WebP is JPG’s modern replacement: 25–35% smaller at the same visual quality, with alpha support JPG never had. Converting your JPG library to WebP is the cheapest site-speed win there is — this tool does it in your browser, one file at a time, free.
Everything stays on your device: the conversion runs in your browser tab using the browser’s own image encoder. Drop a JPG (or JPEG), get a WebP at full resolution in about a second.
Compatibility is a non-issue in 2026: Chrome, Edge, Firefox, Safari, WordPress, Shopify and every major social platform accept WebP. The stragglers that don’t are the same ones that can’t render this decade’s web.
Frequently asked questions
- Is WebP really better than JPG?
- At the same visual quality, WebP files are typically 25–35% smaller. That means faster pages, smaller uploads and more photos in the same storage.
- Will I lose quality converting JPG to WebP?
- We encode at 92% quality — the difference is imperceptible for photos. The WebP will look identical to your JPG at a fraction of the size.
- Does WebP support transparency like PNG?
- Yes — WebP has a full alpha channel, which is why it replaces both JPG (size) and PNG (transparency) in one format.
