Show HN: Make your logo extra bright on HDR screens

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!

This is fun and will try to embed it in our project next week.

I just noticed something similar today as an ad where the green oval button was so bright that the rest of the white screen felt grayish/dull than white. It could not be unnoticed playing on the notion that the eye is attracted to the brightest thing on the screen

Please don’t do this.

You know it will be annoying.

The page says it should work on my phone but it doesn't. No difference between the SDR and HDR versions on my phone (S26 Ultra / Chrome).

On the other hand it’s a great signal that whoever uses that is an obnoxious twat and should be plonked.

I do not in fact want sites trying to get around my display preferences to post their visual presence on screen.

It also depends on your screen brightness. In my case, if it’s set to maximum, there is no difference between SDR and HDR.
