How Did Wiz Make Its LinkedIn Logo Glow Brighter Than White?
Wiz made its LinkedIn logo appear brighter than the surrounding white interface with an HDR-encoded JPEG carrying a Rec.2020 PQ ICC color profile. HDR displays use that profile to render the white mark above ordinary SDR page white.
The direct answer
The Wiz image is a JPEG with an ICC profile identified as Rec.2020 with PQ transfer. PQ is the absolute-luminance curve used by HDR systems, so selected white pixels can describe more light than an ordinary sRGB image.
The logo did not use #FFFFFF, a blur filter, or a brighter RGB value. Normal web white stops at the top of the SDR range; the HDR image places its white mark above the interface’s reference white.
What the image contains
Its embedded profile is named “Rec2020 Gamut with PQ Transfer.” The JPEG carries the color instructions required for an HDR renderer to interpret the encoded highlights.
Screenshots flatten the display output into SDR, so the physical brightness difference is visible only from the original HDR image.
How it survived LinkedIn
LinkedIn preserved the embedded ICC profile in the image. The profile continued to tell HDR renderers how to interpret the encoded pixels after upload.
How to recreate the effect with Glowhite
Use a white or near-white logo on a dark, flat background. Upload the original artwork to Glowhite, start around 1,000 nits, keep highlight-only mode enabled, and download the verified HDR JPEG. Move that exact file to its destination without taking a screenshot or re-saving it.
Inspect the final hosted version on both HDR and SDR screens. Keep the design legible in SDR and use HDR as the extra layer of luminance.
Frequently asked questions
How did the Wiz logo glow on LinkedIn?
Its JPEG carried HDR-encoded pixels and an embedded Rec.2020 PQ ICC profile, allowing compatible HDR displays to render the white mark above ordinary page white.
Was the Wiz glow a CSS effect or animation?
No. The effect comes from the image pixels and embedded color profile, not CSS or animation.
Can I make the same glowing-logo effect?
Yes. Glowhite creates and verifies the HDR JPEG. Upload the downloaded file directly and test it on HDR and SDR screens.
