About formats

SRF (Sony RAW Format) is the earliest proprietary RAW image format used by Sony digital cameras, introduced in 2003 with the Cyber-shot DSC-F828 and also used by the DSC-V3 compact camera. SRF files capture the unprocessed sensor readout at 12 bits per channel, preserving the raw Bayer-pattern data from the camera's CCD sensor before any demosaicing, white balance, or compression processing. The DSC-F828 was notable for its unique 4-color RGBE (Red, Green, Blue, Emerald) CCD sensor design — an attempt to capture a wider color gamut by adding a cyan-shifted fourth color filter element — and SRF files from this camera store the raw 4-color mosaic data needed to take advantage of this unconventional sensor layout. The format uses a proprietary container structure with Sony-specific metadata tags recording exposure parameters, lens position, and camera settings. SRF was succeeded by SR2 and then ARW as Sony expanded into interchangeable-lens cameras with the Alpha DSLR system from 2006 onward. One advantage is the capture of data from genuinely innovative sensor technology — the DSC-F828's 4-color filter array was a unique experiment in consumer camera design, and SRF files preserve the raw 4-channel data that enables exploration of the extended color gamut this sensor design was intended to provide, particularly in the cyan-green portion of the spectrum where standard Bayer sensors have gaps. Despite the format's obscurity, SRF files remain processable: Adobe Camera Raw, dcraw, LibRaw, and RawTherapee all support SRF, ensuring these early Sony RAW files remain accessible for modern processing.
Developer: Sony
Initial release: 2003
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 SRF to PGX?

Almost no modern image application recognizes SRF — converting to PGX lets you finally edit, share, and print these early Sony RAW photos.

What opens PGX files?

PGX files can be opened with ImageMagick, JPEG 2000 reference software, and conformance testing tools.

Is batch conversion available for SRF to PGX?

Yes. You can upload many SRF files together and convert them all to PGX in a single session.

Does SRF to PGX work on Mac and Linux?

Convertio runs entirely in the browser — it works on Windows, macOS, Linux, and even mobile devices with no installs.

How long does SRF to PGX conversion take?

Most conversions finish in just a few seconds — server-side processing handles the heavy lifting, not your device.
