About UUID Generator
UUID Generator is a free Becoderr tool. It needs no sign-up, runs fast and privately, and works right in your browser for most tasks. For the few server-based tools, your files are processed in memory and discarded immediately after the operation.
Frequently asked questions
What kind of UUID is generated?
Random RFC-4122 version-4 UUIDs, generated with your browser's cryptographically secure random number generator.
Are the UUIDs unique?
Version-4 UUIDs have 122 random bits, so the chance of a collision is astronomically small.
Is this tool free to use?
Yes. Every tool on Becoderr is completely free with no sign-up required. Signed-in users get higher file-size limits.
Are my files safe?
Yes. Browser-based tools process files entirely on your device; nothing is uploaded. Server-based tools process files in memory and discard them immediately after the operation.
Is there a file size limit?
Server-based tools accept up to 5 MB for anonymous users and 50 MB when signed in. Browser-based tools are limited only by your device.
