Understanding APNG and AVIF 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

AVIF Image

image/avif

AVIF (AV1 Image File Format) is a modern image format based on the AV1 video codec, offering significantly better compression than JPEG and WebP. It supports both lossy and lossless compression, HDR, wide color gamut, alpha transparency, and animated sequences. AVIF is developed as a royalty-free open standard by the Alliance for Open Media.

Advantages

  • Superior compression efficiency, often 50% smaller than JPEG at equivalent quality
  • Supports HDR, wide color gamut (10-bit and 12-bit), and alpha transparency
  • Royalty-free and open standard with growing browser support

Limitations

  • Encoding is significantly slower than JPEG or WebP
  • Not yet universally supported in all browsers and image editors
  • Maximum image dimension limitations in some implementations

Common Uses

  • Next-generation web image optimization for bandwidth savings
  • High-quality HDR image delivery on supporting platforms
  • Progressive replacement for JPEG and WebP in web applications
