How to use Wrap a String
- 1. Paste the string. Enter a long line or paragraph of text into the input pane. Wrap a String reflows it into multiple lines that each fit within a maximum width.
- 2. Set the Line width. Enter the maximum number of characters allowed per line in Line width, matching the column limit of your terminal, code editor, or document format.
- 3. Turn on hard-breaking long words. Turn on Hard-break words longer than the width to force a single long word, like a URL, to split across lines rather than letting it exceed the line width.
- 4. Copy the wrapped text. Copy the reflowed paragraph out of the output pane, now broken into lines no wider than your specified limit, ready to paste into its destination.
When to use Wrap a String
Wrap a String reflows a long line or paragraph into multiple lines that respect a maximum width, breaking at word boundaries by default. Use it whenever text needs to fit a fixed-width display like a terminal, code comment, or plain-text email.
- Formatting a paragraph for a code comment. You are writing a long explanatory comment in source code and want each line capped at 80 characters to match the project's style guide before pasting it in.
- Preparing plain-text email body copy. An email client or mailing list expects plain-text messages wrapped at a conventional width like 72 characters so it displays correctly across different mail readers.
- Reflowing text for a terminal-width display. You are outputting a message in a command-line tool and want it wrapped to a fixed column width so it reads cleanly regardless of the user's terminal size.
- Handling a long URL inside wrapped text. A paragraph contains a URL longer than your wrap width, and turning on hard-breaking prevents that one word from stretching the line past the limit you set.

About the Wrap a String tool
Wrap a String is a free online tool that works entirely inside your web browser. Wrap a string to a maximum line length. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 159 String utilities on EditSafely. Each one does a single job well, and all of them follow the same rule: your input stays on your machine.
You can shape the output with 2 settings, including Line width and Hard-break words longer than the width, 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.
Because nothing leaves your device, the tool is suitable for sensitive content such as internal documents, credentials or customer data. It also responds instantly, since every keystroke is handled on your own machine rather than by a remote API.
Frequently asked questions
Is Wrap a String 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.
