Convert PPM to HRZ
Convert PPM images to HRZ format, edit and optimize images online and free.
The PPM which stands for Portable Pix-Map is a simple structured RGB raster image format designed by Jef Poskanzer in the 1980s. It was designed to easily exchange binary images between different platforms.
The HRZ file extension is integral to Slow Scan Television (SSTV), a digital imaging technique used in amateur radio to transmit images via radio waves. The HRZ format efficiently stores images in a 256 x 240 RGB bitmap, making it ideal for low-bandwidth transmissions. SSTV encodes images into audio signals, which are then decoded back into visual files, producing an HRZ file. This technology is crucial for image communication in bandwidth-constrained environments.
