Frequently Asked Questions
Four comma-separated numbers: red, green, blue (0-255), and alpha (0-1), e.g. "79, 70, 229, 0.5".
The result is an 8-digit hex code (#RRGGBBAA) — the first 6 digits are the usual RGB color, and the last 2 encode the alpha/opacity value as a hex byte.
Not universally — 8-digit hex with alpha is supported in modern CSS and by most current browsers, but some older software or contexts (like some raster image formats) don't recognize the alpha suffix and may only read the first 6 digits.
No — the conversion happens entirely in your browser.
