About formats

PAM (Portable Arbitrary Map) is a raster image format added to the Netpbm family around the year 2000 by Bryan Henderson, the maintainer of Netpbm, as a generalization that unifies and extends the original PBM, PGM, and PPM formats. Where the classic Netpbm formats each handle a specific image type (PBM for bilevel, PGM for grayscale, PPM for color), PAM provides a single format that can represent any combination of channels, bit depths, and image types through a flexible ASCII header. The PAM header uses keyword-value pairs: WIDTH, HEIGHT, DEPTH (number of channels), MAXVAL (maximum sample value, up to 65535), and TUPLTYPE (a string identifying the image type — BLACKANDWHITE, GRAYSCALE, RGB, GRAYSCALE_ALPHA, RGB_ALPHA, or custom types). After the header, pixel data is stored in binary, with each sample occupying one or two bytes depending on MAXVAL. PAM's key innovation over its predecessors is native alpha channel support: GRAYSCALE_ALPHA (2-channel) and RGB_ALPHA (4-channel) tupletypes provide transparency without requiring a separate mask file, something the original PBM/PGM/PPM formats could not express. One advantage is format unification: a single PAM-reading implementation handles monochrome, grayscale, color, and alpha-augmented images, eliminating the need for separate parsers for each Netpbm variant. The extensible TUPLTYPE mechanism provides another practical strength — custom channel configurations (multispectral, depth + color, or any application-specific arrangement) can be represented and labeled without modifying the format specification. PAM is supported by Netpbm tools, ImageMagick, GIMP, and programming libraries that process the Netpbm family.

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.

Frequently Asked Questions

Why convert PAM to UYVY?

Switch to UYVY for 16-bit interleaved YUV — it works with more applications and platforms than PAM typically does.

What programs open UYVY files?

For UYVY files, try ImageMagick, raw video/image processors. Cross-platform support means you can view them on any operating system.

Will I lose image quality converting PAM to UYVY?

Quality stays intact during conversion. The output UYVY file faithfully represents what was stored in the original PAM image.

Can I convert multiple PAM files to UYVY at once?

Absolutely — queue up multiple PAM files and the converter handles each one, producing UYVY outputs for all of them.

Is the PAM to UYVY conversion instant?

Processing is fast — most PAM files convert to UYVY within a few seconds, depending on image dimensions and server load.

Do I need to create an account to convert?

No sign-up necessary. The converter works without an account for regular PAM to UYVY conversions.
