What is so very bright?
so very bright is a web-based image converter that transforms JPEGs into HDR (High Dynamic Range) format using ISO 21496-1 gain maps and ICC profiles. Makes whites, bright colors, and text appear to glow on HDR displays while remaining normal JPEGs on standard displays. Upload a logo, choose colors to glow, download HDR JPEG — up to 7.5× brighter than #FFFFFF on HDR screens.
so very bright pricing
Pricing model: Freemium
so very bright pros
- Files remain backward compatible—render as normal JPEGs on non-HDR displays with no visual degradation
- Supports multiple export formats including HDR JPEG, LinkedIn PQ, and standalone gain maps
- Can brighten text beyond pure white (#FFFFFF) on HDR displays using CSS background-clip technique with media query gating
- Automatic white detection for simple use cases; manual color selection for brand colors and accents
so very bright cons
- Only visible to HDR displays in supported browsers (Chrome 137+, Safari 26+, iOS 26, Apple Photos, LinkedIn); most platforms strip or normalize HDR data
- Dark colors cannot effectively glow—boosting them appears as washed-out neon rather than luminance
- Text rendering at full brightness (1,500 nits) can be visually hostile; CSS background-clip method clips overflowing text
Frequently asked questions about so very bright
What happens when HDR-enhanced images are viewed on non-HDR displays?
Files render as normal JPEGs with no visual changes. The gain map is simply ignored. Nothing breaks.
Which colors work best for the glowing effect?
Light, near-white elements on dark backgrounds work best. The measured sweet spot is +2.9 stops (~1,500 nits). Dark colors should not be boosted as they appear as washed neon instead of luminant.
Can this work with text on web pages?
Yes, using `background-clip: text` with an HDR JPEG gain-map on HDR displays. SDR browsers and Firefox see a regular `color` fallback, preventing clipping issues.
What is the file format and how large are the files?
ISO 21496-1 gain-map JPEGs with an embedded grayscale image. Gain maps add minimal overhead (~1.3 KB for a white swatch) and are supported natively by modern browsers.
