How to Convert EXR to AVIF

EXR's floating-point precision is built for production work, not web delivery, while AVIF supports up to 12-bit color and highly efficient AV1-based compression, making it one of the few common consumer formats with any meaningful HDR-adjacent capability. Converting an EXR render to AVIF can preserve more of the tone-mapped highlight and shadow detail than converting to a standard 8-bit format, while still producing a file small enough to publish online.

This is still a significant reduction from EXR's full floating-point range, since AVIF's 12-bit integer values can't match the unbounded precision of true floating-point data, but it's a reasonable middle ground when sharing render previews or portfolio work that benefits from slightly more tonal range than JPG or PNG provide.

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 EXR.
3. Drag your EXR file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to EXR and the "To" format to AVIF.
5. Adjust the quality setting to balance file size against visual detail.
6. Click Convert. AVIF files are written to your output folder, fully offline.

• 100% offline — your renders and plates are never uploaded anywhere
• Better preserves tonal detail than converting to standard 8-bit formats
• Bulk conversion of entire render output folders, including sub-folders, in one pass
• Multi-core processing helps offset AVIF's heavier encoding cost
• Option to delete original EXR files automatically once converted
• No recurring subscription or hidden upload limits
