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.

PCT (also known as PICT) is a metafile graphics format originally developed by Apple Computer and introduced alongside the original Macintosh in January 1984. PCT files can contain both vector drawing commands and raster bitmap data, encoded as a sequence of QuickDraw drawing operations — the same graphics primitives used by the Macintosh operating system for all on-screen rendering. The format evolved through two major versions: PICT 1, which recorded basic QuickDraw operations (lines, rectangles, ovals, text, 1-bit bitmaps) in a compact format suitable for the original Macintosh's limited memory, and PICT 2, introduced with Color QuickDraw in 1987, which extended the format to support 24-bit color, multiple color spaces, and embedded JPEG-compressed data. PCT files begin with a 512-byte header (originally used for resource fork information), followed by the picture size, bounding rectangle, and a sequence of opcodes that define the drawing operations. During the Macintosh's commercial ascendancy, PICT was the universal graphics interchange format on Mac OS — the system clipboard used PICT for all graphical copy/paste operations, and most Mac applications could import and export the format. One advantage is the hybrid vector/raster nature: PCT files from the QuickDraw era preserve both scalable drawing commands and pixel data in a single format, enabling resolution-independent output for the vector portions. PICT's historical significance as the native Mac graphics format throughout the classic Mac OS era (1984-2001) provides another dimension. PCT files remain readable by Preview on macOS, ImageMagick, XnView, LibreOffice, and GIMP.

Frequently Asked Questions

Why convert MRW to PCT?

MRW is a discontinued Minolta RAW format — modern software rarely supports it, so converting to PCT is essential for accessing your photos.

What opens PCT files?

PCT files can be opened with macOS Preview (legacy), XnView, IrfanView, and classic Mac applications.

Will the PCT output retain my photo quality?

The converter processes raw image data from MRW and produces a high-quality PCT — results look great for viewing and sharing.

How fast is MRW to PCT conversion?

Conversion typically completes within seconds. Processing happens on cloud servers, so your device stays responsive.

Does Convertio support batch MRW to PCT conversion?

Absolutely. Upload multiple MRW files at once and the converter processes each one to PCT in parallel.

Is my data secure when converting MRW to PCT?

Your privacy is protected — uploaded files are deleted right after processing, and results are purged within 24 hours.
