To convert JFIF to PNG, drop the .jfif file in, click Convert to PNG, and download the result. A JFIF file is just a JPEG with an unusual extension, and the PNG works in almost every app. It runs in your browser.
What is a JFIF file?
JFIF stands for JPEG File Interchange Format. It isn't really a separate image type. It's ordinary JPEG data saved with a .jfif extension, which some browsers do when you right-click a picture and choose Save Image As.
The picture is fine. The extension is what causes trouble, because many apps and upload forms don't recognize .jfif and reject the file.
How to convert JFIF to PNG
- Click Select File, or drag your .jfif file into the drop zone.
- Click Convert to PNG.
- Check the preview, then click Download to save the PNG.
Why PNG, and what about JPG?
PNG is recognized everywhere, and it's lossless, so saving it won't add more compression to what the JPEG already had. That helps if you plan to edit the image afterward.
The PNG will be larger than the JFIF. If you want a small, standard JPG instead, Image Converter can save it as JPG, and on many computers you can also just rename the extension from .jfif to .jpg. To keep the result compact, run it through Image Compressor.
Why does my browser save images as JFIF?
It's a quirk of certain browser versions, especially older Chrome and some Windows setups, and not something wrong with the image. Saving through a different method, or converting like this, gets you a normal file. For more on what these files are, see our image format guide.
How to stop downloading .jfif files
You can rename the extension from .jfif to .jpg on many computers, and the file will open normally. Windows may hide extensions by default, so turn on File name extensions in File Explorer's View menu first.
If the problem keeps coming back, try saving images from a different browser, or use the browser's copy image option and paste it into an editor.
Frequently asked questions
Is a JFIF file different from a JPEG?
Not in any way that matters. The picture data is standard JPEG, and only the file extension and a small header differ.
Why does my computer save pictures as .jfif?
Some browser versions and Windows setups label JPEG downloads that way. The image itself is unchanged.
Will the PNG be bigger than my JFIF?
Yes, usually. PNG uses lossless compression, which makes larger files than JPEG-based formats.
Can I convert JFIF to JPG instead?
Yes. Use Image Converter and pick JPG, or try PNG to JPG after converting.
Does it keep transparency?
A JFIF has no transparency to keep, so the PNG has a solid background.
Is my file uploaded?
No. It's converted on your device and never sent anywhere.
