What is a .JFIF file?
JFIF (JPEG File Interchange Format) is a standard JPEG image variant, functionally the same as a .jpg file.
- Did you know
- JFIF was defined in 1992 to standardise exactly how JPEG image data is stored in a file.
- JFIF was led by Eric Hamilton of C-Cube Microsystems, with input from the Independent JPEG Group.
- It fixed the original JPEG standard’s gap by defining exactly how to store the compressed data in an actual file.
- JFIF pins down practical details such as the YCbCr colour space and a pixel aspect-ratio field.
- It can embed a small uncompressed thumbnail of the image right inside the header.
- What Analyser shows you
- View EXIF, GPS, camera settings, histograms, dominant colours, OCR text, and AI-generation markers in JPG, PNG, HEIC, WebP, GIF, BMP, TIFF, AVIF and JPEG XL images. Detects computational-photo wrappers (Apple Live Photo, Google and Samsung Motion Photo, Ultra HDR gain maps), opens THM movie-thumbnail files, and extracts every embedded image from multi-image files - all sizes in an ICO, both halves of an MPO stereo pair, and every page of a multi-page TIFF.
- Open a .JFIF file
- Drag a .JFIF file onto the Analyser home page (or tap to pick one). It opens entirely in your browser - nothing is uploaded, there is no account, and it works offline once installed.
