Why Are Images Saving as WebP?

If an image saves as .webp, the website most likely delivered a WebP file to your browser. Chrome is not simply changing every downloaded image to WebP by default. A site's server or page markup can choose a supported format based on the image source and the browser's request.

What Is WebP?

WebP is an image format developed by Google. It supports both lossy and lossless compression, transparency, and animation. Sites often use it to reduce transfer size, but the result depends on how the particular image was encoded; WebP is not automatically smaller or higher quality in every case.

If compatibility is not a problem and you only need to view the download, follow the device and browser options for opening a WebP file.

Why the Filename May Be Confusing

A page can use responsive image markup or content negotiation to send different formats to different browsers. A media URL may even end in .jpg while the server response contains WebP data. When you choose Save image as, the browser saves the representation it received.

Changing only the filename extension does not convert the image. Renaming photo.webp to photo.jpg can leave you with WebP data that some apps still cannot open.

Convert WebP to JPG or PNG

Choose the output based on what the receiving app needs:

• Use WebP to JPG for a broadly compatible photo file. JPG does not support transparency.
• Use WebP to PNG when you need transparency or a PNG workflow.

Conversion changes the file encoding. It cannot restore detail already removed by lossy compression, and converting to PNG does not make a previously lossy image lossless again.

You can also open the WebP file in an editor that supports it and export to the required format. Avoid uploading private images to an unfamiliar converter; review how a service processes and retains files first.

Can You Stop Chrome From Saving WebP?

There is no general Chrome setting that forces every site to send JPG or PNG. The reliable options are to download an alternative format offered by the site, take the original file from its source, or convert the downloaded WebP afterward. Browser extensions can modify downloads, but they add another party to the workflow and should be reviewed before installation.

Is WebP Better Than JPG?

Neither format is always better. WebP can offer efficient compression and transparency, while JPG remains widely compatible and works well for photographs. Compare visual quality, file size, transparency needs, and the requirements of the app or website receiving the file.

The key distinction is that the website chooses what to serve and the browser saves what it received. Convert the file when your next tool needs a different format; do not rely on renaming the extension.
