Generate Random Unicode
Quickly generate random Unicode text in a given range. Runs entirely in your browser, so your data never leaves your device.

How to use Generate Random Unicode
- 1. Set How many characters to generate. Enter the number of random characters you want in the result. Higher counts are useful for stress-testing a text field or generating filler data.
- 2. Set the code point bounds. Enter From code point (hex) and To code point (hex) to restrict which block the random characters come from, for example 0021 to 007E for random printable ASCII.
- 3. Generate and copy. The tool picks that many random code points inside your range and joins them into one string. Copy the result or regenerate for a fresh set.
When to use Generate Random Unicode
Generate Random Unicode produces random characters restricted to a code point interval you set, rather than pulling from the entire Unicode table. Use it whenever you need noise data from a specific script or block.
- Fuzz-testing a text input field. A form validator needs to handle arbitrary Unicode gracefully. Generating random characters from a wide range and pasting them into the field checks for crashes or mangled rendering.
- Creating random passwords from a symbol set. A security exercise wants passwords drawn from a specific punctuation and symbol range rather than the standard alphabet. Setting the bounds to that block generates candidate strings.
- Simulating garbled or corrupted text for a demo. A bug report mockup needs text that looks corrupted or mojibake-like. Generating random characters from a high code point range produces a convincing garbled sample.
- Producing sample CJK or Cyrillic filler text. A layout test needs placeholder text in a non-Latin script to check how a font renders it. Restricting the range to that script's block generates believable filler.

About the Generate Random Unicode tool
Generate Random Unicode does its work locally, right in the browser. Quickly generate random Unicode text in a given range. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the Unicode Tools collection on EditSafely, a set of 98 small, focused Unicode utilities that share the same instant, private workspace.
You can shape the output with 3 settings, including How many, From code point (hex) and To code point (hex), and the result refreshes the moment you change one. A worked example further down the page shows exactly what the tool produces for a real input.
Running locally also makes the tool fast and dependable: results appear as you type or drop a file, there is no server outage that can take it down mid-task, and confidential data can be processed without a second thought.
Frequently asked questions
Does Generate Random Unicode cost anything?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Does the generator send anything to a server?
No data leaves your device. The whole tool is JavaScript that runs inside your browser tab, so there is no upload, no server-side processing and no log of what you did. If you disconnect from the internet after the page loads, it keeps working.
How do I get a different result?
Run the generator again. Each run is computed fresh on your device, and any options you change are applied to the next result immediately.
Do I need to sign up or install anything?
Nothing to install and no account needed. Open the page in any up-to-date browser, including on a phone or tablet, and the tool is ready.
How do I use the result?
The output panel has a one-click copy button, and you can keep refining the input while you work; the result updates in place as you type.
