Convert JPEG images to WebP locally in your browser. Same engine, same privacy — for files saved with the .jpeg extension.
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
“.jpg” and “.jpeg” are two extensions for exactly the same format — the shorter name dates back to older systems that limited file extensions to three letters. Whichever your files use, this page converts them to WebP the same way, entirely in your browser.
WebP uses newer, smarter compression than JPEG, so the same photo takes far fewer bytes at the same visible quality — typically 25–35% smaller, and much more for unoptimised exports. For websites, that means faster pages and better Core Web Vitals; for everyday sharing, it means smaller attachments and quicker uploads.
WebP also supports transparency and animation in a single format, and it displays in every modern browser, so converting is a safe upgrade.
Use WebP for publishing and sharing, and keep your original JPEG files as masters for editing or printing. dotwebp reads the file you drop in and creates a brand-new WebP — your source images are never altered or uploaded.
