TIFF to G4 conversion is the process of transforming a TIFF (Tagged Image File Format) image into a Group 4 (G4) TIFF subtype—a bilevel (black-and-white) compression format commonly used for scanned documents and fax images. The conversion typically rasterizes or thresholds grayscale/color TIFFs into 1-bit per pixel images using CCITT Group 4 compression to reduce file size while optimizing for text and line-art readability.

TIFF files typically use the MIME type image/tiff and support various compression codecs including LZW and JPEG. G4 files, often identified with MIME type image/g3fax or image/g4fax, use Group 4 fax compression designed for bi-level images. These formats are commonly used in document scanning, faxing, and archival storage where image clarity and compression efficiency are essential.
The G4 (.G4) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like TIFF.
While specific technical details aren't available here, G4 files generally serve the purpose of storing image effectively within their domain.

TIFF is a versatile and widely supported image format often used for high-quality images and scanned documents. G4 is a specialized compression format optimized for monochrome images and fax transmissions, offering superior compression ratios for black-and-white data. While TIFF supports multiple color depths and layers, G4 focuses on efficient, lossless compression primarily for black-and-white images.
Keep source files reasonably sized: optimal scanned pages are 200–300 dpi for text; higher resolutions increase file size but rarely improve OCR accuracy.
Preserve quality by choosing adaptive thresholding or Floyd–Steinberg dithering for images with grayscale; use simple threshold for clean black-and-white scans.
For large batches, convert multi-page TIFFs to multi-page G4 TIFFs to preserve document order and reduce overhead; use command-line or batch tools to automate the process.
Format limitation: G4 is strictly bilevel (1-bit) and not suitable for color photographs—color or detailed grayscale will lose information when converted.

If your TIFF is already highly compressed (e.g., JPEG-in-TIFF), convert to intermediate high-quality uncompressed TIFF only if pre-processing (deskew/clean) is required before G4 compression.
