What is a JFIF file?

JFIF stands for JPEG File Interchange Format. A .jfif file holds a normal JPEG image; the difference is mostly in the file extension and a small header. Some programs, and some Windows setups when you save a picture from the web, produce .jfif files, but many apps, websites and print services only accept .jpg, .jpeg or .png. Converting the file solves that.

JFIF to JPG: do I lose quality?

Not with the default option. Because JFIF already contains JPEG data, "keep original quality" copies the image data as it is and gives it a .jpg extension, so there is no re-compression and no generation loss. If you choose "re-compress", the image is decoded and saved again as a JPG at the quality you select, which can make the file smaller but changes the pixels slightly.

JFIF to PNG

PNG output decodes the picture and saves it as a lossless PNG. The file is usually larger than the JPG and it does not add detail that was not in the original, but it is useful when a program requires PNG. JFIF images do not contain transparency, so the PNG will be opaque.

Other ways to open a JFIF file

You can often rename the file from .jfif to .jpg, or open it in an image viewer or browser. Converting with this tool is handy when you have many files, want a PNG, or an app refuses the .jfif extension.

Frequently Asked Questions

Is the JFIF to JPG converter free?
Yes. It is free to use, with no registration and no limit on how many files you convert.
What is a JFIF file?
JFIF (JPEG File Interchange Format) is a JPEG image with a .jfif extension. It contains standard JPEG picture data, so it is closely related to a .jpg file.
Are my images uploaded to a server?
No. The conversion runs in your browser using your device, and your files are not sent to our servers.
Does converting JFIF to JPG reduce quality?
Not with "keep original quality", which keeps the original JPEG data and only changes the extension. If you choose re-compress, the picture is saved again as a JPG and can change slightly depending on the quality you set.
Can I convert JFIF to PNG?
Yes. Choose PNG as the output format. PNG files are lossless but usually larger than JPG files.
Can I convert several JFIF files at once?
Yes. Add as many files as your device can handle, convert them together and download them individually or as one ZIP file.
Why do my pictures save as .jfif?
On some Windows setups, images saved from a web browser can be given a .jfif extension even though they are JPEG images. Converting or renaming the file to .jpg fixes compatibility problems.
Does it work on phones and tablets?
Yes, it works in modern mobile browsers. Very large batches may be slow on older devices.
