Why WebP for websites
WebP files are usually 25 to 35 percent smaller than a JPG of similar quality and much smaller than PNG for photos, while still supporting transparency. Smaller images load faster and help page speed scores. Every current version of Chrome, Edge, Firefox and Safari can show WebP.
Getting the smallest files
The biggest saving usually comes from the image dimensions, not the format. A 4000 pixel photo shown in a 1200 pixel column wastes most of its bytes. Turn on Shrink large images and pick a size close to how large the image is displayed, then adjust quality.
The results list shows original size, new size and the percentage saved for each file, plus a total for the whole batch.
Limits
- Animated GIFs become a still image of the first frame.
- Encoding uses your browser's built-in WebP encoder. Very old Safari versions (before 14) cannot create WebP and will show an error.
- Images are never uploaded. Very large files depend on device memory.
