How to convert JFIF to PNG
- Choose or drop one or more JFIF files above.
- Conversion starts right away. Resize first if you need different dimensions.
- Download each PNG, or save them all as a ZIP.
What is a JFIF file?
JFIF stands for JPEG File Interchange Format. A .jfif file is a JPEG photo with a different ending. Some browsers and apps save images this way, and Windows often does not open them in common programs, which is why people search for a converter.
Why convert to PNG?
- PNG is accepted by almost every editor, web form and document tool.
- PNG is lossless, so further edits and saves add no new quality loss.
- PNG supports transparency if you edit the image later.
What to expect
The pixels are copied exactly, so the picture looks the same. The file gets bigger, because a JPEG photo saved as PNG usually grows several times. If you only need an ordinary image file and size matters, use the JFIF to JPG converter instead, which keeps the file small.
Batch and size tips
Select several files at once and download one ZIP. If a PNG is too large for an upload, resize it first, or convert to a smaller format with the PNG to JPG converter. To learn how the formats differ, read the guide on JPG vs PNG.
Privacy, speed and file names
Every JFIF file is opened and saved as PNG inside your browser, so nothing is uploaded and conversion starts right away. Speed depends on your device, not your connection. Results are named after the original with “-tech9pros” added, so your originals are never overwritten. The picture inside a JFIF file is a normal JPEG, so any JPEG-based file also works.
Converting many files
Select up to 30 files at once and download them one by one or as a single ZIP. If you change a setting, the files are converted again with the new value, so you can try a different quality without adding them again.
If something goes wrong
If a file will not open, check that it is really an image and not renamed. Renaming a document to .jfif does not turn it into a picture.
Frequently asked questions
Is JFIF the same as JPG?
Yes. A JFIF file is a JPEG image. You can usually rename it to .jpg and it will open, or convert it here.
Why is the PNG so much bigger?
PNG stores every pixel without lossy compression. Photos saved as PNG are often five to ten times larger than the JPEG.
Does converting JFIF to PNG lose quality?
No new loss happens. The PNG matches the picture exactly, though it cannot restore detail the JPEG already lost.
