About formats

ORF (Olympus RAW Format) is the proprietary RAW image format used by Olympus (now OM Digital Solutions) digital cameras, introduced in 2000 with the E-10 digital SLR and continuing through the entire Micro Four Thirds OM-D and PEN lineups. ORF files capture the unprocessed 12-bit or 14-bit readout from the camera's Four Thirds or Micro Four Thirds Live MOS or CCD sensor, preserving the complete Bayer-pattern mosaic data before any demosaicing, noise reduction, or color processing. The format uses an Olympus-specific container that stores the raw data with lossless compression alongside multiple embedded JPEG previews, extensive EXIF metadata, and Olympus MakerNote tags encoding Art Filter settings, in-body image stabilization parameters, face/eye detection results, and computational photography mode information. ORF has evolved across several generations of Olympus sensors, from the original 4-megapixel Four Thirds CCD to the 20+ megapixel stacked sensors in current OM System bodies, and the format has accommodated these changes while maintaining backward compatibility in processing software. One advantage is the Micro Four Thirds system's depth-of-field characteristics: ORF files from these smaller sensors deliver greater depth of field at equivalent apertures compared to full-frame, a genuine advantage for macro, landscape, and travel photography where sharpness throughout the frame matters. Wide processing support is another strength — ORF files are handled by Adobe Lightroom, Capture One, DxO, Olympus/OM Workspace, dcraw, and RawTherapee.
Developer: Olympus
Initial release: 2000
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 ORF to PGX?

PGX is a reference format for JPEG 2000 conformance testing. Converting from ORF creates images suitable for standards validation and testing tools.

What programs open PGX?

PGX is supported by JPEG 2000 reference software, ImageMagick, and standards-testing tools.

Is ORF to PGX conversion free on Convertio?

Standard ORF to PGX conversions are free on convertio.tools. Larger volumes or bigger images may benefit from a premium account for faster processing.

Does the conversion preserve image quality?

The converter processes your Olympus ORF sensor data carefully to produce the best possible PGX output. Quality depends on the target format's capabilities.

Can I convert multiple ORF photos at once?

Yes — batch upload is supported. Queue several Olympus ORF images and convert them all to PGX in one session without repeating the process.

Does this work with all Olympus cameras?

The converter supports ORF from all Olympus camera models — whether you shoot with an entry-level body or a professional flagship.
