How to convert HEIC to GIF offline
Choose local HEIC 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. Use online converter instead if this offline converter doesn't work in your web browser.

| Introduction | As HEIC is a container format, it can contain still images and image sequences (where a file contains more than one single image) that are coded in different formats. Currently, these include HEVC and H.264/MPEG-4 AVC (and JPEG for thumbnail/secondary images), though other coding formats may be added in the future. The main filename extension is .heic (for HEVC codec). | 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. |
