Your post. But glowing.

Superwhite pushes your image's whites into the screen's HDR headroom — physically brighter than the feed around it. Here's the same logo, posted twice:

Post image with Superwhite, glowing brighter than white

Your display is SDR — this is a simulation of the effect. On HDR screens the glow is real.

Same pixels, same feed. The right one is a real HDR file — on this display it's glowing above the page's white right now.

This panel is pure white on purpose — on an HDR display the right image should visibly out-glow it.

How it works

Your image gets re-encoded with a Rec.2100 PQ color profile — the signal HDR video uses. Browsers and apps on HDR-capable screens (recent MacBooks, iPhones, Pixels) render the bright parts using the display's extra brightness reserve, above normal white. Everything happens locally in your browser.

Where it survivesLinkedIn feed posts, as a JPEG, uploaded directly. Don't crop or edit in the composer — that strips the profile.
Where it diesScreenshots, re-saving in editors, WhatsApp/iMessage compression, and copy-paste. Move the file itself.
Who sees itOnly people on HDR displays with battery saver off. Everyone else sees a normal image — slightly dimmer whites, no harm done.
Best inputHigh-contrast graphics: logos, wordmarks, simple illustrations. Photo gradients can band at 8-bit.
