What is a .HEIF file?
HEIF is the high-efficiency image format behind Apple’s HEIC, storing photos at higher quality and smaller size than JPEG.
- Did you know
- HEIF was finalised by MPEG in 2015 and is best known as the basis of Apple’s HEIC photos.
- HEIF is built on the ISO base media file format, the same container family that underpins MP4 video.
- A single HEIF file can hold a whole burst, an image sequence or a cinemagraph, not just one still.
- Beyond the picture itself, HEIF can carry depth maps, alpha channels and focus stacks as separate items in the same file.
- Although HEVC is its best-known codec, the HEIF container can also wrap AVC or even plain JPEG-coded images.
- 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 .HEIF file
- Drag a .HEIF 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.
