Frequently Asked Questions
What is a JFIF file?
JFIF (JPEG File Interchange Format) is a standard JPEG image. Windows uses the .jfif extension for some images saved from browsers.
How do I convert JFIF to PNG?
Upload the .jfif file, click Convert and download the PNG.
Why do my images save as JFIF?
A Windows registry setting maps the JPEG type to .jfif. The image itself is a normal JPEG.
Can I just rename .jfif to .jpg?
Usually yes, because it is a JPEG. Converting to PNG instead gives you a lossless copy for editing.
How do I stop Windows saving images as JFIF?
In the registry key HKEY_CLASSES_ROOT\MIME\Database\Content Type\image/jpeg, change the Extension value to .jpg. If you prefer not to edit the registry, just convert files here.
Does converting JFIF to PNG lose quality?
No. PNG is lossless, so the image is stored exactly as decoded.
Can I convert JFIF to JPG?
Use the Universal Image Converter and pick JPG.
Will the PNG be bigger?
Yes, PNG files are usually larger than JPEG for photos. That’s normal.
Can I upload JFIF to Instagram or forms?
Many sites reject .jfif; converting to PNG or JPG fixes that.
Does the JFIF to PNG tool store my image?
No, it is converted in memory and deleted immediately.
