How to use
- Upload your image (PNG, JPG, WebP, or GIF).
- Choose a target format — WebP for the web, or PNG/JPG to convert a WebP back.
- For WebP and JPG, drag the quality slider to trade size against detail.
- The before/after panel shows how much smaller (or larger) the result is.
- Click Download to save the converted image.
Why WebP
WebP was built for the web. At matching visual quality it’s typically 25–35% smaller than JPG and much smaller than PNG, and unlike JPG it supports transparency. Smaller images mean faster page loads and better Core Web Vitals — which is why WebP is now widely used across the web.
Converting back to PNG or JPG
Not everything reads WebP yet. Some older apps, email clients, and upload forms still expect PNG or JPG. Upload your WebP and pick:
- PNG — lossless, keeps transparency. Best for graphics and screenshots.
- JPG — smallest, no transparency. Transparent pixels are filled with the background colour you choose.
Private by design
The image is decoded and re-encoded locally in your browser through the canvas API. It’s never uploaded, so the conversion is instant and your files stay private.
