WebP generally reaches the same visual quality as JPG in a noticeably smaller file, which is why this conversion is usually about page weight — a gallery, a product listing, a site that has to load quickly on mobile data.
Keep in mind that the source is already lossy. Converting re-compresses it, so pick a high quality setting rather than chasing the smallest possible file, and keep the JPG originals.

How it works
- Choose one or more JPG files.
- Set the quality; start high and lower it only if the size is still too big.
- Convert and download the WebP files.
Frequently asked questions
How much smaller are the files?
It varies with the picture, but a meaningful reduction at matching quality is typical. Busy, textured photographs benefit less than smooth ones.
Will visitors be able to see WebP?
Every current browser displays WebP. The gap is outside the browser, in desktop software and upload forms, which is why people convert back the other way.
Is converting twice a problem?
Each lossy save costs a little quality. Convert from the original JPG rather than from a file that has already been through another conversion.
