What is a .HEIC file?
HEIC (HEIF) is Apple’s high-efficiency image format used by iPhones, storing photos at higher quality and about half the size of JPEG.
- Did you know
- Apple adopted HEIC in 2017 with iOS 11, based on the MPEG HEIF standard finalised in 2015.
- HEIC is really a pairing of two things: the HEIF container, an ISO standard, holding images compressed with the HEVC, or H.265, video codec.
- A single HEIC file can bundle a Live Photo, a burst sequence, an alpha channel and even a depth map alongside the main picture.
- On iPhones, HEIC preserves 10-bit colour in the wide Display P3 gamut, holding more tonal information than an 8-bit JPEG can.
- On the web a .HEIC file is served with the MIME type
image/heic.
- 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 .HEIC file
- Drag a .HEIC 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.
