G4 to UYVY conversion is the process of transforming images encoded with Group 4 (G4) Fax compression, a bi-level CCITT standard primarily used for scanned black-and-white documents, into UYVY, a packed YUV 4:2:2 pixel format used for color video and image processing. This conversion involves decoding the G4 compressed monochrome raster, optionally expanding or dithering to color or grayscale channels, and re-encoding pixels into the UYVY planar-interleaved chroma format for video workflows or processing pipelines.

The G4 format typically uses the 'image/g4' MIME type and is used for bi-level fax images employing CCITT Group 4 compression. UYVY files usually fall under 'video/x-uyvy' MIME type and are common in raw video streams utilizing YUV 4:2:2 color encoding. Codecs that support UYVY include various video capture and editing software codecs optimized for color video.
The UYVY (.UYVY) 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, UYVY files generally serve the purpose of storing image effectively within their domain.
Easily convert your G4 files to UYVY format using our online converter designed for quick, secure, and lossless transformations. Whether you need to update your image or video formats, our tool supports seamless conversion from G4 to UYVY without any software installation.
G4 is primarily a monochrome image format focused on fax and document scanning, while UYVY is a color video format widely used in video capture and processing. UYVY supports chroma subsampling which enhances color fidelity, unlike the G4 format. Converting from G4 to UYVY updates the media to a more versatile and widely supported format.
Keep source G4 files under 250MB for fastest browser-based conversion; split large multi-page TIFFs when possible.
To preserve detail, convert G4 bitmaps to 8-bit luminance first and apply controlled dithering rather than simple nearest-neighbor expansion.
For batch jobs, process multi-page TIFFs or use a command-line tool to convert multiple files in a single run to keep metadata and page order intact.
Understand format limitations: G4 is 1-bit bi-level only (no color or intermediate gray levels), so accurate color reconstruction in UYVY requires deliberate mapping or artificial gray expansion.
