DXT5 to AVIF

Useful information about DXT5

Extension: DXT5
Name: S3 Texture Compression - Dxt5
Mime Type: image/dxt
Converter: DXT5 Converter
Description: The DXT5 format is an alternate RGBA format. As in the DXT3 case, each 4x4 block takes up 128 bits. So it provides the same 4:1 compression as in the DXT3 case. Just as for the DXT3 format, there are two 64-bit chunks of data per block: an RGB chunk compressed as for DXT1 (with the same caveat as for DXT3), and an alpha chunk. Again the second chunk is the color chunk; the first is the alpha. Where DXT3 and DXT5 differ is how the alpha chunk is compressed. DXT5 compresses the alpha using a compression scheme similar to DXT1. The alpha data is stored as 2 8-bit alpha values, alpha0 and alpha1, followed by a 48-bit unsigned integer that describes how to combine these two reference alpha values to achieve the final alpha value. The 48-bit integer is also stored in little-endian order. The 48-bit unsigned integer contains 3-bit codes that describe how to compute the final alpha value. These codes are stored in the identical order as the codes in DXT1; they simply are 3 bits in size rather than 2. - Source

Useful information about AVIF

Extension: AVIF
Name: High Efficiency Image File
Mime Type: image/avif
Converter: AVIF Converter
Description: High Efficiency Image File Format (HEIF) is a container format for storing individual images and image sequences. The standard covers multimedia files that can also include other media streams, such as timed text, audio and video. HEIF can store images encoded with multiple coding formats, for example both SDR and HDR images. A HEIF image using HEVC requires less storage space than the equivalent quality JPEG. HEIF files are a special case of the ISO Base Media File Format (ISOBMFF, ISO/IEC 14496-12), first defined in 2001 as a shared part of MP4 and JPEG 2000. Introduced in 2015, it was developed by the Moving Picture Experts Group (MPEG) and is defined as Part 12 within the MPEG-H media suite (ISO/IEC 23008-12). - Source
