When you need to remove line breaks
Line breaks arrive uninvited from a lot of places. Text copied from a PDF has a break at the end of every printed line. Email clients hard-wrap long messages at 72 or 78 characters. Terminal output, log files, subtitles and OCR results all come out line by line. Even chat assistants sometimes break a list item across lines. Whatever the source, the fix is the same: decide which breaks are real and remove the rest.
Remove every line break
Choose Remove all line breaks when the whole text should be one line: a search query, a spreadsheet cell, a form field that rejects newlines, a URL that was wrapped in an email, or a single sentence you want to paste into a chat box without accidentally sending it early. Pick nothing as the replacement for URLs and codes so no spaces are inserted; pick a space for sentences.
Keep paragraphs
Choose Keep paragraph breaks for prose that is hard-wrapped but still has blank lines between paragraphs, which is how most plain-text emails and README files look. Lines inside each paragraph are joined, and the blank lines survive, so you get flowing paragraphs that reflow correctly in Word, Google Docs or a CMS.
Fix text copied from a PDF
PDF text rarely has blank lines between paragraphs; every line just ends. The Fix hard-wrapped PDF text mode uses punctuation instead. If a line ends in a full stop, question mark, exclamation mark, colon or closing quote it is treated as the end of something and its break is kept; otherwise the line is joined to the next one. Words that were split with a hyphen at the margin, such as infor- and mation, are put back together. The result is not perfect for every layout, but it turns a wall of short lines into readable paragraphs in one paste, and you can correct the few remaining joins by hand.
Line breaks are the only thing this page changes. If the same text also has smart quotes, em dashes or stray markdown, the AI Text Cleaner handles all of that in one pass and has its own single-line option.
Frequently asked questions
What is the difference between removing all line breaks and keeping paragraphs?
Remove all joins every line into one continuous block. Keep paragraph breaks only joins lines inside a paragraph and leaves a blank line wherever there was one, so the text still reads as separate paragraphs.
How does the PDF fix mode decide which lines to join?
It looks at how each line ends. A line ending in a full stop, question mark, exclamation mark, colon or closing quote is treated as a real end and its line break is kept. Any other line is assumed to be wrapped mid-sentence and is joined to the next one with a space. Words split with a hyphen at the line end are stitched back together.
Should I replace line breaks with a space or with nothing?
Use a space for prose so words do not run together. Use nothing when the breaks fall inside a long string that must not contain spaces, such as a URL, a token or a base64 block that was wrapped by an email client.
Why does text copied from a PDF have a line break after every few words?
PDFs store text as positioned lines, not flowing paragraphs. When you copy, each visual line comes out as its own line with a newline at the end, and the paragraph structure is lost. The PDF mode here reconstructs paragraphs from the punctuation.
Does it change anything else in my text?
Only line breaks and, if the option is on, runs of spaces. Quotes, dashes, emojis and formatting are untouched. For those, use the AI Text Cleaner.
