Remove Line Breaks

Remove line breaks — delete or replace newline characters

PicoToolkit removes newline characters so you can join wrapped paragraphs, prepare single-line fields for CSV/JSON, or normalize pasted text. The tool deletes all line breaks; use an intermediate "add suffix" step if you need a separator (space, comma, etc.) preserved between lines.

How to use

1. Paste your text into the editor.
2. Open the menu: Remove → Line breaks.
3. The tool removes all newline characters (both LF and CRLF are supported).

• If you want a specific separator between lines (space, comma), first run Add prefix or suffix to append that character to each line, then remove line breaks.
• To keep a single paragraph break only, run Remove → Empty lines first to collapse duplicate blank lines, then remove line breaks.

Common use cases

• Join wrapped lines from copied emails or PDFs into a single paragraph.
• Turn a vertical list into a single CSV field by adding a comma suffix then removing line breaks.
• Create single-line JSON values or database fields from multi-line input.
• Normalize user-submitted text before analysis or import.

Examples (copy/paste)

Example 1 — Simple join (remove all line breaks)

 Input (mixed line endings): Hello world. This is line two. This is line three.

After Remove Line Breaks: Hello world. This is line two. This is line three. 

Example 2 — Preserve a single space between lines (use Add suffix)

 Step 1 — Add suffix " " (space) to each line using Add prefix or suffix: Hello world.␣ This is line two.␣ This is line three.␣

Step 2 — Remove Line Breaks: Hello world. This is line two. This is line three. 

Example 3 — Produce a comma-separated inline list (use Add suffix ",")

 Step 1 — Add suffix "," to each line: apple, banana, cherry,

Step 2 — Remove Line Breaks: apple,banana,cherry, (Optional) Remove the trailing comma with Find and Replace (/text/find-and-replace). 

Example 4 — Clean CSV field with embedded newlines

 Input cell value: "Address: 123 Main St. Suite 4"

Workflow:

Add suffix " " (space) or " | " to each line.
Remove Line Breaks. Result: "Address: 123 Main St. Suite 4" (This keeps words separated so the CSV field remains readable.) 

Tips & edge cases

• Both LF (\n) and CRLF (\r\n) line endings are handled — you don't need to normalize them first.
• The tool removes every newline. If you need to preserve paragraph breaks, use Remove → Empty lines to collapse duplicates, or add a marker suffix to paragraph-ending lines before removing breaks.
• If trailing/leading spaces matter, run Trim before or after removing line breaks.
• For very large inputs, browser memory affects performance — split the input if the page becomes slow.
• Combine with Find and Replace to remove leftover separators or with Character Counter to verify lengths after processing.

Related tools

• Add prefix or suffix — append a character (space, comma) to each line before removing breaks.
• Remove Empty Lines — collapse duplicate blank lines to preserve paragraph structure.
• Trim — remove unwanted spaces around lines.
• Find and Replace — remove trailing separators or perform regex transforms after joining lines.
• Character Counter — check final lengths for CSV or field limits.
• Convert Newline To Comma — a shortcut for the common add-suffix + remove-line-breaks workflow.

FAQ

Will this remove both LF and CRLF line endings?

Yes. The tool supports both LF (\n) and CRLF (\r\n) and will remove them the same way.

How can I preserve a separator (space, comma) between lines?

Add the separator to the end of each line first using Add prefix or suffix, then run Remove Line Breaks. This keeps a visible separator where lines joined.

Can I keep paragraph breaks instead of merging everything into one line?

The Remove Line Breaks tool deletes all newlines. To preserve paragraph breaks, first collapse duplicate blank lines with Remove → Empty lines, or add a distinct marker at paragraph ends and post-process after joining.

Are there input size limits?

There is no explicit server-side limit shown. Practical limits depend on your browser and device memory. If the browser slows down, split the text into smaller chunks.
