Attempt to convert AVIF images to HEIF directly in your browser. HEIF/HEIC encoding support is experimental and limited to specific browsers and platforms.
Most browsers today can decode HEIF/HEIC, but almost none expose an image/heif encoder via canvas. This tool will try image/heif and then image/heic; if your browser doesn’t support them, conversion will fail for that file. In that case, export to JPG/PNG first and use a native HEIF/HEIC encoder on your device.
Drag and drop your AVIF images here, or click to browse from your device.
Supports multiple AVIF files • All processing happens locally in your browser, where supported.
HEIF is the container format behind HEIC on Apple devices. In everyday workflows the terms overlap, but technically HEIF can hold different codecs, including HEVC (HEIC) or even AV1. Browser‑side encoding is not standardized yet, so treat this tool as an experimental bridge: if your browser exposes HEIF/HEIC encoders, you can export directly; otherwise, keep using our AVIF → JPG/PNG tools and a native encoder for production‑critical tasks.
