About formats

PGX is a simple single-component raster image format defined as part of the JPEG 2000 standard (ISO/IEC 15444) for use in conformance testing and verification of JPEG 2000 codec implementations. Introduced around 2000 alongside the JPEG 2000 specification itself, PGX files store a single image component (one color channel or grayscale plane) with a text header followed by raw pixel data, providing an unambiguous reference representation against which encoder and decoder outputs can be compared sample by sample. The header is a single ASCII line specifying endianness (ML for big-endian, LM for little-endian), signedness (+ for unsigned, - for signed), bit depth (1 to 32 bits), width, and height. The pixel data follows as raw binary values, each occupying the minimum number of bytes needed for the specified bit depth, with one value per pixel. For multi-component images (like RGB), each component is stored in a separate PGX file. The format's deliberate simplicity — no compression, no metadata, no multi-channel support — ensures there are no ambiguities in interpretation that could mask codec bugs. One advantage is verification precision: PGX's uncompressed, exactly-specified representation allows bit-exact comparison of decoded JPEG 2000 output against reference images, essential for certifying that a codec implementation conforms to the standard. The format's role in the JPEG 2000 conformance testing framework means it is implemented by every serious JPEG 2000 codec (OpenJPEG, Kakadu, etc.) and used in the official ISO conformance test suite. PGX files can also be processed by ImageMagick and various JPEG 2000 development tools.
Initial release: 2000
XPS (XML Paper Specification) is a fixed-layout document format developed by Microsoft, first released with Windows Vista and .NET Framework 3.0 in November 2006. Conceived as Microsoft's alternative to Adobe's PDF, XPS uses XML-based page description markup within a ZIP-based Open Packaging Conventions container. Each page is described as a FixedPage element containing paths (vector shapes with fill and stroke), glyphs (text positioned at precise coordinates), images, and canvas groupings — all specified with exact coordinates for pixel-precise rendering. The format embeds all required resources: fonts are subset and included, images are stored within the package, and the complete rendering specification travels with the document. Windows includes the XPS Document Writer as a virtual printer, allowing any application to generate XPS output through the standard print dialog. One advantage is exact visual fidelity — XPS documents render identically on any compliant viewer because every element is positioned absolutely, with no interpretation variance. Native Windows integration is another strength: XPS viewing, creation, and printing are built into Windows without additional software, and the .NET Framework provides APIs for programmatic XPS generation. While XPS did not achieve the ubiquity of PDF as a universal document format, it remains used in Windows printing infrastructure, enterprise document workflows, and scenarios where the Windows platform provides native end-to-end support.

Frequently Asked Questions

Why convert PGX to XPS?

Converting PGX to XPS creates a portable document you can share via email or print — no special image viewers needed on the other end.

What programs open XPS files?

XPS files work in their native application ecosystem. Most operating systems include built-in support or free readers for this format.

Where do PGX files come from?

PGX files originate from JPEG 2000 conformance test suites. They serve as reference images for validating standard-compliant decoders and encoders.

What happens to uploaded files?

Your PGX files are processed on secure servers, then deleted automatically. Converted XPS files are available for 24 hours, then erased.

Does converting PGX to XPS lose quality?

Conversion preserves the quality present in the PGX original. Any limitations come from the source resolution, not from the conversion step.
