CGM to RB conversion is the process of transforming a Computer Graphics Metafile (CGM), a device-independent vector and raster graphics format commonly used for technical drawings and diagrams, into an RB file, a raster-based drawing format used by certain legacy CAD/viewer applications. This conversion rasterizes or re-encodes CGM content into the RB pixel-based structure while attempting to preserve line art, color fills, and annotations for compatibility with RB-supporting tools.

CGM files typically use the MIME type 'image/cgm' and are used for 2D vector graphics, especially in engineering and technical drawings. RB files have the MIME type 'application/x-rb' and are used for optimized rendering in specific drawing applications. Both formats support various codecs to maintain graphic fidelity during conversion.
The RB (.RB) format is commonly used for drawing. Understanding its characteristics can be helpful when converting to or from other formats like CGM.
While specific technical details aren't available here, RB files generally serve the purpose of storing drawing effectively within their domain.
Convert your CGM drawing files to RB format quickly and easily using our online CGM to RB converter. Designed for seamless and accurate conversion, our tool supports fast processing without any software installation.
CGM files are widely used for vector graphics and technical drawings, offering high detail and scalability. In contrast, RB files are preferred in certain applications for their streamlined structure and faster rendering. While CGM emphasizes broad compatibility, RB focuses on performance and ease of use in specialized environments.
Keep input CGM files under 250 MB for fastest, most reliable online conversion; very large files may time out or require desktop tools.
To preserve fine linework, choose a higher DPI (300–600) and 24-bit color depth; avoid heavy downscaling which can blur vector edges after rasterization.
For batch conversions, compress multiple CGM files into a single ZIP and use a conversion tool that supports queueing or command-line automation to maintain consistent settings.
Be aware that CGM vector primitives are rasterized into RB; scale-dependent features (infinite canvas or interactive layers) cannot be preserved as editable vectors.
