Understanding JPEG and EXR Formats

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

Source Format

JPEG Image

image/jpeg

JPEG is identical to JPG and refers to the same lossy image compression standard developed by the Joint Photographic Experts Group. The .jpeg extension is the full-length version of the file extension, while .jpg originated from the three-character limit of early Windows file systems. Both extensions produce and read the exact same file format.

Advantages

  • Excellent compression ratio for photographic images, resulting in small file sizes
  • Universally supported across virtually all devices, browsers, and software
  • Adjustable quality level allows fine control over the size-quality tradeoff

Limitations

  • Lossy compression degrades image quality with each re-save
  • Does not support transparency (alpha channel)
  • Poor choice for images with sharp edges, text, or flat colors due to compression artifacts

Common Uses

  • Digital photography and camera output
  • Web images and social media sharing
  • Email attachments and document embedding

Target 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
