How to use Anonymize Text
- 1. Paste the text to anonymize. Paste names, identifiers or any sensitive words into the input pane, such as a list of people's names that need to be obscured before sharing.
- 2. Set how much of each word to keep. Enter a number in Keep first N characters of each word to control how many leading letters stay visible, and set Mask character for the symbol covering the rest.
- 3. Copy the anonymized text. Copy the result, where most of each word is masked but the shape and length are preserved, and paste it wherever you need to redact identity without deleting structure.
When to use Anonymize Text
Anonymize Text masks most of every word so the underlying text can't be read, while keeping a few leading characters and the original word shape visible. It's meant for redacting names and identifiers while still showing that something was there.
- Redacting names in a shared bug report. A support ticket includes customer names that shouldn't be visible to the wider engineering team, and anonymizing them keeps the report readable while hiding the identity.
- Preparing sample data for a demo. A product demo uses real customer records, and anonymizing the names first lets you show realistic-looking data without exposing anyone's actual identity on screen.
- Sanitizing a dataset before sharing with a vendor. You need to hand a dataset to an outside contractor for testing, and masking the names first keeps the row structure intact while hiding who the data belongs to.

About the Anonymize Text tool
Anonymize Text does its work locally, right in the browser. Mask most of every word so the text can't be read. There is no upload step, no queue and no account, and your data never travels over the network.
It belongs to the Text Tools collection on EditSafely, a set of 211 small, focused Text utilities that share the same instant, private workspace.
You can shape the output with 2 settings, including Keep first N characters of each word and Mask character, 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
Is Anonymize Text free to use?
Yes, it is completely free. All 2,658 tools on EditSafely work without an account, a subscription or usage limits.
Is it safe to paste sensitive or confidential data?
Everything happens locally. Your browser downloads the tool's code once, then does all the processing itself; nothing you enter is transmitted, stored or logged. You can even go offline after the page loads and it will still work.
How much text can I process at once?
There is no fixed limit. Because the work happens on your own device rather than on a shared server, the practical ceiling is your machine's memory, which comfortably handles inputs far larger than typical online tools allow.
Do I need to sign up or install anything?
No. The tool works in any modern browser on desktop, tablet or phone. There is no account to create, no extension to add and no software to install.
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.
