HDR Glow for LinkedIn and Social Posts
SDR white on your screen is mapped to a comfortable reference level — roughly 200 nits — while HDR panels can output 1000+ nits in headroom. This tool re-encodes your image with a Rec.2100 PQ ICC profile so bright pixels signal the display to use that headroom. On an HDR MacBook or iPhone, a white logo can visibly out-glow the white feed chrome.
Use subtle defaults (1000 nits, highlights only) for professional posts. Avoid full-frame flashbangs — the feed tunes out abuse.
