Why does this produce a JPEG instead of HEIC?

No browser supports native HEIC encoding due to patent and licensing restrictions on the HEVC codec used by HEIC/HEIF. JPEG at 95% quality is the practical browser-safe alternative and is visually indistinguishable from HEIC for most content.

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?

Chrome 85+, Firefox 93+, and Safari 16.4+ all support AVIF decoding natively. If your browser is older you will see an error and should upgrade before using this tool.

Will transparency in my AVIF be preserved?

JPEG does not support transparency. Any transparent areas in your AVIF file will be filled with a white background in the JPEG output, which mirrors how HEIC handles conversion in most workflows.

How do I get a true HEIC file from AVIF?

True AVIF-to-HEIC conversion requires a native OS tool or application. On macOS, use the built-in "sips" command: sips -s format heic input.avif --out output.heic. On Windows, use a tool such as ImageMagick with the HEVC codec pack installed.

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.

Summary

Upload an AVIF file and download it as a high-quality JPEG — the browser-safe equivalent of HEIC — with no uploads or signup required.

How it works

Click the upload area or drag and drop an AVIF file onto it.
Your browser decodes the AVIF image natively (Chrome 85+, Firefox 93+, Safari 16.4+).
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 file — HEIC-equivalent quality, no server required.

Use cases

Convert AVIF photos to a format compatible with older iOS and macOS apps.
Prepare AVIF images for software or services that only accept HEIC or JPEG.
Share AVIF files with iPhone users whose apps expect HEIC-format images.
Reduce AVIF file sizes further by tuning the output quality slider.
Preview AVIF images in a browser and export them for archiving.
Quickly convert AVIF screenshots for use in presentations or documents.
