Why Convert JFIF to PNG?

JFIF is just a JPEG. The extension is the only thing standing between the file and an app that refuses it, and when that app expects a lossless PNG rather than a JPEG, converting straight from JFIF to PNG saves you a hop.

Pick this target when you plan to edit the image further, or when the place you're uploading to only takes PNG.

Frequently Asked Questions

Will the PNG be larger than the JFIF?
Almost always. PNG is lossless and stores the image less compactly than the JPEG data inside the JFIF, so a bigger file is normal. You gain a format that edits cleanly without re-compression.
Does the JFIF have transparency to preserve?
No. JFIF holds JPEG data, which has no alpha channel, so the PNG will have a solid background. PNG simply gives you a lossless container going forward.
JPG or PNG, which should I pick?
Pick JPG if you just need a widely accepted photo and a small file. Pick PNG if you will edit the image or need a lossless master for further work.
Why won't my app open the .jfif directly?
Most apps can read the data but block the unfamiliar extension at upload. Converting sidesteps that check by handing over a .png the tool recognizes.
Is my file still private in the desktop app?
Yes. The desktop app converts with native engines on your Mac and works offline after a one-time activation check. Nothing is uploaded, in the browser or on desktop.
