UYVY to G3 conversion is the process of transforming image frames encoded in the UYVY (YUV 4:2:2 packed) pixel format into the G3 (Group 3 fax) raster image format used for monochrome, run-length–encoded fax images. This conversion remaps color/chroma-subsampled luma data into a bilevel or halftone representation and applies Group 3 compression suitable for fax transmission or archival.

UYVY files typically use the video/uyvy MIME type and are common in video capture and processing environments. G3 files are associated with image/g3fax MIME type and are widely used for fax and scanned document storage due to efficient compression. Codecs for UYVY focus on uncompressed or lightly compressed video streams, whereas G3 employs Group 3 fax compression algorithms.
The G3 (.G3) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like UYVY.
While specific technical details aren't available here, G3 files generally serve the purpose of storing image effectively within their domain.
Our online UYVY to G3 converter offers a seamless way to transform your UYVY files into the efficient G3 format. Designed for users who need quick and reliable conversions without compromising quality, this tool supports fast uploads and downloads with no software installation required.
UYVY is a raw video data format known for preserving color fidelity but often results in larger file sizes. G3, on the other hand, is a compressed image format that significantly reduces file size while maintaining acceptable visual quality. Choosing G3 over UYVY is ideal for applications needing smaller, more manageable files.
Keep individual UYVY frames reasonably sized: for G3 fax output target ~1728 pixels/line; larger widths increase processing time and output size.
Preserve quality by applying proper luminance-to-bilevel conversion: use adaptive dithering for photographic content and simple thresholding for text/line art.
For batch jobs, convert in groups using consistent binarization settings and process at a fixed resolution to maintain uniform G3 compression efficiency.
Expect loss of color and chroma detail: G3 is monochrome and relies on effective binarization—color-to-grayscale conversion should use weighted Y channel from UYVY.
