Random Generator
Pick a type and generate random values — strings, passwords, numbers, hex, colors, Base64, byte arrays, or UUIDs — using your browser's secure randomness.
Random values
Secure · localAbout Random Generator
The Random Generator produces random values of several types — strings, passwords, numbers, hex, colours, Base64, or byte arrays — from one tool. It is for developers who want a single place for varied random output.
Rather than hunting for a separate tool per type, this covers the common ones. Generating locally from a secure source keeps values private.
Step by step
- Pick the type of value to generate.
- Set any options for that type, such as length or range.
- Generate the value.
- Generate again for more.
- Copy the result — Random.
What it offers
- Strings, passwords, numbers, hex, colours, Base64, and bytes
- Per-type options
- Secure random source — Random
- Runs locally — Random
Where it helps
- Generating different random values from one tool
- Producing test data of varied types
- Creating a quick random colour or number
- Grabbing a random string or byte array on demand
Tips for best results
- Store any generated secret in a password manager rather than reusing it.
- Pick a length or range that gives enough unpredictability for the purpose.
- Use a certified system for regulated or high-stakes draws.
Pitfalls to watch for
- Using a generated password without storing it in a manager.
- Choosing too short a length for values that need unpredictability.
- Relying on it for regulated draws that require certified systems.
