Allow uploading AVIF files to Wikimedia sites (Community Wishlist/W8)

Description

The AVIF image format is supported by all modern web browsers now. It generally has better compression than JPEG and WebP. With this format, photographers can reduce photo size, or add photos with greater than 8-bit color. I hope Wikimedia sites can support uploading AVIF files.

Support Absolutely no reason not to support this given the level of compatibility in modern software. The glacial pace of WebP use in the wild is bracing, to be sure, but no matter the path to replacing JPEG as the default image format, we'll all be better off for having travelled it.

Support AVIF's generally smaller size and HDR support are major benefits. It would be great to pair this with <picture> elements for image thumbnails so that older browsers can fall back to whatever they support (WebP, PNG, etc.) - see phab:T343836. Qzekrom (talk) 04:48, 13 July 2026

Support Wanted to upload an animated AVIF, now I have to upload an bad quality and bigger GIF variant of it instead. Carrylex (talk) 16:24, 27 August 2026

Support I would prefer the JPEG XL standard but this would be a huge improvement nonetheless. Modern cameras have been capturing 14-bit color depth, modern displays can display >8-bit color, yet we have been stuck having to create images in 8-bit JPEG s.t. they can be published here. We have modern technology and modern standards and I do not want to develop pictures with artificially reduced color information. Trougnouf (talk) 17:49, 30 August 2026

Support See also the JPEG XL wish. My pictures illustrate 7000+ wiki articles, and I hope Commons will support JPEG XL or AVIF or both soon. Syced (talk) 04:47, 7 September 2026
