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.

PFM (Portable Float Map) is a floating-point raster image format devised by Paul Debevec around 2001, designed to store high-dynamic-range image data with the simplicity of the Netpbm family of formats. PFM extends the PBM/PGM/PPM philosophy — minimal header, raw data, no compression — to 32-bit IEEE floating-point samples, providing direct access to HDR pixel values without the encoding overhead of formats like OpenEXR or the limited range of Radiance HDR's RGBE encoding. The file structure is deliberately minimal: a two-character magic number ('Pf' for grayscale, 'PF' for color), width and height on the next line, a scale/endianness indicator (negative for little-endian, positive for big-endian, with magnitude indicating scale factor), and then the raw 32-bit float data for each pixel. PFM files store one float per pixel for grayscale or three floats (RGB) per pixel for color, with no compression, alpha channel, or metadata support. The format emerged from the HDR imaging research community where Debevec's work on image-based lighting and light stage capture required a simple, unambiguous way to store linear floating-point radiance values that could be easily exchanged between research tools. One advantage is absolute simplicity for HDR data: PFM can be read and written in a few lines of code in any language that supports IEEE floats, with no library dependencies — ideal for research prototyping and quick data exchange between custom tools. The format's widespread adoption in the computer vision and computational photography research community is another practical strength — optical flow benchmarks (Middlebury), depth estimation datasets, and radiance field captures commonly use PFM. The format is supported by ImageMagick, OpenCV, HDR Shop, and Luminance HDR.

Frequently Asked Questions

Why convert UYVY to PFM?

The UYVY format has limited viewer support. Converting to PFM ensures broad compatibility across devices.

How do I open PFM files?

Use HDR imaging tools, GIMP to view PFM files. This format enjoys broad software support on all major platforms.

Can I convert multiple UYVY files at once?

Batch conversion is supported — upload several UYVY files and each will be independently converted to PFM format.

What happens to my file after conversion?

Your uploaded UYVY file and the resulting PFM output are automatically deleted from the server within 24 hours to protect your data.

What platforms support this conversion?

The converter runs entirely in the browser, so it works on Windows, macOS, Linux, iOS, and Android without issues.

How long does UYVY to PFM conversion take?

Seconds for most files. Convertio processes UYVY data on powerful servers, so even bigger files convert quickly.
