Image compression is the process of downsizing an image as much as possible without sacrificing quality so that it can be stored at a lower cost and accessed more quickly.
CI launched the AVIF compression feature. It converts images to the .avif format, which is a new image format launched by Netflix based on AV1 in February 2020 and currently is supported by browsers such as Chrome and Firefox.
Restrictions
Format: Images in JPG, PNG, BMP, GIF, WebP, TPG, HEIF, or other formats can be converted into AVIF.
Size: The input image cannot be larger than 32 MB, with its width and height not exceeding 30,000 pixels, and the total number of pixels not exceeding 250 million. The width and height of the output image cannot exceed 9,999 pixels. For an input animated image, the total number of pixels (Width x Height x Number of frames) cannot exceed 250 million pixels.
Number of frames (for animated images): For GIF, the number of frames cannot exceed 300.
Prerequisites
To use AVIF compression, enable the image advanced compression feature for your bucket on the bucket's configuration page. For more information, see Image Advanced Compression.
Directions
CI uses the imageMogr2 API to provide the AVIF compression feature.
An image can be processed:

Upon upload
In cloud
Note:
AVIF compression is billed at image advanced compression prices. For detailed pricing, see Image Processing Fees.
When this feature is used by a sub-account, relevant permissions must be granted as instructed in Authorization Granularity Details.
