JPEG to HDR PNG Converter

Convert JPEG photos to HDR PNG using local, in-browser processing. Adjust boost and look controls, then export with HDR metadata.

How Supernova Handles This Format

JPEG images are decoded into linear light, transformed to BT.2020, and encoded with PQ transfer for HDR output. This workflow preserves detail while allowing controlled highlight brightness.

  • 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.
