How to Convert AVIF to HEIC

AVIF and HEIC are technically close cousins, both built on the same HEIF container structure with comparable compression efficiency, but AVIF uses the royalty-free AV1 codec while HEIC uses the patented HEVC codec. That difference matters mainly for software compatibility — Apple's ecosystem, including Photos, iOS, and macOS, has deep native support for HEIC specifically, since Apple adopted HEIC years before AVIF was standardized.

Converting AVIF to HEIC makes sense if you need an image to integrate smoothly into an Apple-centric workflow or app that expects HEIC specifically, trading AVIF's broader open-source and browser support for HEIC's tighter integration with Apple devices and software.

1. Install Turbo Batch Image Converter Pro on your Windows PC.
2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single AVIF file.
3. Drag your AVIF file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to AVIF and the "To" format to HEIC.
5. Adjust the quality setting to balance file size against visual detail.
6. Click Convert. HEIC files are written to the output folder, fully offline.

• 100% offline — your images are never uploaded anywhere
• Bulk conversion of entire folders, including sub-folders, in one pass
• Produces HEIC files with native support across Apple devices and software
• Multi-core processing for fast handling of large batches
• Option to delete original AVIF files automatically once converted
• No recurring subscription or hidden upload limits
