About formats

MRW is the proprietary RAW image format developed by Minolta (later Konica Minolta) for their digital SLR and advanced compact cameras, introduced in 2001 with the DiMAGE 7, one of the first consumer-grade digital cameras to offer RAW capture alongside JPEG. MRW files capture the unprocessed 12-bit readout from the camera's CCD sensor in its native Bayer mosaic pattern, storing the data in a container format with a series of tagged data blocks for the raw image, camera settings, and proprietary metadata. The format was used across Minolta's digital camera lineup including the DiMAGE A-series advanced compacts and the Dynax/Maxxum 5D and 7D digital SLRs — the latter being the first DSLRs with built-in sensor-shift image stabilization, a technology later inherited by Sony when they acquired Konica Minolta's camera division in 2006. MRW files preserve the original sensor values needed for high-quality demosaicing, custom white balance, and exposure adjustment, giving photographers flexibility unavailable with the camera's in-body JPEG processing. One advantage is historical technological significance: MRW files from the Dynax 7D and its predecessors document the pioneering implementation of in-body stabilization and other innovations that became industry standards, and the RAW data preserves these early captures in their most flexible form. Continued compatibility is another strength — MRW files are supported by Adobe Lightroom, dcraw, LibRaw, RawTherapee, and other modern RAW converters, keeping these Minolta-era digital negatives fully usable with current processing algorithms.
Developer: Minolta
Initial release: 2001
CGM (Computer Graphics Metafile) is a vector graphics standard defined by ISO 8632, first published in 1987 and developed through the ISO/IEC JTC 1/SC 24 committee. The standard defines a device-independent format for storing and transferring two-dimensional vector graphics, raster images, and text. CGM supports three encoding methods: character encoding (compact text representation), binary encoding (efficient machine-readable form), and clear-text encoding (human-readable for debugging). The format describes graphical primitives including polylines, polygons, ellipses, circular arcs, splines, and text with associated attributes for color, line style, fill patterns, and clipping boundaries. CGM found its strongest adoption in technical documentation, particularly in aerospace, defense, and industrial sectors where long-term archival and precise technical illustration are critical. One advantage is formal standardization — as an ISO standard, CGM provides vendor-neutral, specification-driven interoperability guaranteed across compliant implementations. The format's adoption in specialized industries is another practical strength: WebCGM, a W3C profile of CGM, became the mandated illustration format for interactive electronic technical manuals in the aerospace industry (ATA iSpec 2200), ensuring CGM's continued relevance in aviation maintenance documentation. While general-purpose vector work has moved to SVG and PDF, CGM persists in regulated industries where certified, standards-based graphics interchange is mandatory.

Frequently Asked Questions

Why convert MRW to CGM?

Minolta stopped making cameras years ago, so MRW files risk becoming inaccessible — converting to CGM future-proofs your photo archive.

What opens CGM files?

CGM files can be opened with WebCGM viewers, technical illustration tools, and engineering documentation software.

Is there quality loss converting MRW to CGM?

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

Are my MRW files safe during conversion?

Uploaded MRW files are deleted immediately after conversion. CGM outputs are automatically removed within 24 hours.

Is batch conversion available for MRW to CGM?

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

Is MRW to CGM conversion free on Convertio?

Standard conversions are available for free. Premium plans unlock higher capacity and priority processing for heavy use.
