Remove Line Breaks

What this tool does

Text copied from a PDF, a terminal, an email or a plain-text file often arrives with a line break every seventy characters. Those breaks were part of the layout, not the writing, and they follow the text into whatever you paste it into. This tool takes them out.

The four modes

Keep paragraphs

The default, and usually the right one. Lines inside a paragraph are joined with a space, while blank lines are treated as genuine paragraph breaks and kept. Hard-wrapped prose comes out as real paragraphs.

Replace with a space

Every line break becomes a single space, producing one continuous block of text.

Remove completely

Lines are joined with nothing between them. Useful for a key, hash or token that was wrapped across several lines — and wrong for prose, which needs the space.

Replace with a separator

Every line break becomes whatever you type: a comma and a space, a pipe, a semicolon. This is how you turn a column of values into a comma-separated list.

Example

Three lines reading The harbour office, moves in March. Deliveries,should be redirected. become one sentence with Keep paragraphs, andThe harbour office, moves in March. Deliveries, should be redirected. with a comma separator.

A note on the paragraph heuristic

Keeping paragraphs relies on an assumption: that a single line break is soft wrapping and a blank line is a deliberate break. That assumption is right for most prose and wrong for anything where short lines are intentional — poetry, addresses, song lyrics, a list without bullets. In those cases the lines will be joined together. Read the result before using it.

Useful cases

• Making PDF text usable in a document or a message.
• Turning a column of values into a comma-separated list.
• Rejoining a token or key that wrapped in an email.
• Flattening text before pasting it into a field that only accepts one line.
