SoVeryBright - Make your logo brighter than white on HDR screens
Show HN: Make your logo extra bright on HDR screens
SoVeryBright is a free web tool that lets you upload a logo and create an HDR JPEG with glowing highlights, making chosen colors shine up to 7.5× brighter than pure white on HDR displays. It uses ISO 21496-1 gain maps for web and BT.2100 PQ for LinkedIn, while remaining a perfectly normal JPEG on other screens. The tool automatically selects light elements for best effect, and also demonstrates how to achieve brighter-than-white text using CSS background-clip. No files are stored, and it works in Chrome 137+, Safari 26, and iOS 26.
On HDR screens the chosen parts shine up to 7.5× brighter than #FFFFFF. Everywhere else it's a perfectly normal JPEG.
