HEIC vs AVIF: what changes when you convert
HEIC (High Efficiency Image Container) was introduced in 2017 by the MPEG group; adopted by Apple in iOS 11 and is best known for iPhone camera photos (half the size of JPG at the same quality). AVIF (AV1 Image File Format), created by the Alliance for Open Media (Google, Netflix, Mozilla), is the better choice when you need maximum web compression — typically 50% smaller than JPG.
Why convert? AVIF files are typically much smaller than HEIC — expect a noticeable reduction in file size. HEIC photos from an iPhone routinely fail to open on Windows PCs and Android phones. Converting to AVIF solves that instantly.
Upload one file or a whole batch — conversion happens over a secure HTTPS connection and finished files are automatically deleted from our servers within minutes. Most desktop image editors and older devices cannot open AVIF yet.
