Select an image with the browse button, or drag and drop it onto the drop zone.
The image opens in the built-in editor running locally in your browser.
Optionally crop, resize, or fine-tune the image before exporting it.
Click Save to download the converted WebP file straight to your device.
WebP was designed for the web, and it shows: at comparable visual quality it typically produces noticeably smaller files than JPG or PNG. Smaller images mean faster page loads, better Core Web Vitals scores, and less bandwidth for your visitors, which is why converting site assets to WebP is one of the easiest performance wins available.
Site owners use this tool to shrink hero images, product photos, and blog graphics before uploading them to a CMS. It is equally useful in the other direction of scale: converting a folder-clogging collection of large PNG mockups into lightweight WebP copies for sharing. The conversion itself happens entirely inside your browser, one image at a time.

It depends on the content, but photographic images converted from PNG often shrink dramatically, and JPG sources usually get meaningfully smaller at similar quality. Images that are already heavily compressed will see more modest gains.
All modern browsers, including Chrome, Firefox, Safari, and Edge, display WebP without issues. Some older desktop software and legacy systems still lack support, so keep a JPG or PNG copy if you need to open the file in older tools.
Yes. WebP handles alpha transparency, so transparent areas from a PNG or SVG source are preserved in the converted file, usually at a much smaller size than the PNG equivalent.
