The effect is in the image.
A conventional glow effect paints a soft edge around a shape. HDR can make the shape itself brighter on a capable screen. Both may look luminous, but they work differently.
Glowhite uses the second approach: it converts artwork into an HDR JPEG with a Rec.2020/PQ color profile. There is no animation or CSS effect required in the exported file.
What a brand example can—and cannot—show.
A glowing brand mark can be an interesting reference. But without the original file and a reproducible test, its exact production method is uncertain. We do not present Wiz or another brand as a verified example of Glowhite’s workflow.
The useful lesson is the underlying technique. A screenshot or an unusually bright mark is not enough to identify a specific profile or prove that a social platform will preserve it for everyone.
Try the principle on your own artwork.
Use a white symbol on black. Compare an ordinary export with a Glowhite version on a known HDR setup. Begin with moderate brightness and keep the shape legible without the extra light.
Then test the destination. Platforms can resize, re-encode or display assets differently. Your own published result is a better guide than a promise based on someone else’s screenshot.
