Why convert JFIF to PNG?
- PNG is supported far more widely than JFIF, so the file is easier to open, share and upload.
- PNG is lossless, so the converted image loses no further detail when you edit and save it again.
- PNG is made for screenshots, logos, text graphics and cut-outs.
What to expect when converting JFIF to PNG
- Converting can’t bring back detail that JFIF compression already removed: the PNG is an exact copy of the image as it is, usually in a bigger file.
- Your original JFIF file isn’t changed: you download a new PNG copy.
