Accepts WEBP images · max 25.00 MB
How to use it
- 1Drop a WEBP file into the upload area.
- 2Set the quality slider. The browser's WebP encoder is lossy at every value here, so even 100 is a re-encode rather than a copy.
- 3Press Compress and read the measured before/after bytes.
- 4Download if the saving is worth it — if the panel says 'Larger', your source was already more aggressively compressed than the setting you chose.
Frequently asked questions
My WEBP is already small. Is there anything left to squeeze?
Often not much. WebP is already 25–35% denser than JPG at the same visual quality, so a second pass mostly costs detail. Reducing dimensions is usually the better lever.
Does compressing a lossless WEBP turn it lossy?
Yes. The output here is encoded with a quality value, so a lossless source becomes a lossy file. Keep the original if you need to edit it later.
What if my browser can't encode WebP?
Support is checked with a real test encode before anything runs, not by sniffing the user agent. If encoding genuinely isn't available you get a clear message instead of a mislabelled file.
Is transparency preserved when compressing?
Yes — lossy WebP supports an alpha channel, so transparent areas survive the re-encode.
