FAQ
Are my files uploaded to a server?
No. The conversion runs entirely in your browser using the Canvas API. Nothing is sent over the network.
How much smaller will the files be?
Usually 25–35% smaller than the JPG at comparable quality. The exact saving depends on the image content and the quality you pick.
Is transparency preserved for PNG?
Yes. WebP supports an alpha channel, so transparent PNG areas stay transparent.
Which browsers open WebP?
All modern browsers: Chrome, Firefox, Safari 14+, Edge and Opera. Very old software may not display it.
Can I convert several files at once?
Yes. Drop as many files as you like; they are converted one by one and you can download them all as a ZIP.
