Compress WebP Images Online

Shrink a WebP to a target percent of its original bytes, or switch to JPG if the destination cannot open WebP. The slider is file size, not a quality label.

The slider is a file-size target, not JPEG quality. 50% means we aim for about half the original bytes, without going over.

Tightening WebP files

WebP is already efficient, but exports from design tools can still overshoot a CMS limit. This page starts from WebP and searches for a smaller WebP (or lets you compare with JPG if you switch output in the general compressor). Because WebP can be lossy, another pass can soften detail—preview before you replace production assets.

If a partner cannot open WebP, compress and then convert to JPG with the converter tools rather than emailing a format they cannot preview.

A worked example and help

Need a portal limit? Start with the exact byte cap and check minimum dimensions too. Our generated 733,759-byte JPG reached 99,526 bytes at 1200 × 800 in the measured Chrome run; that result is source-specific and uses lossy quality 15.

FAQ

Can I keep WebP output?

Yes. This page starts with WebP. Switch to JPG only if you need a file older software can open.

Does 50% mean quality 50?

No. 50% means we aim for half the original file size, without going over. Encoding is searched automatically.

Are images uploaded?

No. The new file is created in this browser and downloaded from a local blob.
