Understanding APNG and EXR Formats

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

Source Format

Animated PNG

image/apng

APNG (Animated Portable Network Graphics) is an extension of the PNG format that enables frame-based animation similar to GIF but with full 24-bit color and 8-bit alpha transparency. It was developed by Mozilla and stores animation frames as additional PNG chunks within the file. APNG files degrade gracefully in applications that do not support animation, displaying the first frame as a static PNG.

Advantages

  • Full 24-bit color and 8-bit alpha transparency in animated images
  • Backwards compatible with static PNG viewers showing the first frame
  • Significantly better visual quality than GIF for animated content

Limitations

  • Larger file sizes than GIF for simple animations with few colors
  • Not an official W3C standard, though widely supported in browsers
  • Limited tooling and editor support compared to GIF

Common Uses

  • High-quality animated stickers and emojis
  • Animated web graphics requiring transparency and full color
  • Animated favicons and UI elements with smooth gradients

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
