Convert a HEIC Image to AVIF Online
All processing happens in your browser — files never upload anywhere.
HEIC to AVIF converts your High Efficiency Image Container (.heic) files to AV1 Image File Format (.avif) directly in your browser using the browser's built-in Canvas 2D encoder. No signup, no watermark, no upload — your HEIC stays on your device from start to finish. AV1 Image File Format is typically used for next-gen web images (50% smaller than JPEG), and Toolspace's converter preserves the source at the highest quality the target format allows.
