How to Convert PBM to AVIF

PBM's 1-bit-per-pixel structure was designed for the most basic monochrome document transmission, with no color or grayscale capability whatsoever. AVIF, by contrast, supports up to 12-bit color and highly efficient AV1-based compression, but converting a PBM file to AVIF doesn't unlock any of that capability for the actual image content — the original black-and-white data simply moves into a more modern, broadly supported container.

This conversion is mainly useful when a legacy document scan or bilevel pipeline output needs to be archived or published using AVIF specifically for its compatibility with current web platforms, even though the underlying image remains as basic as it was in PBM.

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 PBM.
3. Drag your PBM file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to PBM and the "To" format to AVIF.
5. Click Convert. AVIF files are written to your output folder, fully offline.

• 100% offline — your document and pipeline output is never uploaded anywhere
• Bulk conversion of entire folders, including sub-folders, in one pass
• Produces AVIF files with broad current browser and platform support
• Multi-core processing for fast handling of large batches
• Option to delete original PBM files automatically once converted
• No recurring subscription or hidden upload limits
