Random Binary Generator
Choose a bit length and number of strings, then generate binary values in your browser without sending input anywhere.
A QUICK WALKTHROUGH
How to use this tool
- Choose a bit length from 1 to 1024.
- Choose between 1 and 100 binary strings.
- Generate the values, then copy the newline-separated result.
Bounded output
Each result contains exactly 1 to 1024 bits, and each request returns 1 to 100 lines. Leading zeroes are preserved so every line has the selected length.
Local browser randomness
The generator uses crypto.getRandomValues when available and never uploads or stores the result. Browser randomness is suitable for general-purpose sampling, but this page is not a reviewed secret-key, token, or security-critical generator.
GOOD TO KNOW
Common questions
How many bits can I generate?
Each binary string can contain from 1 to 1024 bits.
Can I generate several strings at once?
Yes. Choose from 1 to 100 strings per request.
Are leading zeroes kept?
Yes. Every result is padded to the selected bit length.
Is this suitable for cryptographic keys?
No. It uses browser cryptography for local random sampling, but it is a general-purpose utility without key handling, security review, or guarantees for security-critical use.
