How to use HEX to RGBA Converter

Enter a hex color, drag the opacity slider to set alpha, preview the transparency, and copy the rgba() string.

Frequently asked questions

How do I turn hex into rgba?

Split the hex into red, green and blue pairs, convert each to 0–255, then add your chosen alpha value to form rgba().

What alpha value should I use?

Alpha ranges from 0 (invisible) to 1 (solid). 0.5 is half-transparent; pick the value that matches your design.

Does it accept shorthand hex?

Yes — 3-digit shorthand like #f00 is expanded to #ff0000 before the rgba() value is produced.
