What Is a Hex to RGB Converter?
A hex to RGB converter translates hexadecimal color codes (like #FF5733) into their RGB (Red, Green, Blue) decimal equivalents. This conversion is essential for web development, as CSS supports both hex and rgb() color formats.
How to Use This Hex to RGB Converter
- Enter one or more color values in the input area (one per line). The tool accepts both hex codes (e.g.,
#FF5733orFF5733) and RGB values (e.g.,rgb(255, 87, 51)or255, 87, 51). - Click Convert to convert. Hex inputs are converted to RGB, and RGB inputs are converted to hex—the conversion is bidirectional.
- Use the Copy button to copy the results.
Key Concepts
Hex colors use 6 hexadecimal digits: the first two represent red (00-FF), the middle two green, and the last two blue. Each pair converts from base-16 to a decimal value between 0-255. For example, #FF5733 breaks down to R=255, G=87, B=51. Shorthand hex (#F00) expands by doubling each digit (#FF0000).
Frequently Asked Questions
What about 8-digit hex codes?
8-digit hex codes include an alpha channel for transparency. The last two digits represent opacity from 00 (fully transparent) to FF (fully opaque), converting to RGBA values.
Is there a formula for the conversion?
Yes. Each hex pair converts independently: R = parseInt(hex[0..1], 16), G = parseInt(hex[2..3], 16), B = parseInt(hex[4..5], 16). Each result ranges from 0 to 255.
Which format should I use in CSS?
Both are equally valid in CSS. Hex is more compact (#FF5733), while rgb(255, 87, 51) is more readable. Use rgba() when you need transparency.
