What is a .AVIF file?
AVIF is a next-generation image format based on the AV1 video codec, with excellent compression and HDR support.
- Did you know
- AVIF arrived in 2019, built on the royalty-free AV1 codec from the Alliance for Open Media.
- An AVIF image is essentially a single AV1 video keyframe stored inside a HEIF container, reusing the codec’s intra-frame compression for stills.
- AV1, and therefore AVIF, comes from the Alliance for Open Media, a consortium including Google, Apple, Microsoft, Netflix, Amazon, Meta and Mozilla.
- Because it inherits AV1’s tools, AVIF supports high dynamic range, wide colour gamut and transparency, and is often around half the size of an equivalent JPEG.
- On the web a .AVIF file is served with the MIME type
image/avif.
- 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 .AVIF file
- Drag a .AVIF 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.
