About this tool

WebP typically encodes photos 20–35% smaller than JPG at comparable visual quality, which makes pages load faster and improves Core Web Vitals. This tool re-encodes your JPG locally and shows the original size, the new size and the percentage saved so you can judge whether the trade-off is worth it for each image. All modern browsers support WebP; only very old software does not.

Frequently asked questions

How much smaller will my images get?
It depends on the photo, but 20–35% smaller than the source JPG at similar quality is typical. The tool shows the exact saving for each file after conversion.
Is WebP safe to use on my website?
Yes. Every current browser supports WebP. If you must support very old browsers, keep a JPG fallback.
Does converting twice lose quality?
Each lossy re-encode discards a little detail. Convert from the highest-quality source you have rather than re-converting repeatedly.
