PNG to WebP
Convert PNG to modern WebP for smaller, faster web images. Runs in your browser.
Convert PNG to WebP entirely in your browser. The file is decoded and re-encoded on your own device using the browser's built-in image engine, so it is never uploaded to a server — useful for private screenshots, ID scans, or client work you would rather not send anywhere. There is no signup, no watermark, and no file-size limit beyond your device's memory.
PNG is lossless and supports transparency — best for graphics, logos, and screenshots. WebP is a modern web format, roughly 25–35% smaller than JPG/PNG at the same quality.

Why convert in your browser
Most online converters upload your image to a remote server, process it there, and send it back — which means your file sits on someone else's machine. This tool runs the whole conversion locally in your browser tab, so the image never leaves your device. There is no upload wait, no per-file size cap, and sensitive images stay private. Once the page has loaded, it even works offline.
Quick tips
- ✓Keep your original PNG. Converting does not delete it, and you may want to re-export at a different quality later.
- ✓For photos, quality around 80 is the sweet spot: visually identical to the original at a much smaller size.
- ✓WebP is a good fit when serving images on the web, where smaller files speed up your pages.
- ✓Converting does not change the pixel dimensions — only the format and file size. Use a resize tool first if you also need the image smaller.
- ✓Browser-based conversion usually strips EXIF metadata like GPS and camera info, which is often a privacy plus when sharing photos.
