G4 to VIFF conversion is the process of transforming an image encoded with the G4 (Group 4) fax/compression format into the VIFF (Khoros Visualization Image File Format) raster image format. This conversion repackages the monochrome, run-length compressed data used in G4 into the structured multi-image/metadata container used by VIFF for visualization and analysis.

G4 files typically use the image/g3fax MIME type and are compressed using CCITT Group 4 codecs, common in fax transmissions. VIFF files use the image/vnd.viff MIME type and support various codecs for storing multi-dimensional images including scientific data. VIFF is widely used in specialized imaging and research fields.
The VIFF (.VIFF) 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, VIFF files generally serve the purpose of storing image effectively within their domain.
Our Online G4 to VIFF Converter offers a fast, secure, and user-friendly way to convert your G4 files into VIFF format without downloading any software. Designed specifically for image conversion needs, this tool ensures high-quality results compatible with various applications.
G4 is a fax image format primarily used for single-bit images, while VIFF is a versatile image format designed for complex and multi-dimensional image data. VIFF supports a broader range of color depths and metadata, making it suitable for advanced image processing compared to the simpler G4 format.
Keep source files under 5–10 MB per page when possible to speed up conversion and reduce memory use; very large multipage G4 TIFFs can be split before converting.
To preserve exact black-and-white fax fidelity, export VIFF as 1-bit bilevel; if you need display-friendly images, convert to 8-bit grayscale during conversion.
For batch conversion, process files as a queue and convert pages to separate VIFF frames or use scripting tools that support TIFF/G4 and VIFF to avoid manual work.
Note limitation: G4 is strictly bilevel (monochrome) and cannot store color — color information will not be created during conversion, only approximated by dithering if you expand to grayscale.
