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.

BMP (Bitmap) is a raster image file format developed by Microsoft for the Windows operating system, introduced with Windows 3.0 in 1990. The format stores pixel data in a straightforward structure: a file header specifying dimensions, color depth, and compression method, followed by an optional color palette and then the raw pixel array. BMP supports color depths from 1-bit monochrome through 4-bit and 8-bit indexed color to 16-bit, 24-bit true color, and 32-bit with alpha channel. Most BMP files store pixels uncompressed (BI_RGB), though optional RLE compression is available for 4-bit and 8-bit modes. Pixels are arranged in bottom-up row order by default, with each row padded to a 4-byte boundary. One advantage is absolute simplicity — the format has no complex encoding, filtering, or compression layers, making BMP files trivial to read and write programmatically in any language. This simplicity also means BMP images render with zero decoding overhead, useful in scenarios where decompression latency matters. The format's deep Windows integration is another strength: BMP is the native bitmap format for Windows GDI, clipboard operations, and device-independent bitmap (DIB) handling, ensuring first-class support across the entire Windows ecosystem. While BMP's lack of compression produces large files unsuitable for web use or storage-constrained environments, it remains widely used as an intermediate format in image processing, as a clipboard exchange format, and in embedded systems where decoding simplicity outweighs file size.

Frequently Asked Questions

Why convert MRW to BMP?

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

What opens BMP files?

BMP files can be opened with Windows Paint, Photos, GIMP, Adobe Photoshop, IrfanView, and any image viewer on Windows.

Are my MRW files safe during conversion?

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

Does MRW to BMP work on Mac and Linux?

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

Will the BMP output retain my photo quality?

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