Hello! Thank you for your interest in our product. We are currently working on adding support for the AVIF file format to Aspose.Imaging. The upcoming releases will initially include the ability to load AVIF images for processing and export to other supported image formats. The feature to export other images into the AVIF file format is planned to be released later this year, a few releases after the initial AVIF support.
