HSL to RGB Converter

Convert HSL values to RGB with a fixed input and output format, live preview of the conversion line, and copy-ready results. All processing runs locally in your browser.

Calculator

Input (HSL)

From: HSL (hue, saturation, lightness)

Result (RGB)

To: RGB (red, green, blue)

About HSL

HSL uses hue (0–360°), saturation (0–100%), and lightness (0–100%). It is convenient for adjusting perceived brightness and vividness.

About RGB

RGB expresses a color as three integers from 0 to 255 for red, green, and blue in the sRGB space. It matches how screens mix light.

How to convert HSL to RGB

Enter a valid HSL value in the calculator. The tool follows the pipeline below: parse your input, hold the color as sRGB (with alpha when relevant), then format the result as RGB.

Accepted shapes include CSS-like functions (e.g. rgb(...), hsl(...)) and compact comma-separated numbers where appropriate. Hex may include or omit the leading #.

Conversion procedure

Parse HSL: accept hsl(h, s%, l%) or three numbers; hue may omit the degree symbol and is wrapped to 0–360°. Saturation and lightness are read as 0–100 (percent signs optional). The parser does not output HSL again here—it only reads your numbers so the tool can move onward to sRGB.
Convert HSL → sRGB: saturation and lightness are scaled to 0–1. Chroma C = (1 − |2L − 1|) × S. A temporary RGB triple is built from hue’s 60° segment (the “hex cone” model), then the same offset m = L − C/2 is added to each channel. Finally, each channel is multiplied by 255 and rounded to the nearest integer with clamping to 0–255.
Build RGB: emit css rgb(r, g, b) with integer channels 0–255 separated by commas and spaces, matching common authoring style.
Finalize: the result string is what you copy from the calculator. The line under the fields summarizes the path in short form (RGB ← sRGB ← HSL). Rounding is intentional so values read like typical CSS; tiny differences versus other apps can still appear because of integer hue, saturation, lightness/value, or ink percentages.
HSL/HSV reminder: when hue, saturation, and lightness/value are shown as whole numbers, more than one underlying RGB can produce the same text. Typing those integers back into a converter may therefore differ by ±1 from a color you first picked as HEX in the Color Picker—that is expected rounding behavior, not a broken formula.

Example

Input (HSL): hsl(204, 70%, 53%)

Output (RGB): rgb(51, 152, 219)

Summary

This page converts HSL input into RGB output. The numbered “Conversion procedure” above is the full breakdown: validation and parsing, conversion to a single internal sRGB (+ alpha) sample, derivation of RGB coordinates from that sample, and final rounding to the strings you see in CSS-oriented tools. The same pipeline runs in your browser as you type.

Relationship context

HSL (hue, saturation, lightness) and RGB (red, green, blue) are different ways to describe the same sRGB color (except CMYK, which is an approximate ink model). Converting HSL → RGB does not change the underlying color within the limits of each notation; it only changes how numbers are written.

Example conversions

Sample HSL values and the matching RGB output using the same rules as the calculator.

HSL input	RGB output
hsl(0, 100%, 50%)	rgb(255, 0, 0)
hsl(120, 100%, 25%)	rgb(0, 128, 0)
hsl(204, 70%, 53%)	rgb(51, 152, 219)
