Frequently asked questions

How do I convert JFIF to PNG?: Upload your JFIF file above and it is converted to PNG automatically. Then click Download. No software to install — it runs in your browser and on our server.
How do I open a JFIF file?: JFIF files often won't open in an ordinary photo viewer without specialist software. The quickest way to open one is to convert JFIF to PNG here — upload your file and download a standard PNG that opens on any phone, computer or browser.
Can I use this as a JFIF file viewer?: Yes — it doubles as a free online JFIF viewer. Upload your file and the converted PNG is displayed right in your browser, so you can see the image without installing a JFIF viewer or codec pack. Download the PNG if you want to keep it.
What is a JFIF file?: JFIF is essentially a JPEG saved with a .jfif extension — the same image data as a .jpg, but the unusual extension stops some apps from opening it. Converting JFIF to PNG gives you a file that opens everywhere.
Is the JFIF to PNG converter free?: Yes — it is free to preview; create a free account to download. Premium adds batch conversion (many files into one ZIP) and larger uploads.
