About this tool
JFIF files are JPEG images saved with a .jfif extension, common when downloading pictures from some browsers and apps; many programs do not recognize the extension. This tool opens the file in your browser and saves a lossless PNG (jfif-to-png.png) at the same pixel size. The conversion fixes the compatibility problem, but it does not improve the picture: JPEG compression already lost detail. PNG files from photographs are usually much larger. If you just need a widely supported image with a small size, JFIF to WebP or simply renaming to .jpg may suit you better. Everything runs in your browser; the file is not uploaded.
How to use it
- Drop a .jfif or JPEG file or choose one.
- Wait for the preview.
- Check the size shown.
- Press Download.
Common problems
- PNG is much bigger
- PNG is lossless, so a photo grows. Choose WebP for a smaller file.
- File will not select
- The picker accepts .jfif and JPEG images. Rename an odd extension to .jpg.
- Expecting transparency
- The source JPEG has none, so the PNG will be fully opaque.
