.
