How to Convert PPM to AVIF

PPM's uncompressed storage means even simple image content takes up far more space than necessary, while AVIF's AV1-based compression produces some of the smallest file sizes available for a given visual quality. Converting research or pipeline output from PPM to AVIF can shrink file sizes dramatically, which matters most once you're dealing with a large batch of PPM files generated by an automated process.

AVIF's more advanced compression takes longer to encode than simpler formats, but multi-core batch processing keeps this manageable even for large PPM collections.

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