G4 to HRZ conversion is the process of transforming images stored in the G4 format (a Group 4 bi-level/CCITT Fax compression variant commonly used for scanned black-and-white documents) into the HRZ format, a raster image/container format used for high-resolution archive or proprietary imaging workflows. This conversion decodes the G4-compressed bitonal image and repackages or re-encodes it into HRZ while preserving resolution, layout, and metadata where possible.

The G4 format typically uses the TIFF image container with CCITT Group 4 compression, mainly employed in fax transmissions and scanned documents. HRZ is a proprietary or modern container format utilizing advanced codecs for improved compression and faster rendering. Both formats serve specialized roles, but HRZ is favored for enhanced efficiency and multimedia integration.
The HRZ (.HRZ) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like G4.
While specific technical details aren't available here, HRZ files generally serve the purpose of storing image effectively within their domain.

G4 is a legacy compression format primarily used for fax and scanned images, offering moderate quality and compatibility. HRZ is a newer, more efficient format designed for higher compression and faster decoding, making it ideal for digital workflows and advanced applications. Choosing HRZ over G4 ensures better performance and broader software support.
Keep source files between 50KB and 10MB for single-page scans to balance quality and performance; very high-resolution scans (multi-megapixel) can exceed this and slow conversion.
To preserve quality, convert G4 TIFFs to HRZ using lossless HRZ settings and retain original DPI and bitonal color depth (1-bit) rather than forcing grayscale or color.
For large folders, use batch conversion with queued processing and test with a sample file to confirm settings; split very large multi-page TIFFs to avoid memory spikes.
Limitations: G4 is strictly bi-level (black-and-white) so converting to HRZ won’t magically add grayscale detail; OCR and noise-reduction should be applied before conversion if needed.
