Question 1

Which UUID version is generated?

Accepted Answer

Version 4 (random). Values come from crypto.randomUUID when available, with a secure fallback — never from Math.random alone for the primary path.

Question 2

What formats can I export?

Accepted Answer

Lowercase, UPPERCASE, braces {GUID}, no hyphens, or URN (urn:uuid:…). Export as one-per-line, comma list, or JSON array.

Question 3

Are UUIDs uploaded?

Accepted Answer

No. Generation and validation run entirely in your browser.

Question 4

What is an HTML color code?

Accepted Answer

An HTML color code is a way to specify colors in web pages using HEX (#RRGGBB), RGB, HSL, or named CSS colors. HEX is the most common format in CSS and HTML.

Question 5

How do I convert HEX to RGB?

Accepted Answer

Use our HEX to RGB converter. Paste a HEX value like #FF5733 and get rgb(255, 87, 51). You can also convert RGB back to HEX with the RGB to HEX tool.
