VLC reads AVIF files starting with version 4, which is still in development.AVIF read support is present in IrfanView.However, Safari has not yet implemented it due to Safari's image decoding being handled by macOS and not directly by the WebKit browser engine. WebKit added AVIF support on 5 March 2021.It had planned to enable AVIF support by default in Firefox 86, but pulled the change a day before release. In October 2021, Mozilla Firefox 93 was released with default AVIF support.Google Chrome 89 for Android adds AVIF support.
In August 2020, Google Chrome version 85 was released with full AVIF support. In November 2020, HDR sample images with PQ transfer function and BT.2020 color primaries were published. On 14 December 2018 Netflix published the first. It is still possible to use the Advanced profile to create larger images using grid derivation. Coded image items compliant to the AVIF Advanced profile may not have a total number of pixels greater than 35651584, a width greater than 16384, or a height greater than 8704. It is still possible to use the Baseline profile to create larger images using grid derivation. More precisely, coded image items compliant to the AVIF Baseline profile may not have a total number of pixels greater than 8912896, a width greater than 8192, or a height greater than 4352. Level 5.1 is chosen for the Baseline profile to ensure that no single coded image exceeds 8K resolution, as some decoders may not be able to handle larger images. 4:2:0, 4:2:2, 4:4:4 chroma subsampling and RGBĪVIF specification defines two image profiles:. Monochrome (alpha/depth) or multi-components. 
Lossless compression and lossy compression.Color space signaling via CICP (ITU-T H.273 and ISO/IEC 23091-2) or ICC profiles.SDR (with sRGB / BT.709 / BT.601 or with wide color gamut).HDR (with PQ or HLG transfer functions and BT.2020 color primaries, as part of BT.2100).
