You encountered an AVIF image on the web or saved one from a modern website. AVIF produces smaller files than both WebP and JPG at equivalent visual quality, making it the most efficient image format currently available for web delivery.
AVIF is derived from the AV1 video codec, developed by the Alliance for Open Media (Amazon, Apple, Google, Meta, Microsoft, Netflix). It supports lossy and lossless compression, transparency, HDR, and wide colour gamuts. Chrome, Firefox, and Safari all render AVIF natively. The main limitation is encoding speed — AVIF takes significantly longer to compress than JPG or WebP, which matters for real-time applications but not for static assets.
Modern browsers display AVIF without issues. GIMP 2.10+ can open and export AVIF files. For converting images to AVIF format, tools like Squoosh (Google's web-based compressor) and libavif handle the job. If you need maximum compatibility, use JPG or WebP. If you're optimising web performance and your audience uses modern browsers, AVIF delivers the best quality-to-size ratio available.
