Random Text Generator
Create random strings of letters, numbers, symbols, or a mix. Choose the length and character set, then copy or download the result. Perfect for testing, placeholders, passwords, and more. No signup, no uploads — everything runs right in your browser.
Why use this Random Text Generator?
Random strings are essential for developers testing software, designers needing placeholder content, or anyone who needs a quick, unpredictable sequence of characters. Our generator runs entirely in your browser, so the randomness is local and your generated text never leaves your device.
- Multiple character sets – choose from letters, numbers, symbols, or any combination.
- Adjustable length – generate anything from a single character to 10,000 characters.
- Instant generation – click the button or adjust options to get new text immediately.
- Privacy‑first – all generation happens locally; no data is sent anywhere.
How to generate random text (step‑by‑step)
1. Set the length
Enter how many characters you want in the length field.
2. Choose character set
Select which characters to include from the dropdown. Use "Mixed" for maximum randomness.
3. Generate
Click the "Generate" button (or just change options) to fill the text area with random characters.
4. Copy or download
Use the buttons to copy the random text to your clipboard or save it as a .txt file.
Example output
Here's what a 100‑character mixed string might look like:
aG7$kL9@pX2!mN5&qW8^rT4*vY1#zC3~bJ6%dH0(fU8_sM2)lK7?wE9+oP3|xA4]cD5{gF1:hR6}iQ0=vB8"jZ5;yN2'tG4,mU8-uJ3&lO7!pI9@wC6#eS0*rK2~xM5^dH1(vT8_aF4)bN7?qX2]lZ6;cG3{jP0:iY5}dW1=hR8"oM4;tB9,uF2-sK7&wJ3!eL0@pC6#vS1~xN5^gH8_aI4)rT7?qD2]bY6;mZ3{cF0:jP5}lW1=iR8"oX4;tG9,uM2-sB7&kJ3!eH0@pL6#vN1~xC5^gS8_aF4)rI7?qT2]bD6;mY3{cZ0:jW5}lP1=iR8"oX4;tG9,uM2-sB7&kJ3!eH0@pL6#vN1~xC5^gS8_aF4)rI7?qT2]bD6;mY3{cZ0:jW5}lP1=
With "Letters only" you would get something like: MxQwErTyUiOpAsDfGhJkLzXcVbNmVqWeRtYuIoPaSdFgHjKlZxCvBnMqWeRtY
Common use cases
- Software testing: Fill forms or database fields with random strings to validate input handling.
- Password generation: Create strong, random passwords (for dedicated password generation, try our Password Generator).
- Placeholder content: Use random text instead of Lorem Ipsum in mockups.
- Gaming: Generate random codes, names, or identifiers.
- Encryption keys: Produce random strings for salts or initialization vectors.
Pro tips
- For strong, secure passwords, select "Mixed" and a length of at least 16 characters.
- The "Symbols only" set includes characters like
!@#$%^&*()_+-=[]{}|;':",./<>?— great for stress‑testing input fields. - If you need random words instead of random characters, try our Random Word Generator.
- The generator uses
Math.random(), which is sufficient for most non‑cryptographic purposes. For cryptographic randomness, consider a dedicated library.
