Understanding APNG and ARW 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

Sony Raw Image

image/x-sony-arw

ARW (Alpha Raw) is Sony's proprietary raw image format used by Sony Alpha mirrorless and DSLR cameras. Based on the TIFF specification, it stores unprocessed 12-bit or 14-bit sensor data with complete metadata. ARW files can be either uncompressed or use Sony's lossy or lossless compressed raw encoding.

Advantages

  • Preserves full unprocessed sensor data for maximum post-processing latitude
  • Supports both compressed and uncompressed raw storage options
  • Well-supported by major photo editing applications including Lightroom and Capture One

Limitations

  • Proprietary format with no publicly available specification
  • Large file sizes, especially in uncompressed mode
  • Requires raw-capable software for viewing and editing

Common Uses

  • Professional photography with Sony Alpha series cameras
  • Raw photo editing and non-destructive development
  • High-quality archival of photographic captures
