NRW is a RAW image format used by some Nikon Coolpix cameras.
HRZ is an image format for slow-scan television (SSTV), used by amateur radio operators to transmit images over radio.
FreeFileConvert uses tuned encoding for NRW to HRZ conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload NRW files from desktop, tablet, or cloud storage, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized HRZ results on any device you rely on.
Process up to 5 files sized 1000 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent HRZ audio with dependable progress tracking.
NRW files contain uncompressed sensor data similar to NEF but from compact cameras.
HRZ files contain low-resolution images optimized for transmission over narrow-bandwidth radio channels.
Upload your image file in the NRW format from your device, Dropbox, or Google Drive.
