How to Use RGBA to HEX Converter

About this tool

Convert RGBA channels to HEX with alpha, without alpha or flattened over a background.

How to use RGBA to HEX Converter

1. Enter RGBA value or adjust Red, Green, Blue and Alpha.
2. Choose Background for flattening.
3. Copy the correct labeled output for your use case.

Worked example

Flatten a half-transparent red over white to obtain an opaque color approximating its appearance on that surface.

Why are HEX without alpha and Flattened HEX different?

Without alpha drops transparency; flattening combines the foreground with the selected background.

Will flattened HEX look the same on another background?

It remains opaque and will not blend with a new surface. Use alpha HEX when you need transparency.
