About formats

EXR is a high-dynamic-range raster image format developed by Industrial Light & Magic (ILM) internally since 1999 and publicly released as open-source software in January 2003. OpenEXR was created to meet the demanding requirements of feature film visual effects compositing, where scenes routinely contain extreme brightness ranges — from deep shadows to specular highlights on water, metal, or light sources — that exceed the precision of 8-bit or 16-bit integer formats. EXR stores pixel data in 16-bit floating-point (half) or 32-bit floating-point per channel, providing over 30 stops of dynamic range with smooth precision across the entire luminance spectrum. The format supports an arbitrary number of channels (not just RGBA), tiled and scanline storage, multiple compression methods (lossless ZIP, lossy B44 and DWAA/DWAB for preview quality), multi-part files containing multiple views or layers, and deep pixel data where each pixel stores multiple depth-sorted samples for volumetric effects. One advantage is compositing fidelity: the floating-point precision means that color grading, exposure adjustments, lighting changes, and multi-layer compositing operations produce mathematically correct results without the banding, clipping, or quantization artifacts inherent in integer formats. EXR's adoption as the VFX industry standard is another core strength — it is the default interchange format for Foundry Nuke, Autodesk Flame, Blackmagic Fusion, Adobe After Effects, and every major 3D renderer, and its open-source C++ library is embedded in hundreds of production tools.
Initial release: January 2003
XPM (X PixMap) is a color image format for the X Window System, developed by Arnaud Le Hors at GROUPE BULL beginning in 1989 as the color successor to the monochrome XBM format. Like XBM, XPM files are valid C source code — each file defines the image as a static array of character strings, where the header strings specify width, height, number of colors, and characters per pixel, the color definition strings map character codes to color values (supporting X11 color names, hexadecimal RGB, and symbolic color types like 'background' and 'foreground'), and the pixel strings encode each row as a sequence of character codes that index the color palette. This ASCII art representation makes XPM images human-readable: one can often see the image content directly in the text of the source file. The format went through three revisions: XPM1 (1989, compatible with X10), XPM2 (simplified syntax), and XPM3 (1991, the current version with the static char* syntax and extended color specification). XPM was the standard format for X Window application icons, splash screens, pixmap buttons, and themed UI elements throughout the 1990s and 2000s. One advantage is the combined benefits of being a valid C source file and a color image: XPM files can be compiled into applications, edited in any text editor, processed by text tools, and version-controlled, while supporting up to 256 colors with transparency (using the 'None' color keyword). The X11 ecosystem's reliance on XPM ensures broad tool support. XPM files are handled by all X11 toolkits, ImageMagick, GIMP, and web browsers (legacy support).
Initial release: 1989

Frequently Asked Questions

Why convert EXR to XPM?

EXR stores HDR data that standard viewers cannot display. Converting to XPM produces a tonemapped version anyone can view.

What programs open XPM files?

GIMP, ImageMagick, XnView, and X Window System tools open XPM text-based pixel map images

How many EXR files can I convert at once?

You can upload multiple EXR files in one session. Each converts to XPM separately, and all results are downloadable upon completion.

How fast is EXR to XPM conversion?

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

Are uploaded EXR files stored permanently?

No. Source files are deleted immediately after processing, and converted outputs are purged from servers within 24 hours automatically.

What platforms support the EXR to XPM converter?

Any device with a web browser — Windows, macOS, Linux, Chrome OS, iOS, and Android. No app installation is needed.
