About formats

SR2 is an early proprietary RAW image format used by Sony for select digital camera models, most notably the Cyber-shot DSC-R1 released in 2005 — a unique fixed-lens camera featuring a large APS-C CMOS sensor that was Sony's first to use this sensor size in a compact body. SR2 files capture the unprocessed 12-bit readout from the camera's sensor in its native Bayer mosaic pattern, preserving the full dynamic range and color information before any demosaicing, white balance adjustment, or tonal processing. The format uses a TIFF-based container structure with Sony-specific metadata tags and lossless compression to keep file sizes manageable while maintaining bit-perfect sensor data preservation. SR2 represents a transitional format in Sony's imaging history: it succeeded the earlier SRF format and preceded the ARW format that would become Sony's standard RAW format across the Alpha mirrorless and DSLR lineup from 2006 onward. The DSC-R1's APS-C sensor paired with a fixed Carl Zeiss Vario-Sonnar zoom lens made it an unusual proposition — essentially a compact camera with DSLR-class image quality — and SR2 files from this camera are valued by collectors. One advantage is the preservation of data from a unique camera design: the DSC-R1's combination of large sensor and fixed optics produced a distinct imaging character, and SR2 files retain the full RAW flexibility to explore this character with modern processing tools. SR2 files are supported by Adobe Lightroom, Adobe Camera Raw, dcraw, LibRaw, and RawTherapee.

RAS (Sun Raster) is a raster image format developed by Sun Microsystems for their SunOS and Solaris Unix workstations, dating to approximately 1982. Sun Raster files store 2D bitmap images with support for 1-bit monochrome, 8-bit indexed color (with a color map), 24-bit true color (BGR byte order), and 32-bit XBGR (with an unused alpha byte). The format uses a 32-byte header containing a magic number (0x59a66a95), width, height, bit depth, data length, raster type (indicating compression), color map type, and color map length, followed by the optional color map data and the pixel data. RAS supports three encoding modes: standard (uncompressed, with each scanline padded to a 16-bit boundary), byte-encoded (run-length encoded using a simple escape-code scheme), and RGB (uncompressed with RGB rather than BGR byte order). Sun Raster was the native image format for Sun's window system and later the OpenWindows desktop environment, serving as the standard format for screenshots, icons, backgrounds, and application graphics on Sun workstations throughout the 1980s and 1990s. One advantage is the format's representation of Unix workstation computing heritage: Sun Raster files from the SunOS/Solaris era document the visual culture of an important computing platform that drove advances in networking, multiprocessing, and graphics workstation design. The format's straightforward structure is another practical strength — the 32-byte header and simple encoding make RAS files easy to parse and convert, even with custom code. RAS files are supported by ImageMagick, GIMP, XnView, and other image processing tools.

Frequently Asked Questions

Why convert SR2 to RAS?

Older Sony Alpha RAW files in SR2 format are not recognized by many modern applications — converting to RAS resolves this.

What opens RAS files?

RAS files can be opened with GIMP, XnView, IrfanView, ImageMagick, and Sun/Oracle Solaris tools.

How long does SR2 to RAS conversion take?

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

Are my SR2 files safe during conversion?

Uploaded SR2 files are deleted immediately after conversion. RAS outputs are automatically removed within 24 hours.
