About this website
This website has been developed to demonstrate capabilities and features of HEIF.
The entire website uses only the NOKIA HEIF library to handle all HEIF files. No native "<img>", but processing and extracting data from files with the JS/WASM build of the library. Image dimensions: 1440x960, file size: 287 KiB
About HEIF
HEIF is an ISOBMFF based container format for storage of encoded media.
Supports codecs like AVC and HEVC - along with VVC, the latest codec in the family, to provide high quality media with good compression ratio. Image dimensions: 1440x960, file size: 127 KiB
Multiple Images, One File
HEIF can store bursts, collections, and animations in a single container — no zips, no sidecar files. Every frame shares the same metadata and codec efficiency.
Image dimensions: 1440x960, file size: 40 KiB
Non-Destructive Editing Built In
Grids, overlays, rotations, and crops are expressed as lightweight references — the original pixels are never touched. Alpha planes and depth maps ride alongside the primary image.
