Windows and some browsers save images with a .jfif extension, which many websites and apps reject. It's the same kind of image as JPG, and this tool gives you a standard .jpg file in one click.
How to use the JFIF to JPG tool
- Choose or drop your images. You can convert several at once.
- Adjust quality if the output format supports it (JPG and WebP).
- Download the converted files.
Frequently asked questions
Can I just rename .jfif to .jpg?
Usually, yes. They're the same format. Converting here guarantees a clean, standard JPG that every upload form accepts.
Is the conversion done online?
The page is online, but the conversion isn't. Your browser decodes and re-encodes the image locally, and no file is sent anywhere.
Does converting lose quality?
Converting to PNG is lossless. JPG and WebP are lossy, but at the default 92% quality the difference is very hard to see. Lower the slider for smaller files.
What happens to transparency?
PNG and WebP keep transparency. JPG can't store it, so transparent pixels are filled with white.
Is there a file size or count limit?
There's no fixed limit. Very large images (more than about 50 megapixels) may be slow or fail on phones with little memory.
