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
AW is the document format of Applix Words, the word processor component of the Applix office suite (later renamed Anyware Office) developed by Applix, Inc. for Unix and Linux workstations. The suite targeted enterprise Unix environments during the 1990s, providing word processing, spreadsheet, graphics, and presentation capabilities on platforms like Solaris, HP-UX, AIX, and Linux where Microsoft Office was unavailable. AW files store formatted text documents with support for character and paragraph styling, page layout, tables, headers and footers, and embedded graphics. The format uses a proprietary binary structure optimized for the Applix application's internal document model. Applix Words gained particular visibility in the Linux community during the late 1990s when it was bundled with several commercial Linux distributions as their default word processor before OpenOffice.org became widely available. One advantage was native Unix platform support — Applix provided professional word processing capabilities on Unix workstations at a time when few commercial alternatives existed. The format's tight integration with other Applix suite components enabled cross-referencing between word processing documents, spreadsheets, and presentations. Applix was acquired by Cognos in 2003, and the office suite was discontinued. AW files are primarily encountered today in archived documents from Unix enterprise environments of the 1990s and early 2000s.

Frequently Asked Questions

Why convert PGX to AW?

AW embeds the image in a structured document layout, making PGX content easy to distribute, annotate, and print anywhere.

What programs open AW files?

View AW files using the appropriate reader application — free options exist for every major operating system and mobile platform.

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.

Which platforms are supported?

Every platform with a modern browser works — Windows, macOS, Linux, ChromeOS, iOS, and Android all run the PGX to AW converter perfectly.

Can I convert multiple PGX files at once?

Yes — upload several PGX files in a single session and convert them all to AW simultaneously. Batch processing saves considerable time.
