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
PSD (Photoshop Document) is the native file format of Adobe Photoshop, the industry-standard raster image editor first released on February 19, 1990. PSD files preserve the complete editing state of a Photoshop project: all layers (raster, text, adjustment, shape, and smart object layers) with their positions, blending modes, opacity, and layer effects; layer masks and vector masks; alpha channels; spot color channels; paths; guides; slices; and the full undo history. The format supports images up to 30,000 x 30,000 pixels (PSB, the large document format, extends this to 300,000 x 300,000) in color modes including RGB, CMYK, Lab, Grayscale, Indexed, Duotone, and Multichannel, at 1, 8, 16, or 32 bits per channel. PSD files use a combination of RLE compression for individual layer data and store composite (flattened) preview images for quick display by applications that cannot parse the full layer structure. The format has become a de facto standard for professional creative workflows far beyond Photoshop itself — photographers, graphic designers, web developers, and video post-production artists exchange PSD files as the working format that preserves creative flexibility. One advantage is the non-destructive editing model: PSD preserves every layer, mask, adjustment, and effect as independently editable elements, allowing creative decisions to be revised at any point without starting over. The format's role as the interchange standard for the creative industry provides another core strength — PSD files can be opened by Adobe Illustrator, InDesign, After Effects, Premiere Pro, as well as Affinity Photo, GIMP, Sketch, Figma, and Photopea, making it the lingua franca of visual design.

Frequently Asked Questions

Why convert PGX to PSD?

PGX files have limited software support. Converting to PSD ensures your images are accessible on all modern devices and platforms.

What programs open PSD files?

PSD files open in most image viewers and editors — including web browsers, system preview tools, Photoshop, GIMP, and Paint on Windows.

Why is PGX not widely supported?

PGX was created specifically for JPEG 2000 testing — a narrow technical purpose. It was never designed for everyday image storage or distribution.

How many files can I convert at a time?

You can upload and convert multiple PGX files to PSD in a single session. Each conversion processes in parallel for faster results.

Is my PGX data kept private?

Uploaded files are deleted immediately after conversion, and converted files are removed within 24 hours. Your data stays private and secure.
