Why wrap text at a fixed width
Long lines are hard to read and hard to handle. A paragraph that runs to two hundred characters forces the eye to travel a long way back to the start of the next line, and readers lose their place. Many formats also demand a maximum width: plain-text emails traditionally wrap at around 72 characters, code comments are kept under 80 or 100, terminals are 80 columns wide, and some old systems reject or truncate longer lines outright. Even when nothing forces it, a consistent width makes text look deliberate and cared for.
Wrapping by hand means counting characters and choosing break points, which is slow and breaks the moment you edit a word. An automatic wrapper does it in a click, and re-wrapping after an edit is just as fast, so the width stays consistent through revisions.
How this tool works
Paste your text and set the width in characters. The tool uses greedy word wrapping: it packs words onto a line until the next word would push the line past the width, then starts a new line. Words are never split in the middle unless you allow it, so the output reads naturally, with breaks only at spaces. By default the tool wraps each paragraph separately, respecting your existing line breaks, so blank lines between paragraphs survive and headings stay on their own lines.
Long words get special handling. A single word longer than the width, such as a URL, cannot fit on any line by the normal rule. With the break-long-words option on, such a word is split across lines at the width boundary. With it off, the word stays whole and its line simply exceeds the width, which is often better for URLs and identifiers that must not be broken. The tool reports the longest line in the result, so you can see at a glance whether any line still exceeds your target.
When to use it
Use it to prepare plain-text emails, README files, documentation and comments that should fit a classic width. Use it to reformat text copied from a PDF or a web page, where lines may have been broken at arbitrary points by the layout, by first joining and then re-wrapping at your chosen width. Use it to tidy pasted content for systems with line-length limits, and to make long chat messages and forum posts easier to read.
It is also useful before printing or displaying text in a fixed-width context, such as a terminal, a code editor sidebar, or an embedded display. Wrapped text degrades gracefully there, while unwrapped text gets cut off or forces horizontal scrolling.
What wrapping does not do
Wrapping changes line breaks, not words. It does not hyphenate, so a line may end a little short of the width when the next word does not fit; that ragged edge is normal for word wrapping and is not a flaw. It does not justify text or balance line lengths, and it does not understand sentences, so it will not prefer breaking after a full stop. If you need typographic justification, a word processor or typesetting tool is the right place.
Also note that wrapping is a one-way cosmetic change in the sense that the original paragraph breaks are preserved but the exact original line breaks inside a paragraph are replaced. Keep the original if you need to re-wrap at a different width later, since re-wrapping wrapped text gives the same result, but only if you join the lines first or let the tool treat each line as its own paragraph.
Tips for well-wrapped text
For prose, 70 to 80 characters is a comfortable reading width; for code comments, match your project’s limit. If your text contains many URLs, turn off long-word breaking so links stay clickable and intact. After wrapping, skim the result for a line that looks oddly short, which usually means a long word forced an early break nearby, and adjust the width by a few characters if it bothers you. Everything runs in your browser, so your text is never uploaded.
