About formats

UYVY is a packed pixel format for storing images and video frames in YUV 4:2:2 chroma-subsampled color space, with the UYVY designation indicating the byte ordering within each 4-byte macropixel: U (Cb), Y0, V (Cr), Y1. Each macropixel encodes two horizontal pixels sharing a single pair of chrominance samples (U and V) but retaining individual luminance values (Y0 and Y1), achieving 2:1 horizontal chroma subsampling that reduces data size by 33% compared to full 4:4:4 YUV while maintaining full luminance resolution. The UYVY ordering is specified as a FOURCC code in Microsoft's Video for Windows and DirectShow frameworks, and is commonly used in professional video capture cards, broadcast equipment, and video processing pipelines. UYVY raw files contain no header — the pixel data is a flat sequence of U,Y,V,Y byte quadruplets, requiring external specification of image dimensions. The 4:2:2 subsampling exploits the human visual system's lower spatial resolution for color compared to brightness: the eye notices luminance detail at much higher spatial frequencies than chrominance detail, so sharing color samples between adjacent pixels produces no visible quality loss in practice. One advantage is broadcast-standard compatibility: UYVY's 4:2:2 sampling matches the chrominance structure used in professional video standards (ITU-R BT.601, SDI), making it the natural format for video capture hardware and frame-accurate processing. The format's efficient memory layout is another strength — the packed byte arrangement enables fast DMA transfers between capture hardware and system memory. UYVY data is handled by FFmpeg, ImageMagick, and professional video capture/editing software.

FAX is a generic image file extension associated with facsimile transmission formats standardized by the ITU-T (formerly CCITT), with the underlying Group 3 compression standard ratified in 1980. FAX files typically contain monochrome (1-bit, black and white) image data compressed using the Modified Huffman (MH) encoding defined in ITU-T Recommendation T.4, which assigns variable-length codes to run lengths of consecutive white or black pixels along each scanline. The standard resolution for Group 3 fax is 204x98 dpi (normal mode) or 204x196 dpi (fine mode), reflecting the capabilities of thermal and laser fax machines of the era. FAX files encountered digitally are often raw Group 3 encoded bitstreams or TIFF wrappers with CCITT Group 3 compression (TIFF compression tag 3). The Group 3 encoding scheme is highly efficient for typical business documents — pages with mostly white space and black text — achieving compression ratios of 10:1 to 20:1 compared to uncompressed bitmaps. One advantage is universal fax system compatibility: Group 3 encoding is the mandatory baseline for all fax machines worldwide, meaning FAX files contain data in exactly the format transmitted over telephone lines, preserving the original fax data without transcoding losses. The format's role in business communications history provides another dimension — billions of fax transmissions using this encoding moved legal documents, medical records, and business correspondence for decades, and archived FAX files represent an important documentary record. FAX images can be viewed and converted using LibreOffice, ImageMagick, GIMP, and standard document management systems.

Frequently Asked Questions

Why convert UYVY to FAX?

Transform specialized UYVY data into FAX so colleagues and clients can view it without niche software.

How do I open FAX files?

FAX files open in fax viewers, IrfanView, GIMP — widely supported across Windows, macOS, and Linux platforms.

What platforms support this conversion?

Convertio works in any modern browser — Chrome, Firefox, Safari, Edge — on Windows, macOS, Linux, and mobile.

Is UYVY to FAX conversion accurate?

The converter maintains image fidelity when transforming UYVY into FAX. Color data and dimensions are preserved accurately.

Can I convert multiple UYVY files to FAX at once?

Batch conversion is supported. Upload several UYVY files simultaneously and each one converts to FAX independently in a single session.

Is my UYVY data kept private?

Your files stay private. Source UYVY data is removed post-conversion, and FAX output is cleared within 24 hours.
