FAQ
How much smaller will the WebP be?
Usually 25–30% at similar visible quality, and more for images with large smooth areas. The result panel shows the actual change for your file.
Is quality lost?
A little — this is a second lossy pass. At the default quality of 82 it is not visible on photographs. Convert from the highest-quality JPG you have rather than from a web-sized copy.
Do all browsers support WebP?
Yes, and they have for years. The gap is in older desktop applications and print workflows, not on the web.
Should I convert my whole photo library?
For images you serve on a site, yes. For originals, no — keep the JPGs as masters. Converting an archive to a lossy format and deleting the source cannot be reversed.
Can I resize at the same time?
Yes. Set a maximum width in the advanced options and the image is scaled proportionally before encoding, which usually saves far more than the format change alone.
Is it really free?
Yes — every conversion on this site, with no account, no watermark and no daily cap. The work happens on your own device, so there is no server bill for us to pass on to you.
Do I need to install anything?
No. It runs in any modern browser, on Windows, macOS, Linux, Android and iOS. There is nothing to download and nothing to sign up for, and once the page has loaded it keeps working with the network switched off.
