VIPS to G4 conversion is the process of transforming an image stored in the VIPS (a high-performance image processing format often used with the libvips library) into a G4 (Group 4) fax-compressed TIFF stream, producing a bi-level (black-and-white) image optimized for faxing and archival. This conversion typically involves dithering or thresholding and applying CCITT Group 4 compression to reduce size while preserving legibility for documents and line art.

VIPS files typically use the image/vips MIME type and support a variety of image codecs depending on source content. G4 files use the image/g3fax MIME type and are mainly applied in fax transmission and scanned document archiving. The G4 format utilizes CCITT Group 4 compression designed for bi-level black and white images.
The G4 (.G4) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like VIPS.
While specific technical details aren't available here, G4 files generally serve the purpose of storing image effectively within their domain.
Easily convert your VIPS files to the G4 format online using our user-friendly VIPS to G4 converter. Designed for efficiency and quality, this tool lets you transform your images without the need for software installation or technical expertise.
VIPS is a versatile image processing format suited for high-performance workflows, while G4 is specialized for bi-level images optimized for fax and document scanning. VIPS supports color and multi-channel images, whereas G4 focuses on compression efficiency for monochrome data. Choosing G4 for VIPS conversion ensures smaller file sizes ideal for document transmission.
Keep source pages already close to black-and-white (scanned text) for best results: photos and continuous-tone images will require aggressive dithering that reduces clarity.
Optimal file sizes: for single-page text scans, expect G4 files in the tens to a few hundreds of KB; multi-page documents scale linearly—try to keep each page under ~1–2 MB before conversion for speed.
Preserve quality by pre-processing in VIPS: apply contrast/deskew and remove background gradients before converting to bi-level to reduce artifacts.
For batch conversion, process files with identical settings (threshold or dither) to ensure uniform output; use a CLI tool or script with libvips for fast, memory-efficient bulk operations.

Format limitation: G4 is bi-level only (1 bit per pixel) and cannot represent grayscale or full color, so expect loss of gray/photo detail when converting.
