How do I convert HEX to RGB?

Enter a HEX color code (e.g., #3498db) in the HEX input field, and the RGB values update instantly. Each pair of hex digits represents one channel: RR for red, GG for green, BB for blue. The tool converts them automatically.

What is the difference between RGB and HSL?

RGB (Red, Green, Blue) defines colors by mixing light channels from 0-255. HSL (Hue, Saturation, Lightness) defines colors by hue angle (0-360 degrees), saturation (0-100%), and lightness (0-100%). HSL is often more intuitive for designers because adjusting lightness or saturation is straightforward.

Can I copy color codes to my clipboard?

Yes. Each color format (HEX, RGB, HSL) has a copy button that copies the formatted color code to your clipboard with one click, ready to paste into CSS, design tools, or any application.

Is the Color Picker free?

Yes, 100% free with no signup or ads. The tool runs entirely in your browser — no data is sent to any server.

What Is a Color Picker?

A color picker is a tool that lets you select a specific color and obtain its representation in different color formats used in web development, graphic design, and digital art. The three most common formats are HEX (hexadecimal), RGB (Red, Green, Blue), and HSL (Hue, Saturation, Lightness). Each format describes the same color differently, and converting between them is essential for working across different design tools and codebases.

HEX codes like #3498db are the standard in CSS and web design. RGB values like rgb(52, 152, 219) are used in CSS, JavaScript canvas operations, and most programming languages. HSL values like hsl(204, 70%, 53%) are increasingly popular because they map more intuitively to how humans think about color: you can easily make a color lighter by increasing the L value, or more muted by decreasing S, without affecting the base hue.

TweakFiles Color Picker runs entirely in your browser with no external dependencies. All conversions use pure mathematical formulas, so results are precise and instant. The bidirectional sync means you can edit any format and all others update in real time. Copy buttons let you quickly grab the exact code you need for your CSS, Figma project, or any design tool.

How to Use the Color Picker in 3 Steps

Pick or Enter a Color

Use the native color picker to visually select any color, or type a HEX code, RGB values, or HSL values directly into the input fields. All formats are bidirectionally synced, so changing any one updates all the others instantly.

See All Formats

The preview swatch shows your selected color at a glance. Below it, you see the color expressed in HEX, RGB, and HSL. Fine-tune individual values (like adjusting just the hue or lightness) to get exactly the shade you want.

Copy and Use

Click the "Copy" button next to any format to copy the color code to your clipboard. Paste it directly into your CSS stylesheet, design tool, or code editor. The copied format is ready to use without any modifications.

Frequently Asked Questions

Enter a HEX color code (e.g., #3498db) in the HEX input field. The RGB values update instantly. Each pair of hex digits maps to one color channel: the first two are Red (0-255), the next two are Green, and the last two are Blue. The formula is: R = parseInt(hex[1..2], 16), G = parseInt(hex[3..4], 16), B = parseInt(hex[5..6], 16).

RGB (Red, Green, Blue) defines colors by mixing three light channels, each ranging from 0 to 255. HSL (Hue, Saturation, Lightness) uses a more human-intuitive model: Hue is the color angle on a 360-degree wheel (0 = red, 120 = green, 240 = blue), Saturation controls vividness (0% = gray, 100% = full color), and Lightness controls brightness (0% = black, 50% = pure color, 100% = white). HSL makes it easier to create color variations by adjusting just one parameter.

Yes. You can paste a HEX code directly into the HEX input field, or enter RGB or HSL values into their respective fields. All other formats update automatically. This makes it easy to convert between formats when moving colors between tools like Figma, Photoshop, VS Code, or CSS files.

Yes. The conversions use standard mathematical formulas (the same ones specified in CSS Color Module Level 4). RGB-to-HSL and HSL-to-RGB conversions are precise. The only rounding happens when converting floating-point results to integer RGB (0-255) or HSL degree/percentage values, which is standard practice.

Absolutely. All color calculations happen entirely in your browser using JavaScript math. No color data, usage information, or personal data is ever sent to any server. Your color choices stay completely on your device.
