RICH Text Format to RB conversion is the process of transforming documents saved in RTF (Rich Text Format), a widely supported text file format that preserves formatting, fonts, and basic images, into RB, a binary/document package format used for [RB-specific applications]. This conversion maps RTF styling, embedded objects, and plain text into the RB container so the document can be opened and edited by RB-compatible software or workflows.

RICH Text Format (RTF) is widely supported and designed for cross-platform document exchange with rich text formatting. In contrast, RB files are tailored for specific applications requiring more streamlined or specialized functionality. While RTF focuses on broad compatibility, RB format emphasizes optimized performance in targeted environments.
Keep individual RTF files under 50 MB for fastest uploads; large images can push size higher—optimize images before conversion.
To preserve formatting and embedded images, choose the RB "high quality" or lossless compression setting; avoid aggressive image recompression.
For large workloads, use batch conversion to combine multiple RTFs into a single RB package or convert them in parallel; monitor memory usage on local tools.
Be aware that very complex RTF features (advanced OLE objects, macros, or obscure vendor-specific controls) may not map perfectly into RB and may require manual review.
