Following Google Chrome, Windows users are now able to process webP-formatted images through Mozilla Firefox. After installing the latest Firefox 72 Nightly Build, users can choose to open and view WebP-formatted images by default in that browser. In addition to Chrome and Firefox, modern browsers such as Microsoft Edge support WebP picture formats.

WebP supports lossy and lossless compression, with a higher compression ratio and a file volume reduction of more than 26% compared to traditional JPEG and PNG images.
Interestingly, while the picture viewer and Photos app that comes with Windows 10 doesn’t support webP, the Paint app does.
By installing a WebP codec provided by Google, users can view webP images natively in the picture viewer on Windows.
You can even open WebP images in a supported modern web browser, just note that Internet Explorer is not as advanced as Microsoft Edge.
Finally, if you’ve encountered a bug on Windows 10 1903 that doesn’t make Firefox the default WebP file processing app, refer to the following methods.
Go to ‘Settings – – apps – – default apps’;
Tap the file type and select the default app;
Find .webp and select ‘Firefox Nightly’ as the default handler.
