Convert RGB Colors to HEX

Translate RGB(255,255,255) to precise Hexadecimal (#FFFFFF) color formats online. Copy directly into your CSS files.

In image editing software like Photoshop or drawing applications like Procreate, colors are typically selected and output in RGB (Red, Green, Blue) format. However, when placing these colors into a website's stylesheet, HTML and CSS vastly prefer the compact nature of HEX codes. Our RGB to HEX converter bridges the gap between traditional graphic design and web development. You simply input the 0-255 values for Red, Green, and Blue, and our tool generates the exact 6-character `#` code required for your code.

We also support Alpha values (RGBA to 8-digit HEX), which is increasingly supported in modern browsers, allowing you to pass transparent values without breaking the HEX formatting conventions of your codebase.

Frequently Asked Questions

Wait, can a HEX code be 8 characters long?
Yes. In modern CSS, an 8-digit HEX code (like #FFFFFFFF) is valid. The final two digits represent the alpha (opacity) channel, ranging from 00 (fully transparent) to FF (fully opaque).
