Free JFIF to PNG converter online
Need a PNG instead of a JFIF? This free converter turns JFIF files into PNG 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.
PNG is a lossless format: it never throws image data away, so text and sharp edges stay crisp and it supports full transparency. The trade-off is file size: a photo saved as PNG is often 5 to 10 times bigger than the same photo as JPG. PNG files can hold hidden text chunks with software names, authors and dates.
