Hello.

Tell me why does the browser save the jpeg file as webp?

Ask the website. Despite the extension, they are serving the file as webp.

@aidar The internal file header renders it as a webp file, not a jpg file. Anyone can name any file with any extension type they want, but that doesn't make it that kind of file-type. In this case, someone at the site probably made a labeling mistake...

Try using this extension to override the "Accept" request header value for the site so that it's text/html,application/xhtml+xml,application/xml;q=0.9,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9 instead of text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,image/apng,*/*;q=0.8,application/signed-exchange;v=b3;q=0.9.

Notice image/webp missing in the former. This stops Opera from telling the site that it supports image/webp so that the site falls back to jpeg.

You might have to clear your cache first to get the updated result for the test pic you linked to.
