About this tool
JPG photos converted to WebP are usually 25-35% smaller with no visible difference, which is why Google PageSpeed nags site owners to "serve images in next-gen formats". Convert your photos here, upload the WebP versions, and the warning goes away.
About the formats: JPG (JPEG) is a lossy format built for photographs. It compresses aggressively, produces small files, and opens on every device ever made, but it cannot store transparency and each re-save costs a little quality. WebP is Google's modern web image format. It supports both lossy and lossless compression plus transparency, and typically comes out 25-35% smaller than an equivalent JPG or PNG. Every current browser displays it, but some older desktop apps and upload forms still reject it.

Questions
Do all browsers support WebP?
Yes. Chrome, Edge, Firefox, Safari (since 14), and every modern mobile browser display WebP.
What quality should I use?
