VIFF (Visualization Image File Format) is an image format developed by Khoros for scientific visualization.
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 VIFF to HRZ conversions, preserving clarity while trimming file size. Finished audio streams instantly across phones, tablets, desktops, and modern browsers without extra tweaks.
Upload VIFF 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.
VIFF supports multiple bands, data types, and machine-independent binary format.
HRZ files contain low-resolution images optimized for transmission over narrow-bandwidth radio channels.
Upload your image file in the VIFF format from your device, Dropbox, or Google Drive.
Select HRZ as the output format and click Convert. Adjust optional settings if needed.
Download the converted image file. Each file stays available for up to 5 downloads.
