Bulk UUID Generator

Privacy-first • No tracking • Client-side

About Bulk UUID Exporter

The Bulk UUID Exporter is a free, open-source, 100% client-side web utility that instantly generates up to 10,000 standards-compliant version-4 UUIDs and exports them as clean CSV or JSON — all without ever leaving your browser.

Built for **developers**, database administrators, QA engineers, and anyone who regularly needs realistic unique identifiers, this tool removes every unnecessary barrier. No accounts. No installations. No rate limits. No data collection. Just open the page, type a number, and download perfect UUIDs in under five seconds.

Every UUID is created using the browser’s native `crypto.randomUUID()` function, which taps directly into your operating system’s **cryptographically secure random number generator**. This ensures Version-4 UUIDs with 122 bits of entropy and a collision probability so low it is considered impossible in practice.

Privacy is the core architecture. Because the entire application is static and runs exclusively in your browser, **nothing is ever transmitted to a server**. Your generated identifiers never touch the network. There are no analytics, no tracking pixels, and no server logs.

Whether you’re offline on a plane, working in a secure environment where external API calls are blocked, or simply value absolute data sovereignty, Bulk UUID Exporter works exactly the same: instantly, privately, and reliably.

Frequently Asked Questions

Yes. They are version-4 UUIDs generated using crypto.randomUUID(), which sources 122 bits of cryptographically secure randomness directly from your operating system. The collision probability is approximately 1 in $2^122$ — far lower than winning the lottery multiple times in a row. Major databases and cloud providers consider v4 UUIDs safe as primary keys without additional checks.

The limit guarantees smooth performance and prevents accidental browser freezes on lower-end devices. Ten thousand UUIDs cover 99.9% of daily development and testing needs while keeping memory usage low. Need more? Simply run multiple batches — the tool has no rate limiting.

Absolutely private. The application is **100% client-side**. No network requests are made after the initial page loads (except for the Bootstrap CDN). Your UUIDs exist only in browser memory and are discarded when you close the tab. Even if someone intercepted your traffic, they would see nothing because nothing is sent.

Yes! Save the page as a complete HTML file or host it internally. After the first load, everything works offline forever without internet because only static assets are required. Perfect for secure environments and offline workflows.

Absolutely. The project is **MIT-licensed open source**. Fork it, customize it, rebrand it, host it on your intranet or GitHub Pages — no restrictions and no attribution required.
