Compress WebP images with a quality slider
This WebP compressor re-encodes a WebP image at a lower quality setting and shows the size saving before you download. Choose a WebP file, set the quality slider, and compare the compressed size with the original. It is the same simple loop as the other compressors here, kept specific to the WebP format and its files. No account, queue or upload is involved at any stage.
When a WebP needs a second pass
WebP files are usually created small, but exports made for quality rather than size, or images converted from large originals, can still carry more weight than a page needs. A second pass at a slightly lower quality suits web images that will be displayed at modest sizes, where the difference is hard to see but the saving helps loading.
Good to know
WebP output requires your browser to support WebP encoding; if it cannot encode WebP, the tool shows a clear message rather than silently handing you a different format. Files up to 10 MB are accepted, and your original file is never modified on your device.
Frequently asked questions
What if my browser cannot encode WebP?
The tool will tell you rather than guess. Displaying and encoding WebP are separate browser abilities, and without encoding there is no honest way to produce a compressed WebP in the browser. A current Chrome, Edge or Firefox usually works.
Is WebP compression lossy here?
Yes. Lowering quality trades detail for a smaller file, the same trade as JPG. Before and after sizes show before download, and your original stays untouched, so you can rerun at higher quality.
Are my images uploaded to a server?
No. Files are processed in your browser and never sent to the site's server. The file stays on your device throughout, and the download is generated locally.
