Wrap Text – Free Online Line Wrapper (10–500 Characters)

What is the Wrap Text tool?

The Wrap Text tool is a free online utility that reformats long lines of text so that each line stays under a maximum number of characters you choose. It's the digital equivalent of the "word wrap" feature in a word processor — but here you control the exact width, and you get to decide how the wrapping behaves.

Whether you're preparing plain text emails that need to fit within a 72-character standard, cleaning up code comments, formatting documentation, or making sure your output stays readable in a terminal window, this tool handles it instantly. There are no ads, no signup, and no uploads — everything happens on your device.

Unlike a simple character counter, the Wrap Text tool actually inserts newline characters (\n) at the correct positions, so the result is a genuinely reformatted piece of text ready for pasting anywhere.

How to wrap text — step by step

Using the tool takes only a few seconds. Here's the full process:

1. Paste your text into the left panel. The tool accepts any plain text — paragraphs, code, email bodies, CSV values, or notes.
2. Set the maximum line width in characters. Enter a number from 10 to 500, or click one of the preset chips (40, 50, 72, 80, 100).
3. Choose your options. Enable Break long words if you want words longer than the width to be split — useful for URLs, file paths, or code identifiers. Enable Preserve paragraphs to keep blank-line separators between paragraphs.
4. Click Wrap Text. The tool processes your text immediately and shows the wrapped result in the right panel.
5. Copy or download the output. Use the Copy Output button or the download icon to save it as a .txt file.

Example: wrapping a paragraph at 40 characters

To make it clear what the tool does, here's a before-and-after example. Notice how the tool respects word boundaries (unless you enable Break long words) and starts each new line only when the next word won't fit.

The quick brown fox jumps over the lazy dog many times in a row without stopping for a break.

As you can see, the words stay intact — no mid-word breaks — because Break long words was off. If you enabled it, a very long word like supercalifragilisticexpialidocious would be split at exactly the width limit.

Common line-width standards (reference table)

Different contexts have different "correct" widths. If you're unsure which width to use, start with one of these widely accepted values:

You can set any width between 10 and 500 in this tool, so if you're working with an unusual format, just use the exact number your target requires.

Break long words — when to use it

Normally, word wrapping moves a whole word to the next line if it doesn't fit. That's the right behaviour for regular prose. But some text contains very long tokens that simply won't fit on any line — URLs, base64 strings, hashes, file paths, or code identifiers. Without breaking, those tokens stay on their own overlong line and defeat the purpose of wrapping.

Here's when to enable Break long words:

• URLs: A 200-character URL needs to wrap or it will overflow the container.
• Base64 strings: These long alphanumeric blobs have no whitespace, so normal wrapping can't help.
• Hash values: SHA-256 hashes are 64 characters with no spaces — they need to be split.
• Long identifiers in code: Occasionally a variable or function name exceeds the width.
• File paths: Deeply nested paths can be longer than 80 characters.

Here's when to leave it off:

• Regular prose: Breaking words mid-way looks unprofessional in emails, articles, or documentation.
• Code comments: Comments read better when words aren't split.
• Poetry or song lyrics: Line breaks carry meaning; don't split words arbitrarily.

Remember: splitting a word means inserting a newline in the middle of it, which may look strange in the final output. Use this option only when strict width compliance matters more than appearance.

Preserve paragraphs — how it works

When Preserve paragraphs is enabled, the tool treats any sequence of two or more newlines as a paragraph boundary. It then wraps each paragraph independently — text from one paragraph will never bleed into the next.

This is the behaviour you want in almost every case. It respects the author's intended structure, keeping paragraphs visually separated.

When you disable it, the tool treats the entire input as one continuous stream, ignoring blank lines. This is useful when you want a strictly uniform output, or when the input has accidental blank lines that you want removed as part of the wrap.

Second paragraph with more text.

Notice how the "OFF" version merges the two paragraphs into one continuous block.

Common use cases for the Wrap Text tool

The tool handles a wide range of real-world text-formatting tasks. Here are the most popular ones:

1. Formatting plain-text emails

Plain-text emails that exceed 72 characters per line can break in some clients or become hard to read. Wrapping to 72 characters ensures your message displays correctly in Gmail, Outlook, Apple Mail, and any other client, regardless of window size. It also plays nicely with quoted replies, which prefix each line with a > character.

2. Reformatting code comments

When you move code between editors or paste it into a document, comment blocks often become too long or too short. Wrapping to 80 or 100 characters restores the standard column width that most style guides expect.

3. Preparing documentation and READMEs

Markdown files are easier to review when source lines stay under 80 characters. Many Git tools and diff viewers wrap or scroll awkwardly on long lines, so keeping source lines short improves the whole review experience.

4. Terminal output formatting

If you're building a CLI tool or logging output, keeping lines under 80 or 120 characters ensures they display without wrapping in a standard terminal window.

5. Social media text preparation

Some platforms truncate long lines in previews. Wrapping at 100 or 160 characters and pasting the result gives you more control over how your post appears.

6. Data hygiene in spreadsheets

When exporting text to CSV or spreadsheet cells, wrapping long fields makes the resulting file easier to inspect and prevents horizontal scrolling.

7. Quote formatting for academic writing

Block quotes in academic papers often have a specific column width. Wrapping to 60 or 65 characters matches common formatting requirements.

Wrap vs Unwrap — what's the difference?

These two tools do opposite things, and it's common to need both in the same workflow:

You may need to wrap and unwrap in sequence — for example, if you have a document with mixed line lengths and want a clean rewrap. The workflow is: unwrap first (to remove all existing line breaks), then wrap to your desired width. This produces a consistently formatted result no matter what the original looked like.

Tips and best practices

• Match the destination's expectations. Before wrapping, check the target. If you're pasting into a legacy system, use 72 or 80. If you're reformatting a modern codebase, 100 or 120 might be standard.
• Unwrap first for best results. If your source text already contains newlines from being copied out of an email or PDF, unwrap it first, then wrap cleanly to your chosen width.
• Keep Break long words off unless you need it. It's tempting to enable it "just in case," but mid-word splits usually look worse than a slightly-overlong line.
• Check paragraph breaks. If your output lost its paragraph structure, you probably had single newlines (not double) between paragraphs. Convert them to double newlines first, or turn Preserve paragraphs off and accept the merge.
• Test with a small sample. Paste a small representative sample of your text, run the wrap, and inspect the result before processing a large document.
• Watch out for tabs. Tabs count as one character but can visually expand. If your text contains tabs, run it through the Whitespace Cleaner first to convert them to spaces.
• Don't wrap binary or compressed data. Base64, hex dumps, and other encoded payloads may have line-length requirements of their own. Follow the format's specification.

Common mistakes and how to avoid them

1. Wrapping code without thinking about syntax

If you wrap code (not comments), you can break string literals or introduce syntax errors. Always wrap code comments only, or use a code formatter instead.

2. Using Break long words on prose

Splitting a normal English word like "information" into "informa" and "tion" looks amateurish. Only enable this for tokens that truly need it.

3. Forgetting about markdown syntax

Markdown uses trailing double-spaces to force a line break. Wrapping text with those spaces can lose them. If you need to force a line break in markdown, use two trailing spaces (or a backslash) at the end of the line.

4. Assuming all newlines are the same

Windows uses \r\n, Unix uses \n, and old Macs used \r. This tool normalizes all of them, but if you paste wrapped text elsewhere, check that the target handles LF line endings correctly.

5. Wrapping text that includes non-ASCII characters

Emojis, CJK characters, and accented letters may count as one character but visually take more space. If precise visual alignment matters, use fewer characters per line.
