How AVIF Works
Using the AOMedia Video 1 (AV1) codec, originally developed for video streams, AVIF efficiently compresses both still and motion pictures. High-quality image storage is achieved in the AVIF format through the use of the High Efficiency Image File (HEIF) framework, offering an array of functions that include support for high dynamic range (HDR), as well as options for both lossless and lossy compression techniques.
The following points outline key attributes of the AVIF format:
- It gained standardisation within ISO/IEC 23000-22 in July 2020
- Progressive rendering from top-to-bottom isn’t supported by this format
- Despite this limitation, it excels at delivering images with exceptional quality
How WebP Works
The WebP file format utilises the VP8 video codec as its foundation for reducing image size and employs predictive coding for lossy compression. This method predicts blocks of pixels using information from others, resulting in a 30% smaller file size when compared to jpeg images without sacrificing significant image quality.
WebP can perform lossless compression by reconstructing new pixels through fragments of the image that have already been processed.
An alpha channel or transparency is supported within the WebP format. This feature allows for both lossy and lossless options. The architecture of the WebP container is constructed on RIFF (Resource Interchange File Format), which effectively segments data into manageable chunks.
How Do They Compare?
When comparing AVIF with WebP, various distinct characteristics emerge. One notable advantage of AVIF is that it can reduce file size by up to 50% more than WebP without sacrificing the integrity of image quality. Unlike WebP, which is limited to processing just 8-bit images, AVIF supports a wider range including 8, 10 and 12-bit images thereby enhancing quality due to an increased color depth.
In terms of compression techniques, while WebP accommodates both lossy and lossless compression, giving users the option to balance between image fidelity and file size efficiency. AVIF’s design leans towards preserving high-fidelity in images.
Though currently less prevalent compared to the widely integrated WebP format on online platforms, AVIFS holds potential for future use given its advanced capabilities in compressing files effectively while maintaining superior image quality standards.
