Free JFIF to WebP converter online

Need a WebP instead of a JFIF? This free converter turns JFIF files into WebP images right in your browser. Add as many files as you like, adjust the settings and download the results individually or together as a ZIP.

JFIF is really a JPEG image saved with the .jfif extension. Windows and some browsers save images from the web this way, and many websites, printers and apps then refuse to open them. Converting fixes the extension and the compatibility problem.

WebP is a modern format created by Google for the web. It is typically 25 to 35 percent smaller than an equivalent JPG and supports transparency and animation, which is why so many websites now serve it. The downside is compatibility: older versions of Photoshop, Windows Photo Viewer, many printers and lots of upload forms still cannot open WebP files.

Why convert JFIF to WebP?

  • WebP files are much smaller than JPG and PNG at the same visual quality, which makes web pages load faster and improves Core Web Vitals and SEO.
  • JFIF files are often rejected or can't be opened by upload forms and apps that only look for .jpg or .jpeg; WebP avoids that problem.
