WebP Converter
Converts images to or from WebP, with a quality slider and lossless mode.
WebP is the format that is smaller than JPEG at the same visual quality and keeps transparency like a PNG, which makes it the right default for the web and the wrong one for anything a person will open on their computer. This converts both ways.
Lossy with transparency, and usually 25–35% under a JPEG of the same visual quality. Encoded by the browser, so what you get depends on the browser.

Drop images to convert
PNG, JPEG, WebP, GIF, BMP or AVIF in — whatever your browser can decode.
How to use it
Drop what you have
PNG, JPEG or WebP in; the target selector decides which direction you are going.
Set the quality against the readout
80 is a good default. WebP holds detail better than JPEG at the same number, so a setting that looks soft in JPEG is often fine here.
Check what the browser actually produced
The page probes for a WebP encoder on load, because a browser without one returns a PNG and says nothing about it.
Common questions
Is WebP safe to use now?
On the web, yes — every current browser decodes it. Outside the browser it is patchier: some desktop image viewers, older office software and a few phone galleries still refuse it, so a file you are sending to a person is safer as JPEG.
Lossless WebP or PNG?
Lossless WebP is usually smaller than PNG for the same pixels. PNG is the safer choice when the file leaves the web, and the PNG compressor here gets most of the difference back.
My converted file got bigger.
Converting an already-compressed JPEG to WebP re-encodes what is left after JPEG threw detail away, and the second encoder has to spend bits describing the first one’s artefacts. Convert from the original whenever you still have it.
