Frequently asked questions
What is a JFIF file?
JFIF stands for JPEG File Interchange Format. It is basically the standard JPEG format but with a specific file header. Many web browsers save images as JFIF instead of JPG, which causes confusion when other apps don't recognize the .jfif extension.
Is the conversion from JFIF to PNG lossless?
Yes. The output PNG is completely lossless. The conversion simply takes the pixel data from the JFIF file and stores it uncompressed in the PNG format without introducing any new quality loss.
Are my JFIF files sent to a server for conversion?
No. All conversion is handled directly on your device using the Canvas API in your browser. Your images are never uploaded to our servers, ensuring your privacy.
Why not just rename the .jfif extension to .jpg?
While renaming sometimes works because the underlying data is JPEG, converting the file to PNG provides a true format shift that guarantees 100% compatibility, especially if you intend to edit the image, remove its background, or upload it to strict systems.
Can I convert multiple JFIF images at once?
Yes. You can select up to 30 JFIF files at a time. The converter will process them in one batch and you can download them individually or as a ZIP file.
