How to Convert TIFF to AVIF

TIFF files, especially uncompressed scans or camera exports, can be enormous compared to what's actually needed for viewing or sharing, while AVIF's AV1-based compression delivers some of the smallest file sizes available for a given visual quality. Converting a batch of TIFF files to AVIF can shrink storage and bandwidth requirements dramatically, which matters most for large scanned document archives or photo libraries originally kept in TIFF for archival purposes.

The tradeoff is that AVIF's lossy modes won't preserve TIFF's lossless quality the way PNG would, and AVIF encoding takes more processing time than simpler formats, though its lossless mode remains an option if retaining exact quality matters more than maximum compression.

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 TIFF file.
3. Drag your TIFF file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to TIFF 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 scans and photos are never uploaded anywhere
• Bulk conversion of entire archives, including sub-folders, in one pass
• Dramatic file size reduction compared to uncompressed or lightly compressed TIFF
• Multi-core processing helps offset AVIF's heavier encoding cost
• Option to delete original TIFF files automatically once converted
• No recurring subscription or hidden upload limits
