WebP · WebP (re-compression)

Compress WebP images online

Already using WebP but the files are still too big? Many exporters save WebP at 100% quality or full camera resolution. Re-compress them here with a sensible quality and maximum width and cut another 50–80% without uploading anything.

Why convert WebP to WebP?

Fix over-sized exports. Design tools often write WebP at quality 100, which is barely smaller than PNG.

Downscale in one step. A 4000 px WebP displayed at 1200 px wastes 90% of its bytes.

Preserve transparency. Alpha channels survive re-encoding.

Step 3

Cap the width

Set the maximum width to your largest display size, usually 1200–2000 px.

Step 4

Convert and compare the before/after size in the results list.

Why WebP files can still be too large

WebP is only as small as its encoder settings. Photoshop, Figma and many CMS plugins default to quality 90–100, and lossless WebP (the default for some PNG converters) is often larger than a good lossy JPEG. Re-encoding with a quality between 75 and 85 typically halves the size with no visible change.

Generation loss

Re-compressing a lossy image a second time adds a small amount of extra degradation. One re-compression at 80% is harmless; ten rounds are not. Whenever possible, re-export from the original source instead of compressing a compressed file.

WebP to WebP: questions

Reducing the width to the size the image is actually displayed at is effectively free. Lowering the quality from 100 to 85 is visually lossless for almost all images.

Yes. The alpha channel is preserved when re-encoding.
