{ } How it works
JPG to WebP works on the file you upload. Adjust the options, then select Process ▸ and it runs entirely in your browser — nothing is uploaded to a server — then shows the result in the Output panel.
Inputs
- JPG image — upload a file (.jpg,.jpeg,image/jpeg); it is read locally in your browser
- Quality (1–100) — a value (default: "90")
Output
A downloadable WEBP file — use the Download button in the Output panel.
{ } Common uses
- Cut the weight of photographs on a web page.
- Get a smaller file at the same visual quality than JPEG can manage.
- Prepare images for a site that serves WebP.
{ } Limitations
- Both formats are lossy, so this is a second lossy encode on top of the first. At quality 90 the extra loss is hard to see, but it is real, and going lower compounds it.
- How much you save depends entirely on the picture. A busy photograph may barely shrink while a flat graphic shrinks a great deal.
- Metadata is dropped in the canvas round-trip.
{ } FAQ
Is my data uploaded to a server?
No. Everything runs locally in your browser — your files never leave your device.
Can I process more than one file at once?
Yes — add several files and they’re all processed and downloaded together as a ZIP.
Is this tool free?
Yes — it’s completely free and needs no sign-up.
Is WebP safe to use now?
In a browser, yes — every current one has decoded it for years. The remaining caution is outside the browser: some older desktop software and a few upload forms still refuse it, and that is when JPG stays the safer choice.
