RGB Converter

Three conversion directions cover every pairing among RGB, hexadecimal, and HSV: RGB to Hex and HSV starts from red, green, and blue channel values and derives the hexadecimal code and hue, saturation, and value equivalents; Hex to RGB and HSV starts from a hexadecimal color code and derives its RGB channels and HSV breakdown; HSV to RGB and Hex starts from hue, saturation, and value and derives the RGB and hexadecimal representations.

RGB values are integers between 0 and 255 per channel; fractions, mixed numbers, and decimals are accepted and clamped to that range. A hexadecimal code is 3 or 6 characters, with an optional leading hash; a 3-character code such as F80 expands to FF8800. HSV values are a hue between 0 and 360 degrees, and saturation and value as percentages between 0 and 100.

RGB to Hex maps each channel (0 to 255) to a two-digit hexadecimal pair, concatenated as #RRGGBB. RGB to HSV normalizes the three channels to 0 to 1, computes hue from the delta and the dominant channel, saturation as delta divided by max, and value as the maximum channel. HSV to RGB divides the hue circle into six 60-degree sectors and interpolates channel values using intermediate variables derived from saturation, value, and the fractional hue position. Settings can show this derivation step by step for whichever conversion is running, including the normalization, delta computation, and sector interpolation.

Converting between RGB and Hex is exact in both directions, since a hex pair is only a different notation for the same 0 to 255 channel value. Converting to or from HSV can introduce small rounding differences, since hue, saturation, and value are computed from ratios of the RGB channels that do not always divide evenly back to whole integers, so a round trip through HSV can shift a channel value by one or two.

A preview swatch shows the resulting color for visual verification alongside the numeric output. Entered values and the selected conversion direction persist between sessions, so returning to the tool restores the previous state.

Color format conversion is a routine requirement across digital design, front-end development, and print production workflows. Different tools and specifications accept color in different notations, making quick bidirectional conversion between RGB, Hex, and HSV a frequent task.

• Web Development: Translate an HSV color picked from a design mockup into a hexadecimal code for CSS stylesheets, or verify that a hex code from a brand guide matches the expected RGB channel values before embedding it in HTML.
• Graphic Design: Match a color across applications that use different models. Enter RGB values from one program and retrieve the HSV equivalent for a tool that uses hue and saturation sliders, maintaining visual consistency without manual calculation.
• UI Prototyping: Adjust saturation and brightness in HSV to create tint and shade variations of a base color, then copy the resulting hex codes directly into prototype code or design tokens.
• Brand Identity: Document a brand palette in all three formats at once. Enter the primary brand color in hex and record the RGB and HSV equivalents for internal style guides, ensuring every team member references the same values regardless of the tool they use.
• Photography: Evaluate the hue, saturation, and brightness breakdown of a sampled pixel color by entering its RGB values and inspecting the HSV components before applying corrections.
• Game Development: Map HSV-based color pickers in a level editor to the RGB integers required by a rendering engine, or translate hex color constants into per-channel values for shader uniforms.
• Education: Explore how changes in one color model map to another by sliding the hue through 0 to 360 degrees and observing how red, green, and blue channels shift.
