How to use Justify Text
- 1. Paste the lines you want justified. Enter a paragraph or list of lines you want stretched to a uniform width, such as a caption block or a paragraph you're formatting for a monospace layout.
- 2. Set the Width. Enter the target line width, or leave it at 0 to justify against the longest line already present in your input.
- 3. Review the stretched output. Spaces between words are widened so every line reaches exactly the target width, with both the left and right edges flush, matching how printed newspaper columns look.
- 4. Copy the justified text. Copy the result into a plain-text document, a fixed-width layout, or anywhere a fully justified block of text is needed.
When to use Justify Text
Justify Text stretches the spaces between words so every line reaches the same width on both sides, the classic full-justification look from printed books and newspapers. Use it in plain-text or monospace contexts where CSS text-align justify isn't an option.
- Formatting a caption block to match a print layout. A print mockup needs a caption's lines flush on both edges to match the surrounding column of body text. Justifying the caption to the same width keeps the whole layout consistent.
- Recreating a newspaper-style column in plain text. A retro design or ASCII art project wants text that reads like a justified newspaper column. Stretching the spacing to a fixed width produces that flush-both-sides look without a layout engine.
- Aligning a short quote inside a fixed-width terminal box. A terminal UI draws a box of a known character width around a quote, and the text inside needs to fill the box edge to edge on each line for a clean fit.
- Preparing body text for a monospace font display. A signage or e-ink display renders only a monospace font and you want paragraphs to look evenly filled rather than ragged on the right edge.

About the Justify Text tool
Justify Text is a free online tool that works entirely inside your web browser. Stretch spaces between words so all lines are equal length. Because the processing happens on your own device, nothing you enter is uploaded, logged or stored anywhere.
This page is one of 211 Text 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 the Width (0 = longest line) setting, and the result refreshes the moment you change it. 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 Justify 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.
