Random String Generator
Build random strings from chosen character sets.
Random String Generator is a browser-based text tool on TextToolsBase. Build random strings from chosen character sets. To use it, paste or type your text and view the result directly in your browser — no signup and nothing to install.
Random strings are useful for test data, sample tokens, and placeholders where a fixed length and character set matter.
Random String Generator lets you set the length, the number of strings, and the character set, then builds them all at once.
How to use Random String Generator
- Set the string length and how many strings you need.
- Choose a character set such as letters and numbers, letters only, or hex.
- Press Generate, then copy the strings, one per line.
Use cases
- Creating sample strings for testing a form or import.
- Generating placeholder values of a fixed length.
- Producing random identifiers for a mockup or demo.
Good to know
Random String Generator draws characters from the set you choose: alphanumeric, letters only, numbers only, hex, or letters, numbers, and symbols. You set the length and the number of strings, which appear one per line. Length and count are capped, including a total-size cap, so the page stays responsive. Strings are not a substitute for a secure password or token generator. Everything runs in your browser.
Frequently asked questions
Which character sets are available?
You can choose alphanumeric, letters only, numbers only, hexadecimal, or a set that adds symbols, depending on what your test data needs.
Can I generate several strings at once?
Yes. Set the count to produce multiple strings, each on its own line, all at the chosen length.
Are these safe to use as passwords?
No. These strings are for test data and placeholders; use a dedicated secure generator for real passwords or tokens.
Is the output capped?
Yes. Length, count, and total size are capped to keep your browser responsive, with a note when a cap applies.
