Random Number Generator — Integers in a Range | Yaya Tools
Generate random numbers by range and count
Tool guide
Set min, max, and count, then generate. Enable Unique to avoid duplicate numbers.
- Maximum count is 1000
- With Unique enabled, count cannot exceed the available range
- Results are generated locally in your browser
Standards and limits
The ECMAScript specification for Math.random() explicitly permits an implementation-dependent pseudorandom algorithm. This page therefore labels its output as unsuitable for passwords, tokens, lotteries, regulated drawings, or security decisions. Applications needing cryptographically strong browser randomness should use the W3C-defined crypto.getRandomValues() API instead.
FAQ
Is this cryptographically secure random?
No. It uses Math.random — fine for test data, not for security-sensitive use.
Does my data leave the browser?
No, random numbers are generated locally in your browser.
