Frequently asked questions
Converting JFIF to PNG is worth doing when you need what PNG offers: lossless and supports transparency. JFIF gives you its own strengths, but its drawback is some limitations.
How it works
- Add your JFIF files.
- The output format is already set to PNG.
- Adjust quality if the format supports it.
- Download the converted PNG files.
Good to know
One thing to keep in mind: larger files, especially for photographs. Converting does not repair damage already present in the source — if the JFIF was heavily compressed, those artefacts carry across into the PNG.
Frequently asked questions
Is converting JFIF to PNG lossless?
The PNG encoding itself is lossless, so nothing further is discarded. Any compression damage already baked into the JFIF remains, because conversion cannot undo it.
Why convert JFIF to PNG at all?
Usually for lossless and supports transparency. If neither of those matters for your use, keeping the JFIF is perfectly fine.
