Convert an image to WebP
WebP usually gets you the same picture for a quarter to a third fewer bytes. Usually. This page converts your files and reports the actual number for each one, so you can decide per image rather than on faith.

When WebP is worth it, and when it is not
WebP wins most clearly on photographs at moderate quality, where its smarter prediction and entropy coding pull ahead of JPEG's ageing design. It wins enormously on images that combine photographic areas with flat colour and hard edges, because it can switch approaches within a single image where JPEG cannot.
It wins least on small images, where fixed container overhead is a bigger share of the total, and on images that were already compressed hard as JPEG, where you are simply re-encoding damage. Converting an old, heavily compressed JPEG to WebP often produces a larger file that also looks slightly worse. The per-file report will show you when that has happened.
Lossless WebP is a genuinely good replacement for PNG, typically 20 to 30% smaller with identical pixels, and it keeps transparency. If you are shipping icons, logos or screenshots to a web page, that is the mode to use.
Browser support
Every current browser handles WebP, and has done since 2020. The only reason to keep a JPEG fallback is for software outside the browser: some older desktop applications, some email clients and a fair number of upload forms still refuse it. Do not use WebP for a file you are about to submit to a government portal.
Common questions
Does WebP lose quality?
In lossy mode, yes, in the same way JPEG does, but it discards less for the same file size. In lossless mode nothing is lost at all. Pick lossless if the source was a PNG you care about.
Can I convert WebP back to JPG?
Yes, on the convert to JPG page. Bear in mind that going back and forth between lossy formats degrades the image each time.
Will this work in every browser?
Encoding depends on the browser's own WebP support. If yours cannot do it, the tool will say so rather than silently producing a PNG.
