Bulk version-4 UUIDs from your browser’s cryptographic random source — formatted your way, never sent anywhere.
Version 4 (random) UUIDs from your browser’s crypto generator — never sent anywhere.
0 UUIDs
Runs in your browser. Files are never uploaded — you can go offline after the page loads.
How to use the UUID Generator
Set how many you need.
Toggle uppercase, hyphens or braces.
Copy all or download as a text file.
Easy to use
Drop files, pick options, download. Whole folders at once, no signup, no daily limit.
Best quality
The same engines the professionals use — SVGO, resvg, MozJPEG, libwebp, libavif — compiled to run in your browser.
Private & secure
Files are processed on your device and never uploaded. Close the tab and nothing remains anywhere.
Random v4 UUIDs, in bulk
Generate anywhere from one to a thousand version-4 UUIDs at once, formatted the way your system needs — uppercase,
with or without hyphens, wrapped in braces. They come from the browser’s cryptographic random source
(crypto.randomUUID), the same generator used for secure tokens, so collisions are astronomically unlikely.
Nothing is transmitted or logged — the IDs exist only in your browser until you copy or download them. For file
checksums see File Hash; for hashing text, the Hash Generator.
Frequently asked questions
Are these safe to use as IDs?
Yes — they’re version-4 UUIDs from crypto.randomUUID / getRandomValues, the same source used for secure tokens, so collisions are astronomically unlikely.
Do they ever repeat or get logged?
They’re generated locally in your browser and never transmitted or stored, so nothing sees them but you.
Most online converters upload your file to a server. InfyTool ships the actual encoders to your browser as WebAssembly instead, so processing happens inside your tab — faster for batches, and nothing to delete afterwards.
No upload, ever. Turn off Wi-Fi after the page loads and every tool keeps working.
No limits. No file-size cap, no queue, no watermark, no account.
Runs on your CPU. Batches use several cores in parallel; nothing is throttled.
