- Designers preparing logos for HDR displays
- Worth noticing
- Opaque images become gain-map JPEGs; transparent images use 16-bit PQ PNG because JPEG cannot carry alpha.
Field notes
The controls include automatic and manual HDR-area selection, with adjustments for brightness, colour range, and edge softness. The page distinguishes relative gain-map output for opaque images from absolute-brightness PQ output for transparent images, and lists a 12-megapixel input limit. It says processing stays in the browser; the displayed compatibility list is the site's own guidance.
