Frequently asked questions
What is WebP?
WebP is a modern image format that delivers much smaller files than PNG or JPG at the same visual quality — often 25 to 35 percent smaller than comparable JPEGs. It also supports transparency like PNG.
Do browsers support WebP?
Yes. All modern browsers — Chrome, Edge, Firefox, Safari, and Opera — display WebP images, on both desktop and mobile.
Is my image uploaded to a server?
No. The conversion runs entirely in your browser. Your images never leave your computer.
