RGB To Hex
RGB to Hex without uploading it
Type three channels from 0 to 255 and this page shows the hex code, CSS rgb(), HSL, HSV, relative luminance and which text color reads better on it. A live swatch and one-click presets are included. No library, no server, no upload - the conversion is plain integer math that runs on this page and is never uploaded. Honest limits: values assume standard sRGB, channels outside 0 to 255 are clamped (and the note says so), and screen calibration changes how any swatch looks.
- RGB channels are 0 to 255 in standard sRGB - the same web color space, not printer CMYK ink values.
- Hex is base-16: each pair of digits is one channel, 00 is 0 and FF is 255 - #RRGGBB, R for red, G for green, B for blue.
- The 3-digit shorthand (#RGB) only works when each channel is a doubled digit - #F0A expands to #FF00AA, but #6C5CE7 has no short form.
- HSL shown next to the hex is the same color as hue, saturation and lightness - useful for picking related shades.
- HSV is a third view of the same color - value is the brightest channel, close to how painters mix pure pigment.
- Relative luminance is the WCAG weighted blend - green counts most (about 71%) and blue least (about 7%), matching human vision.
- Contrast ratios compare this color to white or black text - WCAG AA needs 4.5:1 for normal-size text.
- Channels outside 0 to 255 are clamped and the notes panel reports it - the conversion never invents numbers.
- Copy uses the clipboard API; if the browser blocks it, the hex is shown large enough to select and copy by hand.
- The swatch is this exact sRGB value on an untagged screen - calibration and night modes change how it looks.
- Conversion is exact integer math on this page - nothing is uploaded, stored or sent anywhere.
