Convert JPG to WEBP
Convert JPG to WEBP for free. Files never leave your device: the conversion runs in your browser, works offline, no upload, no limits.
Drop files here or click to choose
Your files stay on this device. Nothing is uploaded.
JPG (JPEG) is the most compatible photo format. Lossy: each save discards a little detail, so convert once and keep the original. WEBP is Google's web format: 25–35% smaller than JPG, supports transparency and animation. Some older apps and photo editors still reject it. This converter turns one into the other directly on your device, so your files are never uploaded anywhere.
How it works
- Drop your JPG files here or click to pick them (many at once is fine).
- Choose the quality; 80 gives files 25–35% smaller than the JPG with no visible change.
- Click Convert. Download each WEBP or all of them as a ZIP.
This tool runs entirely in your browser. Your files are never uploaded, so there is no size limit and it works offline once loaded.

Frequently asked questions
Is it really free and private?
Yes. There is no server: your browser does the conversion with open-source code. Your files never leave your computer or phone, which also means there is no file-size limit and it works offline once the page has loaded.
Will I lose quality converting JPG to WEBP?
Any conversion into a lossy format discards a little detail. At the default quality the difference is invisible for photos; keep the original if you may need to edit it again.
Does it work on iPhone and Android?
Yes, in Safari and Chrome. Very large batches may be limited by your phone's memory; convert in groups if a batch fails.
