WebP to HDR PNG Converter

Turn WebP images into HDR PNG files without sending data to a server. Supernova gives you live before/after editing and final HDR export.

How Supernova Handles This Format

WebP inputs follow the same calibrated pipeline as other formats: decode, linear grading controls, HDR boost mapping, PQ encoding, and metadata packaging for compatible HDR displays.

  • 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.
