These tools process inputs and generate results in the browser; data is not uploaded by these tools.
The tools use the browser's Web Crypto random source, but they are general-purpose utilities, not substitutes for regulated draws, passwords, cryptographic keys, or security tokens.
Limits vary by tool. Large lists, batches, and custom character sets may be limited to keep the page responsive, so check the selected tool's limits first.
