How to Add or Remove Line Breaks in Text Online

TL;DR: Need to remove messy line breaks from copied text or insert breaks at specific characters or intervals? The Add/Remove Line Breaks tool lets you clean or format any text instantly, with options for word wrapping, custom delimiters, and fixed-width formatting. Everything runs in your browser.

You paste text from a PDF into a document and every sentence is chopped into random fragments. Or you have a massive one-liner log file that needs line breaks every 80 characters. Either way, manually editing line breaks is tedious and error-prone.

TextModifier's Add/Remove Line Breaks tool handles both directions: removing unwanted breaks and inserting new ones, directly in your browser.

Why Line Breaks Cause Problems

Hard line breaks get embedded in text from many sources:

• PDFs wrap text at fixed column widths and embed a newline at each visual line end
• Emails often insert breaks at 72 or 76 characters for legacy mail clients
• Terminal output and log files break at the console width
• OCR software adds breaks wherever the scanned layout ends a line

When you paste this text into a word processor, CMS, or code editor, those breaks stay. Paragraphs become fragmented. Sentences stop mid-word. Readability drops.

Remove Line Breaks Instantly

The simplest use case: strip every line break and join text into a continuous block.

1. Paste your text into the input area
2. Optionally set a replacement character (a space, comma, or any string)
3. Click Remove Line Breaks

Leave the replacement field empty to join lines directly, or enter a space to merge lines into a flowing paragraph. You can also replace breaks with commas to create CSV-style lists.

Choose Your Line Ending Format

The tool supports both Unix (LF) and DOS (CRLF) line endings. Select the format that matches your target system before processing. This matters when you're preparing text for Linux servers, Windows applications, or cross-platform scripts.

Add Line Breaks at a Specific Character

Sometimes you need the opposite: split a single block of text into multiple lines at every occurrence of a character or phrase.

With the Add at Occurrence panel, you can:

• Enter any text to search for (a period, comma, semicolon, HTML tag, or any string)
• Choose whether to insert the break before or after the match
• Set how many breaks to insert (1 for single spacing, 2 for paragraph-style gaps)
• Toggle case sensitivity for precise matching
• Optionally remove existing line breaks first to normalize the text before splitting

This works well for reformatting minified HTML, splitting comma-separated values onto separate lines, or breaking paragraphs at sentence boundaries.

Add Line Breaks Every N Characters

Need fixed-width formatting? The Add Every N Characters panel inserts a line break after a set number of characters per line.

Key options include:

• Characters per line: set any width (40, 72, 80, 120, etc.)
• Word wrap: break at the nearest space instead of splitting words mid-character
• Escape existing line breaks: convert current \n characters to literal \n text before processing

Word wrap is enabled by default, so the tool respects word boundaries. Disable it for strict fixed-width formatting where every line must be exactly N characters.

Common Use Cases

Cleaning Up PDF Text

Copy from a PDF, paste into the tool, remove line breaks with a space as the replacement. You get a clean paragraph ready for any editor.

Formatting Data for Spreadsheets

Take a comma-separated line and add breaks after each comma. Each value lands on its own row, ready to paste into a spreadsheet column.

Wrapping Log Files

Long single-line log entries become readable when you add breaks every 120 characters with word wrap enabled.

Preparing Text for Code

Split minified CSS or JSON by adding a break after every { or ; to make the code scannable.
