Frequently Asked Questions

How does UUID Generator work?

UUID v4 values use cryptographically secure browser randomness. Generate up to 1,000 values per batch.

Does this tool upload or save my input?

Core processing happens locally in this browser tab. Input and output are not sent to a processing server or stored automatically. Copy and download only occur when you request them.

What happens with large or invalid inputs?

Input limits and errors are shown in the workspace. JSON supports up to 1 MB and 100 nesting levels; large previews can be truncated while downloads retain the full result.
