About formats

MAP is an internal raster image format used by ImageMagick, the open-source image processing suite first released by John Cristy at DuPont on August 1, 1990. MAP files store indexed-color (color-mapped) images in ImageMagick's native representation: a color palette (the map) followed by pixel data where each pixel is an index into that palette rather than a direct RGB value. The format provides a compact representation for images with a limited number of distinct colors — each pixel requires only enough bits to index the palette (typically 8 bits for up to 256 colors), compared to the 24 or 32 bits per pixel required by full-color formats. MAP serves primarily as an intermediate format within ImageMagick's processing pipeline, useful when performing operations that benefit from or require palettized representation: color quantization (reducing an image to a specific number of colors), palette manipulation, GIF preparation, and indexed-color analysis. The format is invoked through ImageMagick's standard I/O syntax and can be piped between processing stages without disk overhead. One advantage is direct access to ImageMagick's color quantization and palette management capabilities: MAP format output makes the palette structure explicit and manipulable, enabling workflows where specific palette operations (reordering, remapping, merging) need to be performed between processing steps. The format's integration into the ImageMagick processing ecosystem is another practical strength — any of ImageMagick's extensive image manipulation operations can consume or produce MAP format data, making it a natural intermediate for color-reduction pipelines that ultimately target GIF, PNG with palette, or other indexed-color formats.
Initial release: 1990
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.

Frequently Asked Questions

Why convert MAP to EXR?

High dynamic range for VFX and film production — converting MAP to EXR gives your color maps broader reach and easier sharing across standard platforms.

What programs open EXR?

Any modern image viewer opens EXR — Windows Photos, macOS Preview, GIMP, Photoshop, and web browsers all support it.

What is the MAP format?

MAP is used in image processing and color palette management. It stores color lookup tables and image processing pipelines — converting to EXR makes this data universally accessible.

How long does the conversion take?

Most MAP to EXR conversions finish within seconds. Larger or more complex images may take slightly longer depending on the data size.

Can I batch convert MAP to EXR?

Yes — Convertio supports batch uploads. Add multiple MAP images and convert them all to EXR at once to speed up your workflow.

Does this work on mobile devices?

Yes — the converter runs in any web browser, so it works on phones, tablets, laptops, and desktops regardless of operating system.
