How it works
Your image is decoded and re-encoded as WebP at the quality level you choose, right in your browser, and you can compare the before and after size immediately.
Your image is never uploaded — the conversion runs entirely on your device.
Frequently asked questions
- Do all browsers support WebP?
- Yes — every modern browser (Chrome, Firefox, Safari, Edge) has supported WebP for years, so it's safe to use for websites and most sharing.
- Is WebP always smaller than JPEG?
- Usually, at equivalent visual quality, but not always for every image. This tool shows you the actual before/after size so you can decide.
- Can I convert back to JPEG later?
- Yes, though converting formats repeatedly can compound quality loss — it's best to keep an original copy of your source image.
