AVIF (AV1 Image File Format)
The royalty-free successor to WebP, offering the world's best compression for the web.
AVIF is the cutting-edge image format derived from the AV1 video codec. Developed by the Alliance for Open Media (AOMedia)—a consortium including Google, Netflix, Amazon, and Microsoft—it was designed to be the ultimate royalty-free format for the web. AVIF offers significantly better compression than WebP, which was already better than JPEG. It supports features that WebP lacks, such as 10-bit and 12-bit color depth for HDR (High Dynamic Range) images, and it produces fewer compression artifacts at low bitrates. While encoding AVIF files takes longer than other formats, the bandwidth savings are substantial, often reducing file sizes by 50% compared to JPEG.
AVIF uses the HEIF (High Efficiency Image File Format) container structure but encodes the image data using the AV1 video codec. This allows it to use advanced video compression techniques like intra-frame prediction to squeeze image data down to incredibly small sizes. Unlike WebP, which is limited to 8-bit color, AVIF supports 10-bit and 12-bit color depths, making it the first viable web format for HDR photography. It also supports 4:2:0, 4:2:2, and 4:4:4 chroma subsampling, allowing for sharp text and graphics even with lossy compression.
The AV1 video codec was released in 2018 as a royalty-free alternative to HEVC (H.265). The AVIF image format specification followed in 2019. Adoption was rapid compared to previous formats. Chrome added support in 2020, followed by Firefox in 2021. Apple added support in iOS 16 and macOS Ventura (2022), completing the 'universal support' puzzle much faster than WebP did.
Photoshop Big
The 'Large Document Format' for managing gigapixel images.
PSB (Photoshop Big) is an extension of the PSD format designed to break the barriers of the 2GB file size limit and 30,000 pixel dimension limit of standard PSD files. It is structurally almost identical to PSD but uses 64-bit offsets inside the file to support massive files up to 4 Exabytes (theoretically) and 300,000 pixels in width/height.
Internally, a PSB file mirrors the block structure of a PSD (Header, Color Mode, Image Resources, Layer and Mask Info, Image Data). The key difference is the bit-width of length integers; PSB uses 8 bytes (64-bit) where PSD uses 4 bytes (32-bit) for describing file offsets and dimensions.
Introduced in Adobe Photoshop CS (v8.0) in 2003 to support the growing needs of astronomical imaging, billboard printing, and HDR photography.
