About formats

HRZ is a simple raster image format associated with slow-scan television (SSTV), a method of transmitting still images over radio frequencies used by amateur radio operators since the late 1950s when Copthorne Macdonald pioneered the technology. HRZ files store images at a fixed resolution of 256x240 pixels in raw RGB format, with each pixel represented as three bytes (red, green, blue) at 8 bits per channel, producing uncompressed files of exactly 184,320 bytes. The format has no header, no metadata, and no compression — the file is simply a sequential dump of raw pixel data in row-major order. This extreme simplicity reflects the format's origins in the amateur radio community, where SSTV images are transmitted as audio tones encoding luminance and chrominance values over narrow-bandwidth HF (shortwave) radio channels. The fixed 256x240 resolution corresponds to common SSTV transmission modes, and HRZ files serve as the digital capture or storage medium for received SSTV transmissions. One advantage is the format's zero-overhead structure: with no parsing, decompression, or metadata processing required, HRZ files can be read by any program capable of reading raw pixel data with known dimensions — a single function call in virtually any programming language. The format's connection to amateur radio SSTV culture is another notable aspect: HRZ files document a unique form of image communication where operators transmit photographs over thousands of miles using nothing but radio waves and audio encoding, a practice that continues today alongside digital modes. HRZ files can be opened by ImageMagick, GIMP, and specialized SSTV software.

PS is the standard extension for files written in PostScript, the page description language created by Adobe Systems and first shipped in 1984 with the Apple LaserWriter. A PostScript file is a complete program that describes the precise appearance of a page — text, vector graphics, curves, fills, and even embedded raster images — using a stack-based interpreted language with full programming constructs. When sent to a PostScript-compatible printer or interpreter (such as Ghostscript), the program executes and produces rendered output. PostScript introduced cubic Bezier curves as the standard representation for smooth outlines, a mathematical model that became the foundation for virtually all subsequent vector graphics and font technology including PDF, SVG, and OpenType. The language also serves as a font format: Type 1 PostScript fonts encode glyph outlines as PostScript programs with hinting instructions for sharp rendering at low resolutions, while Type 3 fonts use the full language to define arbitrarily complex glyphs. One advantage is device independence — a PostScript file produces identical output whether rendered on a 300 dpi desktop printer, a high-resolution imagesetter, or a software rasterizer, because it describes shapes mathematically rather than as pixel grids. The human-readable text format provides another practical strength: PS files can be inspected, debugged, and modified with any text editor, and they can be generated programmatically by any software without requiring specialized libraries. PostScript files are widely handled by Ghostscript, Adobe Acrobat, preview applications, and numerous publishing and graphics tools.

Frequently Asked Questions

Why convert HRZ to PS?

HRZ requires niche software to open. Converting to PS lets you share and view your SSTV images on virtually any platform.

What programs open PS?

Vector editors like Adobe Illustrator, Inkscape, CorelDRAW, and Affinity Designer open PS. Some office suites import it too.

What is the HRZ format?

HRZ is used in amateur radio slow-scan television. It stores radio-transmitted images and ham radio communication — converting to PS makes this data universally accessible.

Can I convert multiple HRZ images at once?

Yes — upload several HRZ images in one session and convert them all to PS simultaneously. Batch processing saves significant time.

What platforms are supported?

The converter works on any device with a browser — Windows, macOS, Linux, iOS, Android. No platform-specific software needed.

Is the output quality comparable?

The conversion extracts the best possible quality from your HRZ data. The PS output reflects the format's capabilities accurately.
