TCR to G3 conversion is the process of transforming an ebook or text resource stored in the TCR (Text Compression/Container) format into the G3 (G3 Ebook) format used by certain e-readers and ebook platforms. This conversion repackages and, when necessary, transcodes internal text, metadata, and images so the content displays correctly in G3-compatible readers.

Batch convert files in groups of 10–20 to avoid timeouts or memory limits on web-based converters; for large batches use a desktop tool or API.
Note format limitation: some TCR-specific styling or proprietary markup may not map perfectly to G3 and may require manual adjustment after conversion.
