Free Random Generators - Numbers, Passwords, UUIDs, Dates and More

Free online random generators for UUIDs, strong passwords, numbers, letters, dates, choices, and IP addresses. All generated locally in your browser — nothing stored or sent to servers.

Free random generators for UUIDs, passwords, numbers, letters, dates, choices, IP addresses, and more. Every result is generated locally in your browser using your device's built-in random functions. Nothing you generate is sent to or stored on our servers.

All Random Generators

UUID Generator
Generate universally unique identifiers (UUID v4) for databases, APIs, and software development. Generate one or many at a time.
Strong Password Generator
Create high-entropy passwords with custom length, uppercase, lowercase, numbers, and symbols. Uses cryptographic randomness for maximum security.
Random Number Generator
Generate random integers or decimal numbers between any two values. Set your own minimum and maximum and generate as many as you need.
Random Letter Generator
Generate random letters from the English alphabet. Choose uppercase, lowercase, or mixed, and specify how many to generate.
Random Date Generator
Generate random dates within a date range you specify. Useful for test data, sample datasets, and generating realistic placeholder content.
Random Month Generator
Generate one or more random months from the calendar year. Useful for test datasets, random sampling, and content generation.
Random Choice Generator
Enter a list of options and let the tool pick one at random. Useful for making decisions, picking names, choosing from a list, or running raffles.
Random IP Address Generator
Generate random IPv4 or IPv6 addresses. Useful for developers, testers, and anyone who needs realistic placeholder network addresses.

When to use random generators

  • Software testing: Fill databases and test forms with realistic random data — dates, IDs, addresses, names.
  • Security: Generate strong passwords and unique identifiers for accounts, tokens, and API keys.
  • Decision making: Use the random choice generator when you genuinely cannot decide between options.
  • Education: Create random datasets and examples for statistics, probability exercises, and data analysis.

Are the generated values truly random?

All our random generators use your browser's built-in cryptographic random number generator (crypto.getRandomValues) where security matters — for example, in the password generator. For general-purpose tools like random number or random date generators, we use JavaScript's Math.random(), which is suitable for most everyday tasks.

Is my generated data stored anywhere?

No. Everything is generated locally in your browser and never sent to our servers. Close or refresh the page and the generated values are gone.

Can I generate multiple values at once?

Yes. Most of our random generators let you specify how many results to generate in one go, so you can produce lists of UUIDs, passwords, numbers, or other values without repeated clicks.

Are the generated passwords safe to use?

Our strong password generator produces high-entropy passwords using cryptographic randomness and lets you customise length, character sets, and exclusions. That said, always use a reputable password manager to store any passwords you generate.
