Vibrance is a smarter, non-linear saturation control. Where ordinary Saturation multiplies the intensity of every color by the same amount — quickly pushing skies, skin, and already-bright colors past the point they can be displayed, giving that harsh, clipped 'neon' look — Vibrance applies a weighted boost whose absolute lift is strongest for mid-saturation colors and falls off toward both ends. Near-gray and already-vivid pixels change the least, while the muted mid-range colors get the biggest boost. The result is a photo that looks richer and more alive without the cartoonish over-saturation, which is why Vibrance is the go-to 'make it pop' slider in Lightroom and most phone camera apps. This tool gives you both: a Vibrance slider for the protected, non-linear boost and a Saturation slider for a classic even adjustment on top. Drag either to the right to intensify color, or to the left to mute the image down toward grayscale. It works in HSL color space, so only the saturation of each pixel changes — the hue and lightness are preserved, and fully gray pixels stay exactly gray. Everything runs locally on the HTML canvas in your browser: your image is never uploaded, transparency is kept, and there's no sign-up and no watermark.
Vibrance and Saturation, measured on the same photo
| What happens | Saturation +50 | Vibrance +50 |
|---|---|---|
| Colour pushed to the maximum, where its detail is gone | 304,138 pixels of 1,080,000 — 28.16% of the photo flattened. | 0 pixels. Not a rounding-down of a small number: vibrance's lift shrinks to nothing as a colour approaches full saturation, so it cannot push anything over the edge. |
| Colour that was already vivid (0.7 or above, 294,801 pixels here) | Gains 0.147 saturation. | Gains 0.058 — 2.5x less. This is where the two disagree. |
| Colour that was muted (below 0.3, 336,124 pixels here) | Gains 0.105 saturation. | Gains 0.080. The two nearly agree here, which is the opposite of how the difference is usually explained. |
| Gray | Untouched. A pixel with no colour has nothing to multiply. | Untouched, for the same reason. Both sliders at 0 are an exact no-op: 0 of 1,080,000 pixels changed. |
| Hue and brightness | Brightness moves at most 0.5 of 255. Hue moves at most 10 degrees. | Brightness the same 0.5 of 255. Hue at most 5.14 degrees. Neither slider writes a single byte of transparency. |
Measured on a 1200x900 photograph (1,080,000 pixels) run through this page's own code — the same `applyVibranceToData` the browser runs, not a stand-in. Reproduce with scripts/measure-vibrance.mts. The two sliders differ because of one term: saturation multiplies, so its lift grows straight with how saturated a pixel already was, while vibrance adds an amount weighted by s(1-s), which peaks in the middle and falls to zero at both ends. At +50 the lift on a pixel of saturation 0.10 is +0.050 for saturation and +0.045 for vibrance, at 0.50 it is +0.250 against +0.125, and at 0.90 it is +0.100 against +0.045 — except that at 0.75 and 0.90 saturation has already run into the ceiling and stopped, which is what those 304,138 flattened pixels are. So the practical rule is not "vibrance boosts muted colours more"; it does not. It is that vibrance leaves vivid colour alone, and vivid colour is what breaks first. One honest correction to what is usually claimed, this page included until it was checked: hue is not perfectly preserved. Converting to HSL, changing one channel and converting back rounds to whole bytes, and near-gray colours are where a rounding of one unit swings the hue furthest. 5.14 degrees at worst under vibrance, 10 under saturation, and invisible at that size — but measured, not asserted.

Frequently Asked Questions
What's the difference between Vibrance and Saturation?
Saturation multiplies the colorfulness of every pixel by the same factor, so it boosts dull and vivid colors alike — which quickly pushes already-bright colors past the point they can be shown, giving the harsh, clipped 'neon' look. Vibrance applies a weighted boost instead: the lift it adds is strongest for mid-saturation colors and tapers toward both ends, so near-gray and already-vivid colors change little while the muted mid-range gains the most. In short, Saturation is a uniform boost and Vibrance is a protected one — reach for Vibrance when you want richer color without blowing out the brightest, most saturated areas.
Is Vibrance better for portraits and skin tones?
Usually, yes. Because Vibrance adds less boost than a flat Saturation bump to any color that already has some saturation — and eases off further as colors approach full saturation — it's kinder to skin tones and other already-colorful areas, so it adds life to a portrait without turning skin orange or blotchy. A good workflow is to lean on Vibrance for most of the lift and add only a small amount of Saturation if the overall image still looks flat.
Can I use these sliders to mute colors or make a photo grayscale?
Yes. Both sliders work in the negative direction too. Drag Saturation fully to the left to pull every color all the way to grayscale, or part-way for a faded, muted film look. Negative Vibrance eases colors down using the same protective weighting — a fully gray pixel always stays gray — which is handy for toning down an over-colorful image without flattening it completely.
Is my image uploaded, and does it keep transparency?
No upload — Vibrance & Saturation runs entirely in your browser on the HTML canvas, so your image never leaves your device and it works offline once the page has loaded. The adjustment is done in HSL color space and changes only the saturation of each pixel: the hue and lightness are preserved, fully gray pixels stay exactly gray, and the alpha channel is left untouched so transparent areas of a PNG stay transparent. There's no sign-up and no watermark.
