Why use WebP on your website?
Smaller images mean faster page loads, better Core Web Vitals and lower bandwidth bills. Every current browser supports WebP, so there is rarely a reason to keep serving large PNGs for photos and illustrations.
Frequently asked questions
Are my photos uploaded to your server?
No. The conversion runs entirely inside your browser using your own device. Your files are never sent to us or to any third party, which is why it also works for private photos and large batches. Once the page has finished loading you can even switch off your internet connection and the tool keeps working.
Is WebP supported everywhere?
All current versions of Chrome, Edge, Firefox and Safari display WebP. Some older desktop software and upload forms still do not accept it.
