Files never leave your device. Everything runs in your browser, nothing touches a server — tools you've used even work offline.
Convert JPG photos to WebP right in your browser — no uploads, no accounts, files never leave your device. WebP typically lands 25–35% smaller than JPG at the same visual quality, which is why it is the default choice for fast websites. Batch-convert and download everything as a ZIP.
How it works
- Drop files anywhere on the page, click to browse, or paste with ⌘V.
- Pick a quality or preset — or set an exact target size and let the tool find it.
- Compress, compare before/after, and download — individually or as a ZIP.
Why websites serve WebP
The 25–35% saving is not marketing — WebP simply encodes photos tighter than a format from the early nineties can. On a website that compounds into faster pages, better search rankings and lower bandwidth on every single visit, which is why performance-minded sites converted their image libraries years ago.
When JPG should stay JPG
Off the web, JPG is still king: email attachments, print shops, older desktop software and plenty of upload forms refuse WebP. The practical setup is both — keep the JPG as the compatible master and serve WebP copies on your site. If the master itself is heavy, Compress JPG shrinks it without changing format.
Frequently asked questions
Why convert JPG to WebP?
Smaller files at the same quality — usually 25–35% savings. Every modern browser supports WebP, so for websites it is nearly free page speed.
When should I stay with JPG?
When the image leaves the web: email attachments, older desktop software, print shops, and some upload forms still expect JPG. For maximum compatibility, JPG remains the safe bet.
Can I convert a whole folder and set an exact size?
Yes — drop the batch, optionally switch to target-size mode with a per-file limit, and download the results as one ZIP.
Are photos uploaded to a server?
No — the pixels never leave your machine. Decoding and re-encoding both happen in your browser; there is no upload to wait for and no server-side copy to worry about afterwards. Want proof? Run one file through, switch your connection off, and run another — it still works.
