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.
Developer: Sony
Initial release: 2005
MNG (Multiple-image Network Graphics) is an animation and multiple-image format designed as the animated counterpart to PNG, with its specification reaching version 1.0 on January 31, 2001. Developed by Glenn Randers-Pehrson and members of the PNG development community, MNG extends PNG's capabilities with support for frame-based animation sequences, slide shows, complex sprite overlays, and JNG (JPEG Network Graphics) frames for lossy compression of photographic content within the same container. An MNG file consists of a series of chunks (following PNG's chunk-based architecture): MHDR and MEND chunks bookend the datastream, with embedded PNG or JNG images as individual frames and control chunks (DEFI, FRAM, LOOP, ENDL, TERM, BACK, BASI, CLON, PAST, DISC, SHOW) directing playback timing, looping behavior, layer compositing, and memory management. The format supports both full-frame replacement and delta (difference) updates for efficient encoding of animations with static backgrounds, as well as object-based animation where sprites are defined once and repositioned across frames. One advantage is technical sophistication: MNG provides a level of animation control that GIF and APNG cannot match — frame-accurate timing, nested loops, conditional branches, interframe compression, and mixed lossy/lossless content within a single animation. The PNG-based foundation ensures lossless quality with full alpha transparency for each frame. MNG is supported by ImageMagick, GIMP, and various media players, though browser support was limited, which led to APNG's emergence as a simpler alternative for web animation.

Frequently Asked Questions

Why convert SR2 to MNG?

Sony replaced SR2 with ARW years ago, so software support for SR2 is declining — converting to MNG ensures long-term access.

What opens MNG files?

MNG files can be opened with XnView, Konqueror, ImageMagick, and GIMP with MNG plugin support.

Is there quality loss converting SR2 to MNG?

SR2 contains unprocessed sensor data with wide dynamic range. The converter produces MNG output that preserves visual fidelity.

Do I need to pay for SR2 to MNG conversion?

Basic conversions are free for all users. Premium accounts provide extended limits and faster processing speeds.

Are my SR2 files safe during conversion?

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