CFF to T11 conversion is the process of transforming files saved in the CFF (Custom File Format) container into the T11 (T11) format so they can be opened, edited, or processed by applications that require T11. This conversion remaps CFF's internal structures—such as embedded metadata, resource blocks, and compression streams—into T11's schema while attempting to preserve content integrity and metadata where format compatibility allows.

Quality preservation: choose lossless or high-quality T11 settings when preserving original fidelity matters; avoid aggressive compression if you need exact metadata or resource integrity.
Batch conversion: convert multiple CFF files in a single job to save time, but group by similar settings (same quality/compression) to avoid per-file reconfiguration.
Format-specific limitation: some advanced CFF-specific resource types or custom plugins may not map perfectly to T11 and could be exported as auxiliary files or omitted with a warning.
