Can I compress a WebP that's already small?

You can, but the gains will be modest if it was already saved at a low quality. Resizing the image is the most effective additional lever.

Does compressing WebP keep transparency?

Yes. Re-encoding to WebP preserves the alpha channel, so transparent areas stay transparent.

What quality should I pick?

For photos, 75–85% balances size and quality well. For graphics with sharp edges, stay at 90%+ to keep lines clean.

Is anything uploaded?

No. Compression runs in your browser; your files never leave your device.

Compress WebP — Reduce WebP File Size in Your Browser

Squeezing a WebP smaller

WebP is already one of the most efficient image formats, so a WebP file is often near its practical floor. Still, there are two situations where compressing further pays off: the WebP was exported at a high quality (90–100%) and you want it leaner, or the image is larger in pixel dimensions than it needs to be. This page re-encodes your WebP at the quality you choose, and lets you resize at the same time.

Quality and dimensions

The same two levers apply as with any lossy format:

Quality slider — for photographs, 75–85% trims size noticeably with no visible loss. For logos, icons, and screenshots, keep it at 90%+ so edges and text stay crisp.
Max width — if the image is shown smaller than its native resolution, scaling it down is the most powerful reduction available, and it compounds with the quality setting.

Transparency is kept

Re-encoding WebP to WebP preserves the alpha channel, so any transparent background stays intact.
