Frequently asked questions
What is a JFIF file?
JFIF is a JPEG variant that Windows sometimes uses when saving images. Most apps expect a .jpg extension, so converting to PNG fixes the problem permanently.
Will I lose quality converting JFIF to PNG?
No — PNG is a lossless format, so every pixel of your original image is preserved in the conversion.
Can I batch convert JFIF files?
Yes — convert up to 10 JFIF files per batch (5 MB each), and run as many batches as you like.
Why will my JFIF not open in some apps?
Some software only recognises the .jpg extension. Converting to PNG — or using our image converter for other formats — solves it for good.
