The format-agnostic converter: drop in any browser-supported image and get optimized WebP back — all on your device.
How it works
Convert a whole batch to WebP without sending anything to a server.
01
Pick a file or drag it straight in — JPG, PNG, GIF and more are all welcome.
02
Slide between smaller and sharper. 80 is a great default for most photos.
03
It saves straight to your device the moment it’s ready — no upload, no waiting.
Why WebP
Learn
This is the format-agnostic converter: drop in JPG, JPEG, PNG, GIF or BMP and get an optimised WebP back. Output is always WebP, so you get a single, consistent, web-friendly format no matter what you started with.
Everything is processed on your own device using your browser’s built-in image engine, so there are no uploads, no accounts and no waiting in a queue.
Photographs (JPG/JPEG) shrink significantly while keeping their detail. PNGs keep their transparency. BMPs — which are usually huge and uncompressed — often see the biggest savings of all. Animated GIFs are converted to a still WebP using the first frame, since the goal here is small, sharp images rather than animation.
Maintaining a mix of JPGs, PNGs and BMPs across a site is harder to optimise and cache. Converting everything to WebP gives you one modern format with excellent compression and universal browser support — simpler to manage and faster for visitors.
| Source | WebP | |
|---|---|---|
| JPG / JPEG | Photos | 25–35% smaller, same look |
| PNG | Graphics & transparency | Much smaller, alpha kept |
| BMP | Uncompressed | Massive size reduction |
| GIF | Animation | First frame as a still WebP |
| Output | Mixed formats | One consistent WebP |
