Upload a logo, choose which colors should glow, download an HDR JPEG. On HDR screens (such as MacBook Pros and iPhones), the chosen parts shine up to 7.5× brighter than #FFFFFF — everywhere else it's a perfectly normal JPEG. Free. Nothing is stored. #6 on HackerNews 8/22/26.
Certain logos started standing out to me on LinkedIn as brighter/whiter than everything else around them.
I dug in and found out this is accomplished by adding a gain-map to an existing JPEG, visible only on HDR screens like a newer MacBook Pro. LinkedIn is the only social network I've found that isn't stripping them out, but of course you serve them up on your own site.
I worked with Claude Code to turn it into a little browser-based utility (no registration) and hope you find it useful! Or, get your pitchforks and say this is worse than the HTML blink tag.
