Understanding PNG and EXR Formats

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

Source Format

PNG Image

image/png

PNG (Portable Network Graphics) is a lossless raster image format that supports full alpha transparency. It was created as a patent-free replacement for GIF and uses DEFLATE compression to reduce file sizes without any loss of quality. PNG is ideal for images that require transparency or need to be edited repeatedly without degradation.

Advantages

  • Lossless compression preserves perfect image quality
  • Supports full alpha transparency with 256 levels of opacity
  • Excellent for graphics with sharp edges, text, and flat colors

Limitations

  • Significantly larger file sizes compared to JPEG for photographic images
  • Does not support animation in standard implementations
  • Not ideal for print workflows that expect CMYK color space

Common Uses

  • Web graphics, logos, and icons requiring transparency
  • Screenshots and user interface elements
  • Graphics with text overlays or sharp geometric shapes

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
