Generate v4 UUIDs securely with the Web Crypto API.
Was this tool useful?
Are UUIDs generated securely?
Yes. The tool uses `crypto.randomUUID()` when available. If not, it falls back to a safe RFC4122-style generator.
Does this tool upload or log the generated UUIDs?
No. All UUIDs are generated locally and never sent to any server.
How many UUIDs can I generate at once?
You can generate between 1 and 1000 UUIDs in a single batch.
Can I customize the output?
Yes. You can choose lowercase/uppercase, with or without hyphens, and add optional prefixes or suffixes.
Can I download all UUIDs?
Yes. You can copy them to clipboard or download a `.txt` file containing all generated UUIDs.
Why does the tool have a delimiter setting?
The delimiter controls how the UUIDs are joined (e.g., newline, comma, space) when output is copied or downloaded.
Can I rely on these UUIDs for security-sensitive applications?
No. Although generated securely, this tool is not intended for cryptographic or high-security uses.
