Prepare the input
Paste text whose physical line breaks are known to be unwanted. Inspect PDF or OCR output for hyphens at line ends because joining with a space cannot decide whether a word should be recombined.
Join hard-wrapped text into one flow
Line Break Remover
Trim non-empty lines and join them with a space, no separator, or comma-space locally, with no claim that removed breaks were semantically accidental.

Product guide
Flatten physical lines without guessing document semantics
Nirmion removes empty lines, trims each remaining line, and joins the sequence using the selected separator. It does not distinguish a visual wrap from an intentional paragraph or list boundary.Choose the rule
Space is the safest general prose default. None concatenates line content directly. Comma plus space converts each non-empty line into a simple inline list, but embedded commas are not escaped.
Review the output
Read the entire single-line result and restore any meaningful paragraph, address, verse, code, or list boundaries. For CSV or structured data, use a delimiter-aware converter rather than this plain-text join.
How it works
Trim, remove empty rows, and join in source order
Windows and classic Mac line endings are normalized, each physical line is trimmed, empty lines are filtered out, and the remaining values are joined with exactly the selected separator. The operation is deterministic and preserves line order, but it does not parse punctuation, hyphenation, HTML, or table structure.
Useful when
Repair hard wraps and build simple inline lists
The tool works best when you already know that physical line breaks are transport noise rather than content structure.
- Join prose copied from a PDF, terminal, narrow email, or OCR output after checking end-of-line hyphenation.
- Concatenate a split identifier, token, or wrapped URL with no separator when each line break is known to be artificial.
- Turn one simple value per line into a comma-separated display list for manual use, not into standards-compliant CSV.
Questions answered
Line Break Remover questions
Practical boundaries matter with text tools. These answers explain what is measured, what is retained, and when a manual review is still needed.
Are blank lines included as separators?
No. Blank lines are removed before joining, so repeated blanks do not create repeated spaces or commas.
Will split hyphenated words be repaired?
No. A hyphen remains and the chosen separator is added after it. Decide manually whether the hyphen belongs to the word.
Is comma mode valid CSV?
Not necessarily. It does not quote values containing commas, quotes, or newlines. Use a CSV-aware tool for machine-readable output.
Privacy and retention
Your draft stays on your device.
Nirmion performs these operations with browser JavaScript. The workspace does not call the catalogue API with your source text, and completed-job content is kept only in this component memory for re-download.
A downloaded file remains in your browser downloads, device storage, backups, and any location where you share it. Clear or close the page when working on a shared device, and avoid pasting secrets into extensions or third-party clipboard managers.
Tool details
Remove hard line breaks with an explicit join separator
Nirmion Line Break Remover joins trimmed non-empty physical lines using a space, no separator, or comma-space. It is useful for hard-wrapped prose, split identifiers, copied terminal output, and simple manual lists when the user understands the original structure.
