Generate Random Prime Numbers
A fast, privacy-first online tool to generate random prime numbers directly in your browser. All computation happens locally on your device - no servers, no tracking, no data collection.
Prime Number Generator
Upper limit for prime generation (recommended ≤ 1,000,000).
About This Tool
This random prime number generator uses well-established mathematical algorithms to compute prime numbers efficiently on your local device. Once generated, primes are randomly selected without repetition to ensure unbiased results.

Fun Fact
The largest known prime numbers often have millions of digits and are discovered using distributed computing projects rather than traditional computers.
Historical Context
Prime numbers have been studied for over two thousand years, dating back to ancient Greek mathematicians like Euclid. Today, primes remain foundational to modern computing, particularly in encryption and secure communication.
