Free UUID Generator No Sign Up — Tired of the 500 Cap?
Most free UUID generators cap bulk output at 500, or even 100, and only let you download a .txt file. ToolFlexy's free UUID generator has no sign up, no watermark, generates up to 5,000 UUIDs at once, and exports as TXT, CSV, JSON, or PDF.
Format Your Code in 4 Simple Steps
Get a clean, usable result in just a few clicks — fast, easy, and completely free.
Choose a UUID Version
Select v1, v4, or v7 depending on your use case. v4 is the default and most widely used for general-purpose unique IDs.
Pick an Output Format
Switch between Canonical, Uppercase, No Dashes, Braced, URN, Base64, or Quoted instantly. No need to regenerate your UUIDs to see a different style.
Generate One or Thousands
Click Generate for a single UUID, or switch to bulk mode for up to 5,000 at once. That's 5x uuidgenerator.net's cap and 50x uuidtools.com's cap.
Copy or Download
Copy a single UUID with one click, or download your full batch as TXT, CSV, JSON, or PDF. Most competitors only offer plain .txt downloads.

Frequently Asked Questions
Find answers to the most common questions about this tool.
Yes. Every feature on this page, including bulk generation up to 5,000 UUIDs and all 4 download formats, works with no account, no email, and no payment required.
v1 is timestamp-based and includes machine-derived data, v4 is fully random and the most common choice for general use, and v7 is a newer sortable format that embeds a timestamp prefix, making it ideal for database primary keys.
Up to 5,000 in a single bulk batch, compared to the 500-ID limit on uuidgenerator.net and the 100-ID limit on uuidtools.com.
TXT, CSV, JSON, and PDF. Most competing tools only offer a plain .txt export.
No. UUID generation happens entirely in your browser using client-side JavaScript, so nothing you generate is ever transmitted or stored on our servers.
Yes. Press C to copy the currently displayed UUID or R to regenerate a new one, using the built-in keyboard shortcuts.
Some systems and APIs expect UUIDs in a specific format — for example, Windows registry entries often use the Braced format, while URN format is used in some XML and RDF contexts.
Functionally, yes. GUID (Globally Unique Identifier) is Microsoft's term for the same concept defined by the UUID standard (RFC 4122).
Yes. UUID v4 and v7 are both commonly used as production primary keys. v7 is increasingly preferred for new systems since its sortable structure improves database index performance.
Yes. The generator is fully responsive and works the same way, single or bulk generation, all 7 formats, all 4 download types, on mobile browsers as it does on desktop.
