Upload a JPG or PNG, convert it to WebP, and see the file size savings before you download.
WebP is a modern image format that produces smaller files than JPG or PNG at the same visual quality — which means faster page loads. This tool converts your JPG or PNG to WebP and shows you exactly how much space you save.
Step 1 — Upload a JPG or PNG.
Step 2 — Review the size comparison shown automatically.
Step 3 — Download the WebP file.

Yes — WebP typically achieves the same visual quality at 25-35% smaller file size.
