Frequently asked questions
Is WebP supported everywhere?
Every modern browser (Chrome, Safari, Firefox, Edge) supports WebP. Some older desktop software and email apps don't, so keep your JPG originals too.

Yes. WordPress 5.8 and newer lets you upload WebP images to the media library like any JPG or PNG.
Are my images uploaded?
No. The conversion happens in your browser on your own device, so your images never leave it.
Can I convert many images at once?
Yes. Add as many as you like and download them one by one or all together as a ZIP file.
