AVIF to HDR PNG Converter

Convert AVIF to HDR PNG and keep full local privacy. Tune saturation, vibrance, contrast, and highlight roll-off before downloading.

How Supernova Handles This Format

AVIF images are processed in-browser and exported as 16-bit HDR PNG with cICP, cHRM, and iCCP metadata. This improves compatibility for HDR PNG workflows while preserving the HDR intent.

  • Process locally in your browser with no uploads.
  • Preview edits with a fast SDR approximation.
  • Export 16-bit HDR PNG using PQ and BT.2020 metadata.
