About formats

EMF (Enhanced Metafile) is a vector graphics format developed by Microsoft as the successor to WMF (Windows Metafile), introduced with Windows NT 3.1 in July 1993. EMF records a sequence of GDI (Graphics Device Interface) function calls that describe vector shapes, text, embedded bitmaps, and rendering attributes in a device-independent manner. Unlike WMF's 16-bit coordinate system limited to 65,536 units, EMF uses 32-bit coordinates and adds support for Bezier curves, advanced path operations, world coordinate transforms, gradient fills, and extended text capabilities including Unicode. The format functions as a graphics recording mechanism — applications capture their drawing operations into an EMF file, which can then be replayed at any scale on any device with full geometric precision. One advantage is native Windows integration: EMF is the standard clipboard and spooler format for vector content across the Windows ecosystem, enabling lossless copy-paste of graphics between Office documents, design tools, and presentation software without rasterization. Resolution independence is another key strength — EMF graphics scale smoothly from screen display to high-resolution print output. An extended variant, EMF+, introduced with GDI+ adds anti-aliasing, alpha transparency, and advanced brush types. EMF remains deeply embedded in Windows-based publishing, technical documentation, and enterprise document workflows.
Developer: Microsoft
Initial release: July 27, 1993
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.

Frequently Asked Questions

Why convert EMF to PGX?

EMF is a Windows-only vector format with limited cross-platform support. Converting to PGX makes your graphic viewable on any device and operating system.

What programs open PGX files?

You can open PGX files with JPEG 2000 reference software, OpenJPEG tools, or specialized viewers.

Can I batch-convert multiple EMF files to PGX?

Yes — upload several EMF files at once and Convertio processes them to PGX in parallel, saving you time.

Is a Convertio account needed for EMF to PGX?

No — you can convert EMF to PGX without creating an account or providing any personal information.

What platforms support this EMF to PGX converter?

Any platform with a browser — Windows, macOS, Linux, Android, iOS, and Chrome OS all work perfectly.

Is EMF to PGX conversion fast?

Very fast — Convertio processes files on cloud servers, so even older or mobile devices get quick results.
