Questions people ask
Why convert images to WebP?
WebP images are usually 25 to 35% smaller than JPG and often much smaller than PNG at a similar quality. Smaller images make pages load faster, which helps visitors and search rankings.
Will transparency be kept?
Yes. WebP supports transparent backgrounds, so transparent PNGs stay transparent.
Do my images get uploaded?
No. Images are converted in your browser and never sent to a server.
Which browsers can create WebP files?
Chrome, Edge, Firefox and Opera. Safari can view WebP but can't create it, so use one of the other browsers for this tool.
Do I need an account?
No. Every tool marked In your browser works without signing up, and there is no watermark on the result.
Does it work on a phone?
Yes, in any modern mobile browser. Very large files are easier to handle on a computer because phones have less memory.
