Technical note

Before you convert ARW to STEP

ARW files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to STEP bakes those decisions into the pixels, and highlight recovery is no longer available afterwards. Set white balance and exposure before the run rather than after. ARW is made of pixels and STEP is a geometry format, so the two describe shape in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains usable geometry or a picture placed inside a STEP container.

My Sony A7III produces ARW files that choke my old PC. reaConverter lets me convert them to JPEG with lossless compression, reducing file size by 70% while keeping all the details. Now I can store more photos without upgrading my hardware.

I use reaConverter to convert ARW files to PNG for my digital art projects. The transparency support is great, and the colour depth is preserved perfectly. It's the only converter I've found that handles Sony's uncompressed RAW format without issues.

Sony's ARW files are great, but they're a pain to share. reaConverter turns them into JPEGs that look exactly like the original – no colour shifts, no sharpness loss. I've tried Capture One and Lightroom, but this is faster and more straightforward for batch conversions.

I had to convert 1,500+ ARW files from a fashion shoot to TIFF for the client. reaConverter did it overnight without a single error. The output was flawless – perfect colours and full resolution. This software is incredibly robust.
