Understanding EXR and BMP Formats

Learn about the source and target file formats to understand what happens during conversion.

Source Format

OpenEXR Image

image/x-exr

OpenEXR is a high dynamic range raster image format developed by Industrial Light & Magic for use in visual effects and motion picture production. It supports 16-bit and 32-bit floating-point pixels, multiple compression methods, arbitrary image channels, and multi-part files. OpenEXR is the industry standard for storing intermediate and final rendered frames in VFX pipelines.

Advantages

  • Industry-standard 16-bit and 32-bit floating-point precision for VFX work
  • Supports an arbitrary number of named channels and deep image data
  • Multiple lossless and lossy compression options including PIZ and DWAA

Limitations

  • Large file sizes even with compression, especially for 32-bit data
  • Not supported by web browsers or most consumer image viewers
  • Complex format specification requires specialized libraries to read and write

Common Uses

  • Visual effects compositing and intermediate renders in film production
  • 3D rendering output for lighting and shading passes
  • HDR image storage for professional color grading and post-production

Target Format

BMP Image

image/bmp

BMP (Bitmap) is an uncompressed or minimally compressed raster image format developed by Microsoft. It stores image data pixel by pixel with no quality loss, supporting color depths from 1-bit monochrome to 32-bit with alpha. BMP files are typically very large because most implementations store raw pixel data without compression.

Advantages

  • Completely lossless with no compression artifacts
  • Simple format that is fast to read and write
  • Native support in all Windows applications

Limitations

  • Very large file sizes due to lack of effective compression
  • Not suitable for web use due to excessive file sizes
  • Limited metadata support compared to modern formats

Common Uses

  • Windows system graphics and clipboard operations
  • Intermediate format in image processing pipelines
  • Legacy application compatibility
