WEBP Converter

WEBP is Google's web image format, smaller than both JPG and PNG at comparable quality and supported by every current browser. Its weakness is outside the browser, where plenty of desktop software and print workflows still cannot open it.

WEBP questions

Is WEBP better than JPG and PNG?

On file size, yes: roughly 25 to 35% smaller than JPG at matching quality, and smaller than PNG for lossless images with transparency. It is worse on compatibility outside the browser, where plenty of desktop software and older phones still refuse it.

Why will my WEBP not open in Photoshop or Windows Photo Viewer?

WEBP support outside browsers arrived late and unevenly. Photoshop added it natively in 2022 and older versions need a plugin; some Windows and Office builds still cannot read it. Converting to JPG or PNG is quicker than chasing a plugin.

Can WEBP do both lossy and lossless?

Yes, and it picks per image. Lossy WEBP competes with JPG on photographs; lossless WEBP competes with PNG on graphics and keeps a full alpha channel. That is unusual — most formats do one or the other.

Does WEBP support animation?

Yes, and far better than GIF: full colour instead of 256, with much smaller files. Converting an animated GIF to WEBP typically cuts the size by more than half while keeping every frame.
