Random Number Generator
Use our free Random Number Generator to create random numbers for games, passwords, or statistical sampling. Customize range, quantity, and duplicates for your needs.
Generate Truly Random Numbers
Need random numbers for a lottery draw, classroom exercise, game, password, or statistical sample? This generator uses cryptographically secure randomness (PHP's random_int) on the server — far more random than browser-based Math.random().
Generate up to 1,000 numbers at once, with or without duplicates, in any integer range. Optionally sort the results for easy reading.

FAQ – Random Number Generator
What is a Random Number Generator?
A Random Number Generator (RNG) produces numbers with no predictable pattern within a specified range. This tool uses cryptographically secure randomness (PHP random_int) for high-quality results.
Are the generated numbers truly random?
Yes. This tool uses PHP's random_int() function, which draws from the operating system's cryptographic random number generator (CSPRNG). This is significantly more random than browser-based Math.random().
Can I generate numbers without duplicates?
Yes. Uncheck "Allow Duplicates" to generate unique numbers only. The quantity cannot exceed the range size when duplicates are disabled (e.g., you can't pick 10 unique numbers from 1–5).
What is the maximum quantity I can generate?
You can generate up to 1,000 numbers at once. For unique numbers, the quantity is limited by the range size.
Can I use this for lottery numbers?
Yes. Use the "Lottery 6/49" preset or set your range and quantity manually with duplicates disabled. The numbers are generated with cryptographic randomness for fairness.
What are the quick presets?
Presets auto-fill common scenarios: single die roll (1–6), lottery picks (6/49), coin flips (0–1), 4-digit PIN (1000–9999), and more. Click any preset then generate.
Can I sort the generated numbers?
Yes. Check "Sort Results" before generating to receive numbers in ascending order. This is useful for lottery picks or when you need ordered results.
Is my data stored or tracked?
No. Numbers are generated on the server and returned to your browser. Nothing is stored, logged, or tracked. Each generation is completely independent.
What's the difference between CSPRNG and PRNG?
CSPRNG (Cryptographically Secure PRNG) uses OS entropy for unpredictable results suitable for security. Regular PRNG uses mathematical algorithms that are faster but potentially predictable. This tool uses CSPRNG.
Can I use this for statistical sampling?
Yes. Generate unique random numbers within your population range to select random samples. The cryptographic randomness ensures unbiased selection for research and surveys.
