HEX to RGBA Converter

Scan to open this page

Convert between HEX, RGB, RGBA, and HSL instantly — edit any format and the other three update live, with a built-in picker and alpha slider.

How it works

  1. Pick a color, or type directly into the HEX, RGB, RGBA, or HSL field
  2. The other three formats update instantly — no button, no separate page per direction
  3. Drag the alpha slider to adjust transparency; it's reflected in the 8-digit HEX and RGBA output

Frequently asked questions

What does the A in RGBA mean?

Alpha (transparency) — a value from 0 (fully transparent) to 1 (fully opaque).

Does it support 8-digit HEX (#RRGGBBAA)?

Yes — when alpha is below 100%, the HEX field automatically shows the 8-digit form with the alpha channel included.

When is HSL more useful than RGB?

HSL separates hue, saturation, and lightness, which makes it easier to adjust one property (like making a color lighter) without changing its hue — common in design systems.

Can I pick a color visually instead of typing a code?

Yes — the color picker is built into the converter itself, not a separate tool, and updates all four formats the moment you pick.

RGB to Hex and Hex to RGB are different pages on the tool most people use. Ours is one.

A popular color converter splits RGB-to-Hex and Hex-to-RGB across separate URLs, has no alpha/transparency support, and keeps its color picker on a different page entirely. Ours does all of it, live, in one place.
