Common questions about AVIF
Why won't my image editor or older browser open my AVIF file? The format is still young, and support in desktop software lags well behind the major browsers — a conversion to JPG or PNG keeps the image editable.
Why convert images to AVIF? It is the smallest format today’s browsers accept, often half the size of JPG, with HDR and wide-colour support on top.
Which browsers open AVIF images? Current Chrome, Edge, Firefox and Safari display AVIF, while older browsers and many desktop photo viewers do not. Keeping a JPG or WebP copy alongside is the safe approach for a site that must work everywhere.
