How to Open a WebP Image on Windows or Mac and Convert a Copy

WebP is common on the web, but some desktop workflows still expect JPG or PNG. Convert the data, not just the filename.

WebP was designed for efficient web images and is widely supported in current browsers. Friction appears when an older desktop application, upload form, print workflow, or editing pipeline expects JPEG or PNG instead.

The easiest viewer is often your browser

Drag a WebP file into a current browser window or use an image viewer that supports the format. If you only need to inspect the picture, no conversion is necessary. Convert only when the next application requires another format.

  3. Select an export formatChoose PNG for transparency or JPG for broad photo compatibility.

For a deeper format comparison, read WebP vs JPG vs PNG. If the converted file exceeds an upload limit, use Compress afterward.
