WebP Converter online
WebP produces noticeably smaller files than JPG or PNG at the same visual quality, which makes it excellent for websites. It is also the format you cannot open in older software — so this tool converts both ways.

Frequently asked questions
How much smaller is WebP?
For photographs, typically 25–35% smaller than a JPG of comparable quality. Against PNG the difference is far larger — often 60–80% — because PNG stores every pixel exactly.
Does WebP support transparency?
Yes, which is what makes it a genuine replacement for PNG rather than just for JPG. Transparent areas are preserved when converting from PNG.
Will WebP images work everywhere?
Every current browser displays WebP, so it is safe for websites. Older desktop software and some photo printers still do not accept it — convert back to JPG for those.
Why can't I convert to WebP?
A small number of older browsers can display WebP but not create it. If the option is unavailable, the tool falls back to JPEG and tells you.
Are my images uploaded?
No. Conversion runs in your browser and nothing is transmitted.
