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
JP2 (JPEG 2000 Part 1) is an image format based on the JPEG 2000 compression standard, developed by the Joint Photographic Experts Group and published as ISO/IEC 15444-1 in December 2000 as the successor to the original JPEG standard. Unlike JPEG's block-based discrete cosine transform, JPEG 2000 uses discrete wavelet transform (DWT) compression, which eliminates the characteristic 8x8 block artifacts visible in highly compressed JPEG images and instead produces a smooth, gradual quality degradation. The format supports both lossy and lossless compression within the same codestream, along with features absent from original JPEG: 16-bit and higher bit-depth images, arbitrary numbers of color channels, alpha transparency, region-of-interest coding (allocating more bits to important areas), and progressive quality or resolution refinement from a single compressed stream. One advantage is superior image quality at low bit rates — JPEG 2000 produces visibly cleaner images than JPEG at equivalent file sizes, particularly below 0.5 bits per pixel where JPEG exhibits severe blocking. The progressive decoding capability is another strength: a single JP2 file can be decoded at any resolution or quality level without encoding multiple versions, valuable for remote sensing and medical imaging where the same image must serve both thumbnail browsing and full-resolution analysis. JP2 is the mandated format for digital cinema (DCI), the preferred format in geospatial data (GeoJP2), and widely adopted in cultural heritage digitization.

Frequently Asked Questions

Why convert MRW to JP2?

Legacy MRW files from Konica Minolta DSLRs need conversion to JP2 to work with current editing software and sharing platforms.

What opens JP2 files?

JP2 files can be opened with IrfanView, XnView, Adobe Photoshop, GIMP with plugins, and some web browsers.

How long does MRW to JP2 conversion take?

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

How does quality compare between MRW and JP2?

MRW stores raw sensor data — the converter extracts maximum quality and renders it into JP2 with excellent visual results.

Does Convertio support batch MRW to JP2 conversion?

Absolutely. Upload multiple MRW files at once and the converter processes each one to JP2 in parallel.

Are my MRW files safe during conversion?

Uploaded MRW files are deleted immediately after conversion. JP2 outputs are automatically removed within 24 hours.
