I copied a paragraph out of a PDF and it broke into one short line after another. How do I fix it?

Paste it into the input, keep the default 'remove all line breaks' mode and 'replace with a space'. Each hard return turns into a space and the words flow back into a single block. For example 'When you copy\ntext from a PDF\nit breaks' becomes 'When you copy text from a PDF it breaks'. A space (not nothing) is the safe default so 'copy' and 'text' don't fuse into 'copytext'.

I want to keep my paragraphs but only fix the wrapping inside each one. Can it do that?

Yes — switch the mode to 'Keep paragraphs, join wrapped lines'. The tool treats a blank line as a paragraph boundary, so it merges the soft wraps inside each block but leaves the empty line between blocks alone. 'one\ntwo\n\nthree\nfour' comes out as 'one two\n\nthree four' — two clean paragraphs instead of one wall of text or four stray lines.

Should I replace each break with a space or just delete it?

Replace with a space for normal prose, where every line break sits between two words — deleting it would glue them together. Use 'nothing (delete)' for column data with no spaces to lose, or for a word split by a hyphen at the line end like 'won-\nder' that should rejoin as 'wonder'. The custom option lets you join lines with a comma, a pipe, or any separator, handy for turning a vertical list into one comma-separated line.

What is the difference between CRLF, CR and LF, and why does it matter here?

They are the three ways software marks the end of a line. Windows uses CRLF (carriage return + line feed, '\r\n'), classic Mac used CR alone ('\r'), and Unix/macOS use LF ('\n'). If a tool only strips '\n' it leaves orphan '\r' carriage returns that show up as boxes or odd gaps. This tool normalizes CRLF and CR to LF first, so every line break is handled no matter which system produced the text.

Will removing line breaks accidentally stick two English words together?

Not if you use the default 'replace with a space' — every break becomes a space, so 'the end\nof line' stays 'the end of line', never 'the endof line'. Words only fuse if you deliberately choose 'nothing (delete)', which is exactly what you want for a hyphenated word break but wrong for ordinary sentences. When in doubt, keep the space and turn on 'collapse runs of spaces' to tidy up any double spaces afterward.

Paste PDF text into a form without the column effect

You copied a clause from a contract PDF to drop into a web form, but it arrives as a tall stack of half-width lines because the PDF wrapped every line. Paste it here, leave the defaults, and the words flow back into one block of prose that fits the field. No more manually deleting a return at the end of every line while you watch your cursor crawl down the page.

Flatten a vertical list into one comma-separated line

You have a column of names, SKUs or email addresses, one per line, and a system that wants them comma-separated on a single line. Switch the replacement to custom and type ", " — every line break becomes a comma and a space, and the whole column collapses into one tidy line you can paste straight into the field.

Clean text scraped from a chat or email before reusing it

Forwarded email and pasted chat logs are full of soft wraps and double blank lines from quoted replies. Turn on keep-paragraphs mode plus collapse-blank-lines, and you keep the real paragraph breaks while the accidental wrapping and the empty-line noise disappear — ready to drop into a doc or a knowledge base.

Rejoin a hyphenated word split across two lines

OCR and justified PDFs love to break a word with a hyphen at the line end: 'inter-' then 'national' on the next line. Set the replacement to 'nothing (delete)' so the break vanishes and the halves rejoin as 'international', then proofread for any genuine line-break spaces you actually wanted to keep.

What this tool does

Free online tool to remove line breaks and join wrapped text back into flowing sentences. Text copied out of a PDF, a Word column, an email or a code comment usually carries a hard line break after every visual line, so it lands in your form or chat box chopped into a tall narrow column. Paste it here and pick what each break becomes: a space (safe for prose so words stay separated), nothing at all (for column data or hyphenated words), or any custom string like a comma or a pipe. Two modes: remove every line break, or keep the blank line between paragraphs and only merge the soft wraps inside each paragraph. Extra switches collapse multiple blank lines into one, trim leading and trailing spaces on each line, and squeeze runs of spaces down to a single space. Carriage returns from Windows (CRLF) and classic Mac (CR) are normalized first, so no stray boxes are left behind. Live output, line and character counts, one-click copy, and a shareable URL that reproduces your exact text and settings. 100% client-side, nothing is uploaded.

Common pitfalls

Deleting line breaks (replace with nothing) on ordinary prose, which glues the last word of one line onto the first word of the next — 'the end' + 'of line' becomes 'the endof line'. Use a space for sentences and reserve delete for column data and hyphen splits.
Using all-remove mode when you meant to keep paragraphs. All-remove collapses the entire document, blank lines included, into one continuous string. If you want the gaps between paragraphs to survive, pick keep-paragraphs mode instead.
Forgetting that stray carriage returns can survive a naive newline strip. Text from Windows carries CRLF; deleting only the line-feed leaves a carriage return that renders as a box. This tool normalizes first, but if you paste the result somewhere that re-wraps, re-run it rather than hand-editing.

Privacy

Your text is processed entirely in your browser tab with plain JavaScript — it is never uploaded, logged, or sent to any server, so confidential contracts, customer lists and private notes stay on your machine. One caveat: the shareable URL encodes your input and options in the query string, so pasting a 'share link' into chat records that text in the recipient server's access log. For anything sensitive, use the copy button and paste the cleaned text instead of sharing the link.
