A .jfif file is a JPEG in disguise. Rename it to .jpg, or open it in Paint or Preview and save as JPG or PNG. Here are the exact steps and why images end up as JFIF.
A .jfif file is a JPEG image, so the quickest way to convert it is to rename the extension to .jpg; to get a PNG, open it in Paint or Preview and save it as PNG. JFIF stands for JPEG File Interchange Format, and it holds the same kind of compressed photo data as a normal .jpg file.

Why Did My Image Save as .jfif?
Some combinations of Windows and web browsers save pictures downloaded from the web with the .jfif extension. Nothing is wrong with the picture. It is a JPEG, but some apps, upload forms and editors do not recognise the .jfif extension and reject it.
How to Convert JFIF to JPG
- Rename it. In File Explorer, click the file, press F2, and change .jfif to .jpg. If you cannot see extensions, open the View menu and tick File name extensions.
- Or save a copy. Open the file in Paint, Photos or Preview, choose Save As and select JPEG.
Renaming is safe for JFIF because the content is already JPEG. It does not work for other formats: renaming a TIFF or WebP to .jpg breaks it.
How to Convert JFIF to PNG
Windows (Paint): right-click the file, choose Open with, then Paint. Choose File → Save as → PNG picture.
Mac (Preview): open the file in Preview, choose File → Export, set Format to PNG and save. If Preview does not open it, rename the file to .jpg first.
Converting to PNG does not improve quality. The picture already lost its fine detail when it was first compressed as JPEG, and the PNG copy is usually much larger. Only convert to PNG when a site or program requires it, or when you need transparency later.
Convert It Online Instead
You can also convert in your browser with the free imgmend converters: JFIF to JPG or JFIF to PNG. Nothing is uploaded, and you can convert up to 20 files at once.
If the File Is Too Big After Converting
PNG copies of photos can be several times larger than the JPEG. To shrink an image, use the imgmend compressor, which lowers quality and dimensions in your browser and shows the new size before you download. If the upload is rejected because of the .jfif extension, rename the file to .jpg first.
Which Format Should You Use?
For photos, keep JPG. Use PNG for graphics, screenshots and anything that needs transparency. For the trade-offs, see PNG vs JPEG and JPG vs JPEG.
Frequently Asked Questions
Is JFIF the same as JPG?
Yes. JFIF is a JPEG file format, so a .jfif file holds a normal JPEG image.
How do I convert JFIF to PNG?
Open the file in Paint or Preview and save it as PNG. The picture will look the same; only the file type changes.
Can I just rename .jfif to .jpg?
Yes, for a real JFIF file. Renaming works because the content is already JPEG.
Does converting JFIF reduce quality?
Renaming or saving as PNG does not reduce quality. Saving again as JPG at a lower quality setting does.
