About formats

HDR (also known as RGBE or Radiance HDR) is a high-dynamic-range image format created by Greg Ward Larson as part of the Radiance) lighting simulation system, developed at Lawrence Berkeley National Laboratory starting in 1985 with the HDR format emerging around 1989. The format stores floating-point RGB pixel values using a compact 32-bit-per-pixel encoding called RGBE (Red, Green, Blue, Exponent): three 8-bit mantissa bytes share a single 8-bit exponent, representing luminance values across a range of roughly 76 orders of magnitude while keeping file sizes comparable to standard 24-bit images. HDR files begin with a text header containing rendering and exposure metadata, followed by the RGBE pixel data compressed with a scanline-oriented run-length encoding scheme. The format captures the full luminance range of real-world scenes — from deep shadows to direct sunlight — enabling physically accurate lighting calculations, tone mapping to different display conditions, and post-capture exposure adjustment without the clipping artifacts inherent in 8-bit formats. One advantage is the format's foundational role in HDR imaging: Radiance HDR pioneered the concept of storing real-world luminance values in image files, and the .hdr format became the standard for light probe images and environment maps used in image-based lighting across the 3D rendering industry. The format's compact encoding is another practical strength — the RGBE scheme provides far more dynamic range than 8-bit formats while using only 33% more storage per pixel, a favorable tradeoff that made HDR practical on storage-limited systems of the late 1980s. HDR files are supported by Photoshop, GIMP, ImageMagick, Blender, and all major 3D renderers.

IPL (IPLab) is a scientific image format developed by Scanalytics (later acquired by BD Biosciences) for their IPLab scientific image analysis software, first released around 1988. The format was designed to store microscopy and scientific imaging data with the precision and metadata needed for quantitative analysis in biological and biomedical research. IPL files support multiple data types including 8-bit and 16-bit unsigned integers, 16-bit signed integers, and 32-bit floating-point pixel values, accommodating the wide dynamic ranges produced by fluorescence microscopes, CCD cameras, and other scientific imaging instruments. The format handles multi-dimensional datasets including Z-stacks (focal series through a specimen), time-lapse sequences, and multi-channel fluorescence acquisitions where each channel captures emission from a different fluorescent probe. IPL files include a header with image dimensions, data type, number of planes, spatial calibration (pixels-to-micrometers conversion), and acquisition metadata from the microscope system. One advantage is quantitative integrity: unlike photographic formats that apply gamma correction, compression, or color space transforms, IPL preserves the raw linear intensity values from the detector, ensuring that measurements of fluorescence intensity, optical density, or particle counts performed on the image data correspond directly to the physical quantities being measured. The format's role in the microscopy community is another practical consideration: IPLab was widely used in cell biology, neuroscience, and pathology labs throughout the 1990s and 2000s, and archived IPL datasets from published research remain scientifically valuable. IPL files can be read by ImageJ/FIJI, Bio-Formats, and ImageMagick.

Frequently Asked Questions

Why convert HDR to IPL?

HDR captures full luminance range, but standard screens need tonemapped output. IPL gives you a display-ready version.

What programs open IPL files?

ImageMagick and specialized Scanalytics imaging tools open IPL scientific image data

Does this converter work on mobile devices?

Absolutely. The browser-based converter runs on phones and tablets — iOS, Android, or any device with a modern browser handles it fine.

Are colors preserved in the HDR to IPL conversion?

HDR stores extended dynamic range data. Converting to IPL maps that range into the displayable gamut while retaining visual accuracy.

How fast is HDR to IPL conversion?

Most conversions complete within seconds. Larger or more complex files may take slightly longer, but processing happens on fast cloud servers.

Is tonemapping applied during conversion?

When converting Radiance HDR luminance data to a displayable format like IPL, tonemapping maps the full range into visible output.
