Attempt to convert AVIF images to HEIC/HEIF directly in your browser. HEIC encoding support is experimental and limited to specific browsers and platforms.
Most browsers today can decode HEIC/HEIF, but almost none expose an image/heic encoder via canvas. This tool will try image/heic and image/heif; if your browser doesn’t support them, conversion will fail for that file. In that case, you can export to JPG/PNG first, then use a dedicated 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.
HEIC (HEIF) is widely used on iOS and macOS Photos, but browser‑side HEIC encoding is not standardized yet. This experimental tool checks what your browser can do: if it exposes an image/heic or image/heif encoder, you can generate HEIC files directly; otherwise, treat this as a capability tester and fall back to our AVIF → JPG/PNG tools plus an offline HEIC encoder. Your images never leave your device either way.
Try converting AVIF images to HEIC/HEIF format directly in your browser. Detect whether your browser supports HEIC encoding and generate HEIC files when possible, with no uploads.
HEIC is a modern image format used heavily on Apple devices, but browser-side HEIC encoding support is limited and experimental. This tool helps you explore what your current browser can do with AVIF → HEIC conversion.
An AVIF to HEIC converter attempts to transform AVIF images into HEIC/HEIF files directly in your browser. Because HEIC encoding is not widely exposed in web APIs, this tool acts both as a converter and a capability checker.
If your browser and operating system expose an image/heic or image/heif encoder, this tool lets you create HEIC files without installing extra software. If not, it clearly indicates the limitation and suggests safe fallbacks.
Follow these steps to see whether your environment supports AVIF → HEIC conversion:
Upload one or more AVIF images by dragging and dropping or clicking the upload button.
Optionally enable resizing and configure maximum width and height for your images.
Start the conversion and, if successful, download your generated HEIC files.
Because HEIC encoding is experimental in browsers, this tool focuses on transparency and safety.
AVIF and HEIC are both modern formats; in some ecosystems HEIC remains the default.
Because HEIC encoding via browser APIs is not guaranteed, keep these points in mind:
This AVIF to HEIC converter helps you explore what your browser and OS can do with HEIC encoding, while keeping all processing on your device.
Use it as both an experimental converter and a capability tester, and rely on offline tools whenever browser support is not sufficient.

No. Very few browsers expose a HEIC/HEIF encoder to web pages. This tool checks for support and only succeeds when your environment provides a compatible encoder.
