About formats

TIFF (Tagged Image File Format) is a flexible raster image format originally developed by Aldus Corporation (later acquired by Adobe) in October 1986 for desktop publishing and scanning applications. The format uses a tagged data structure where the image file header points to one or more Image File Directories (IFDs), each containing a set of tags that describe the image's dimensions, color space, compression, resolution, and other properties. This extensible architecture means TIFF can accommodate virtually any image type: 1-bit bilevel, grayscale, indexed color, RGB, CMYK, CIE L*a*b*, and beyond, at any bit depth from 1 to 64 bits per sample. TIFF supports multiple compression methods including none (uncompressed), LZW, DEFLATE, JPEG, and CCITT Group 3/4 fax compression, as well as multi-page documents, tiled storage for efficient random access to large images, and floating-point pixel values for HDR content. One advantage is professional-grade flexibility — TIFF handles the full range of image types encountered in publishing, prepress, medical imaging, geospatial analysis, and scientific research, where specialized color spaces and high bit depths are required. Lossless archival quality is another core strength: TIFF with no compression or LZW/DEFLATE preserves every pixel value exactly, making it the standard archival format for libraries, museums, and any institution that requires guaranteed long-term image fidelity. TIFF is supported by every major image editing, scanning, and publishing application across all platforms.

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.

Frequently Asked Questions

Why convert TIFF to HRZ?

HRZ is the right choice when you need your TIFF image in a specific format for specialized tools, legacy systems, or particular workflows.

What opens HRZ files?

SSTV software and ham radio tools handle the HRZ format for viewing and processing.

Will the conversion flatten TIFF layers?

If your TIFF contains multiple layers or pages, the conversion produces a flattened HRZ output for maximum compatibility.

Is the output quality good?

Your TIFF image is processed at high quality before encoding into HRZ for maximum fidelity in the output.

Is TIFF to HRZ conversion free?

Standard conversions are free on Convertio. Premium plans offer batch processing and faster speeds.
