HDR PNG Browser Compatibility

HDR PNG display support depends on browser color management and metadata handling. Supernova exports cICP, cHRM, and iCCP for broad compatibility.

Implementation Notes

  • Chrome and Edge use cICP signaling for HDR rendering.
  • Safari on macOS uses ICC metadata for EDR display behavior.
  • On SDR displays, files still render as standard PNG images.
