FAQ
What does padding mean?
With width 4, number 1 outputs as 0001 so every code has equal length for sorting; set 0 to disable.
What is the maximum count?
Up to 100k per run; generate in batches beyond that. Results can be copied or downloaded as TXT.
Will my data be uploaded?
No, all generation runs locally in your browser.
