How to convert AVIF to GIF offline

Choose local AVIF image files, choose "GIF" as target image format, then click the "CONVERT OFFLINE" button to start offline conversions in bulk. File size can be up to 2GB.

This offline converter will try to use canvas in web browser to convert images first. The image format depends on whether your current web browser supports. For example: the latest Chrome browser supports AVIF images while some old versions don't. Then the offline converter will try to use JavaScript to convert images if your current web browser doesn't support the image format.

Introduction	AV1 Image File Format (AVIF) is an image file format specification for storing images or image sequences compressed with AV1 in the HEIF file format. It competes with HEIC which uses the same container format, built upon ISOBMFF, but HEVC for compression. Version 1.0.0 of the AVIF specification was finalized in February 2019.	The Graphics Interchange Format (better known by its acronym GIF) is a bitmap image format that was introduced by CompuServe in 1987 and has since come into widespread usage on the World Wide Web due to its wide support and portability.
