Random Text Generator
Random Text Generator builds random strings of any length from the character sets you choose — lowercase, uppercase, digits, symbols and spaces — plus any custom characters you add. It's handy for test data, sample input, placeholder identifiers and quick filler.
Generate one string or many lines at once, optionally excluding look-alike characters. It runs entirely in your browser using a cryptographically secure random source, so generated text stays on your device.
How to use Random Text Generator
- 1
Set length and lines
Enter how many characters per line (up to 10,000) and how many lines to generate.
- 2
Choose character sets
Toggle lowercase, uppercase, digits, symbols and spaces, add your own custom characters, and optionally exclude similar-looking ones.
- 3
Generate and copy
Click Generate, then copy or download the random text.
What it's good for
Random text is useful for stress-testing forms and layouts, generating sample database records, creating throwaway test values, and filling fields where the content doesn't matter. Including spaces produces text that wraps like real prose, which is great for checking how a UI handles word breaks.
If you need readable, prose-like filler for a design mockup, use the Lorem Ipsum Generator instead.
Custom characters and look-alikes
Beyond the built-in sets you can paste your own characters into the custom field — arrows, accented letters, or any Unicode you like — and they're folded into the pool. Duplicate characters are removed so every character has an equal chance of appearing.
Turn on “Exclude similar” to drop easily confused characters (i, l, 1, L, o, 0, O), which is useful when the output will be read aloud, copied by hand or printed.
Randomness and passwords
The generator draws from the Web Crypto API (crypto.getRandomValues), a cryptographically secure source, so the output is suitable for tokens and test secrets. For full password management — strength meters, passphrases and storage — a dedicated Password Generator is still the better fit.
Frequently asked questions
- How long can the text be?
- You can generate up to 10,000 characters per line, across as many as 1,000 lines at once.
- Can I include symbols, spaces and custom characters?
- Yes. Toggle any combination of lowercase, uppercase, digits, symbols and spaces, and add your own characters in the custom field.
- Is the randomness secure?
- Yes. It uses the browser's cryptographically secure random source (crypto.getRandomValues). For managing real passwords, a dedicated password generator is still recommended.
