What it does
RAW in. Smaller RAW out.
RRAWK compresses and resizes supported Nikon RAW video on your PC — without baking to conventional rendered video.
Resize while staying RAW
Create a smaller-resolution RAW file instead of converting your footage to conventional rendered video.
Native preview
Preview supported RAW clips directly inside RRAWK.
GPU acceleration
NVIDIA CUDA and AMD acceleration on validated routes, with CPU processing where applicable.
Your footage stays on your PC.RRAWK processes supported RAW footage locally. Core preview and conversion work without an Internet connection.

Quality modes
Lossless · Pure · Prime
Public V1 qualities are exactly these three. Availability depends on the supported source workflow.
Lossless
Keep the supported Source RAW coefficients unchanged while reducing file overhead.
Available only for specific supported Source workflows. Not a resize path.
Pure
Higher quality with moderate storage savings.
Prime
Stronger compression for much smaller RAW files while keeping the RAW workflow.
Performance
GPU when it helps. CPU when it must.
Acceleration depends on camera, source format, and output mode. Not every workflow is GPU-accelerated on every vendor.
NVIDIA CUDA
Hardware acceleration is available for supported NVIDIA workflows.
AMD
AMD GPU acceleration is available on validated routes. Availability depends on camera, source format, and output mode.
CPU
CPU processing remains available where applicable.
In selected validated AMD Source tests on Radeon RX 7600 XT, RRAWK reached up to ~8× faster than CPU. Results are route-dependent; actual performance varies with hardware, source, and mode.
