Line Break Inserter
Add Consistent Line Breaks or Wrappers to Every Line
Need to use Line Break Inserter right now?
Preparing a list for code — wrapping each line in quotes for an array, or adding HTML tags around each item — requires touching every single line the same way, which is exactly the kind of repetitive task that's fast to automate and slow to do by hand. This tool applies a consistent prefix, suffix, or fixed-width wrap to every line of pasted text at once.

About Line Break Inserter
Text Wrapper reshapes how a block of text is broken into lines, in one of two genuinely different ways depending on what you actually need. "Wrap to line width" performs classic word wrapping: it re-breaks your text so that no line exceeds a character limit you set, breaking only at word boundaries so words are never split apart mid-way. This is exactly the logic a terminal, a fixed-width code comment block, or an old-school plain-text email needs, since none of those environments wrap long lines automatically the way a modern web page or word processor does.
This matters more than it might seem for specific technical contexts: writing a comment block in source code where a style guide caps line length at 80 characters, formatting plain-text content for a system that displays monospace text without wrapping (like some terminal output, fixed-width reports, or legacy plain-text email clients), or preparing a block of text for a physical medium like a label or receipt printer with a known character-per-line limit. Manually inserting line breaks at the right character position by counting characters is exactly the kind of tedious, error-prone task worth automating.
"Add prefix/suffix per line" solves a completely different problem: wrapping every line of existing text with a consistent string before and after it, without changing where the line breaks fall. Common uses include wrapping each line of a list in quotation marks to prepare it for pasting into code as an array of string literals, wrapping each line in a specific HTML tag (like `<li>` and `</li>` to quickly turn a plain list into HTML list items), or adding a consistent bullet character or comment marker (like `// `) to the start of every line in a block of code or notes.
Both modes work on the entire block of text at once, respecting existing line breaks as the unit being processed, and update instantly as you adjust the width or the prefix/suffix text, so you can see the effect immediately rather than guessing and re-copying.
How it works
- Paste your text. Enter the text or list you want to reformat.
- Choose a wrapping mode. Wrap to a fixed line width, or add a consistent prefix/suffix to every line.
- Set your options. Enter your character width, or your prefix and suffix strings.
- Copy the result. The reformatted text updates instantly and is ready to copy.
