Worth knowing before you convert
- Both JPG and WebP are lossy, so this re-encodes an image that already lost some detail. The loss is small at our automatic quality, but it does not come back. Keep your original if you may need to convert again later.

Your own file will land somewhere else — a photo, a screenshot and a flat logo compress very differently. What carries over is the direction and the rough scale.
Questions about JPG to WebP
How do I convert JPG to WebP?
Drop your JPG files onto the box above, pick a quality level if you want to override the automatic one, and press convert. The WebP files download straight back to you — a single file on its own, or a ZIP when you convert several at once.
Is converting JPG to WebP free?
Yes. There is no account, no watermark, and no per-file charge. Conversion runs on our servers, so it does not depend on how fast your own machine is.
Are my files stored anywhere?
No. Files are held in memory only while the conversion runs and are discarded the moment the result is sent back. Nothing is written to disk and nothing is written to a database.
Will the quality drop?
WebP stores every pixel it is given. It cannot restore detail that JPG already discarded, but it will not remove any more.
Why choose WebP over JPG?
Google's replacement for both JPG and PNG. Typically 25-35% smaller than JPG at matching quality, with transparency support. The default for the web today — smaller pages without a visible quality cost. Browser support: Every current browser.
