How this converter works
Your browser already knows how to read WebP; what it lacks is a button to save the image as something else. This tool is that button. It decodes each WebP locally with the browser's own image engine, redraws it on a canvas, and exports a JPG at the quality you pick. Nothing is uploaded, which is also why it is fast: a 5 MB image converts in well under a second, and a folder of files converts as a batch.
When JPG is the right choice
JPG is the format everything accepts: old software, government forms, marketplaces, email clients from 2009. Convert to JPG when compatibility is the goal and the image is a photo. Keep in mind JPG has no transparency: transparent areas become white. If your WebP has transparency you want to keep, use our WebP to PNG converter instead.
Why WebP files exist at all
WebP is Google's web format: 25 to 35 percent smaller than JPG at the same quality, which is why sites serve it and why right-clicking an image so often saves a .webp you did not ask for. It is a good format for the web and an annoying one everywhere else. Converting a copy for the tool that refuses it is the practical fix.
