About formats

DCR is a proprietary RAW image format developed by Eastman Kodak for their DCS (Digital Camera System) line of professional digital cameras. Introduced in the early 2000s with cameras like the DCS Pro Back and DCS Pro SLR/n, the DCR format captures unprocessed data from Kodak's full-frame CMOS and CCD sensors at 12 to 14 bits per channel, preserving the complete tonal range and color information before any demosaicing, white balance, or tone curve processing is applied. Kodak's DCS cameras occupied a significant niche in professional photojournalism and studio work during the early digital transition, and DCR files from this era represent an important corpus of professional digital imagery. The format stores sensor data alongside Kodak-specific metadata including color matrix coefficients, analogue gain settings, and proprietary noise reduction parameters tailored to each sensor variant. One advantage of DCR is the distinctive color rendering that Kodak's sensor technology and color science produce — many photographers and retouchers consider the tonality of Kodak DCS captures, particularly skin tones and highlight roll-off, to be uniquely pleasing, a characteristic preserved in the RAW data and adjustable during post-processing. Legacy compatibility is another practical strength: despite Kodak's exit from the camera market, DCR files remain supported by Adobe Lightroom, Adobe Camera Raw, dcraw, and RawTherapee, ensuring these early professional digital negatives remain fully accessible for reprocessing with modern algorithms.

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 DCR to HRZ?

DCR is a professional Kodak RAW format with shrinking software support. Converting protects your photographic work from format obsolescence.

What opens HRZ?

Specialized image tools and amateur radio software handle HRZ format images.

Does conversion lose image quality?

Some quality depends on the target format. HRZ uses specialized encoding, so results reflect the characteristics of HRZ output.

Can I batch convert multiple DCR to HRZ?

Upload several DCR images at once. Each one converts to HRZ independently, and you can download them all when finished.

Is it free to convert DCR to HRZ?

Basic DCR to HRZ conversions are free. Paid plans unlock priority processing and expanded capabilities for heavy users.
