Why does this produce a JPEG instead of HEIC?

Standard browser Canvas APIs do not provide HEIC encoding. This tool therefore produces a clearly labeled 95%-quality JPEG, which is a widely compatible alternative but is not a HEIC file.

Is my AVIF image uploaded to a server?

No. The entire conversion runs inside your browser using the HTML5 Canvas API. Your image is never transmitted over the network, so your privacy is fully protected.

Which browsers can decode AVIF?

AVIF decoding depends on the browser version and installed platform codecs. The tool tests the selected file and displays an error when the current browser cannot decode it.

Will transparency in my AVIF be preserved?

No. JPEG does not support transparency, so transparent areas in the AVIF are filled with a white background.

How do I get a true HEIC file from AVIF?

Use a native image application or command-line tool that explicitly includes both an AVIF decoder and a HEIC/HEIF encoder. Confirm those codec capabilities in that tool before converting; this browser tool does not create HEIC files.

What is the maximum AVIF file size I can convert?

There is no server-side limit since everything runs locally. Very large AVIF files (above 20 MP) may be slow depending on your device memory, but most files convert in under two seconds.

AVIF to HEIC Alternative (JPEG)

Upload an AVIF file and download it as a high-quality JPEG alternative — not HEIC — with no uploads or signup required.

Note: Browsers cannot encode native HEIC due to HEVC codec restrictions. This tool instead exports a clearly labeled high-quality JPEG (95%).

Summary

AVIF is a modern compressed image format, while HEIC (High Efficiency Image Container) is commonly used for Apple device photos. Standard browser Canvas APIs do not offer HEIC output encoding. This tool therefore converts your AVIF to a clearly labeled high-quality JPEG (95% quality) in your browser; it does not create a HEIC file, and the source never leaves your device.

How it works

Click the upload area or drag and drop an AVIF file onto it.
Your browser decodes the AVIF image when its installed image codecs support AVIF.
The decoded image is drawn onto an HTML5 Canvas with a white background fill.
The canvas encodes the result as a high-quality JPEG (95% quality).
A side-by-side preview and file stats are displayed instantly.
Click "Download JPEG" to save the converted JPEG file; no HEIC file is created.

Use cases

Convert AVIF photos to a format compatible with older iOS and macOS apps.
Prepare AVIF images for software or services that accept JPEG but not AVIF.
Share AVIF files with people whose apps cannot decode AVIF images.
Export a fixed 95%-quality JPEG without uploading the source file.
Preview AVIF images in a browser and export them for archiving.
Quickly convert AVIF screenshots for use in presentations or documents.
