Remove Line Breaks

The Remove Line Breaks tool strips unwanted newlines from pasted text and joins everything back into a single paragraph or line, replacing each break with a space, a comma, or nothing at all. It exists for one very specific and very common annoyance: text copied out of a PDF, an email client, or a scanned document that arrives with a hard line break at the end of every visual line, rather than only at the end of each paragraph.

That kind of text looks fine while it's still formatted in its original layout, but the moment it's pasted somewhere with different column width — a CMS text box, a spreadsheet cell, a chat message — every one of those mid-sentence breaks becomes a visible, awkward gap. Writers pasting a quote from a PDF report, support staff copying a customer's email into a ticketing system, and developers cleaning up text scraped from a webpage all run into the same problem: real paragraph breaks need to survive, but the accidental ones inside a sentence need to go.

Under the hood, every line-ending style is treated the same way — Windows-style CRLF, Unix-style LF and old Mac-style CR are all normalized before replacement, so it doesn't matter which system the original text came from. After the chosen replacement is applied, an optional cleanup pass collapses any resulting double spaces and trims the ends, so joining 'Hello \n World' with a space produces a clean 'Hello World' rather than 'Hello World' with a leftover double gap.

One thing this tool intentionally doesn't do is distinguish an intended paragraph break from an accidental mid-sentence one — it removes every line break in the input uniformly. For text that mixes real paragraph breaks with wrapped-line breaks, it works best as a first pass: join everything into one block, then manually reinsert paragraph breaks where they actually belong.
