AFF to G4 conversion is the process of transforming a drawing saved in the AFF (Advanced File Format) into the G4 raster/vector graphic format used for engineering and printing workflows. This conversion maps AFF drawing elements, layers, and metadata into the G4 structure while applying appropriate compression and rendering rules to preserve linework and scale.

AFF files usually use the MIME type image/vnd.hp-fax, supporting multiple image compressions including CCITT Group 4. G4 files use the MIME type image/g4 fax, which applies CCITT Group 4 compression primarily for monochrome images. Both formats are widely used in document imaging and fax applications.
The G4 (.G4) format is commonly used for drawing. Understanding its characteristics can be helpful when converting to or from other formats like AFF.
While specific technical details aren't available here, G4 files generally serve the purpose of storing drawing effectively within their domain.

AFF files typically serve as a flexible format for scanned images, while G4 files use a more compressed fax-standard encoding. G4 is optimized for monochrome image data, making it ideal for fax transmissions, whereas AFF supports multiple image types with less compression. Choosing G4 can lead to smaller file sizes suitable for faxing and storage.
Keep individual AFF drawings under 50–100MB for optimal upload and processing speed; very large files can slow conversion or time out.
To preserve sharp linework, export AFF with native vector layers enabled and choose lossless G4/CCITT Group 4 output rather than aggressive compression.
For batch conversions, group files by similar page size and resolution to avoid reprocessing settings; use a queued or bulk-conversion tool to save time.
Limitations: G4 (CCITT Group 4) is optimized for 1-bit monochrome images—complex color fills or continuous-tone images will be dithered or flattened.

If your AFF uses advanced metadata or proprietary objects, some semantic information (custom attributes) may not map perfectly to G4; export attributes separately if needed.
