HRZ is an image format for slow-scan television (SSTV), used by amateur radio operators to transmit images over radio.
UYVY is a YUV 4:2:2 packed pixel format commonly used in video capture and processing.
FreeFileConvert uses tuned encoding for HRZ to UYVY conversions, preserving clarity while trimming file size. Finished images open instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload HRZ files from desktop or tablet, queue multiple jobs, and let the converter finish autonomously. Return whenever convenient to download synchronized UYVY results on any device you rely on.
Process up to 5 files sized 1024 MB per batch without splitting queues manually. Mixed-format uploads convert together, producing consistent UYVY images with dependable progress tracking.
HRZ files contain low-resolution images optimized for transmission over narrow-bandwidth radio channels.
UYVY stores color data as U0Y0V0Y1 sequences, halving horizontal chroma resolution.
