What is the Text Cleaner?
The Text Cleaner is a free online tool that removes unwanted line breaks and whitespace from text copied out of PDFs, web pages, messengers, or code editors in a single pass. Copying a sentence from a PDF often inserts a hard line break at the end of every line, and moving documents around tends to leave a mess of consecutive spaces, tabs, and blank lines. With a few checkboxes, this tool turns that into one clean block of text.
It goes beyond basic line-break and space removal: it also strips and normalizes characters that are invisible on screen but stay in the data and break search, sorting, and code parsing — zero-width characters (U+200B/200C/200D/FEFF) and special spaces like NBSP and full-width spaces. Line breaks can be handled with three modes (remove all, keep paragraphs, replace with space), the result updates as a live preview while you type, and before/after character, line, and byte counts are shown side by side. Everything runs in your browser and nothing is uploaded.
Key Features
Three line-break modes
Choose remove all (join into one line), keep paragraphs (preserve blank-line breaks), or replace with a single space — whatever fits the situation.
Space & blank-line cleanup
Collapse consecutive spaces and tabs into one, or remove all spaces entirely, plus trim each line and delete blank lines in a single pass.
Zero-width & special space removal
Strips invisible zero-width characters (ZWSP, ZWNJ, ZWJ, BOM) and normalizes NBSP and full-width spaces — a feature rarely found elsewhere.
Live preview + statistics
The result refreshes instantly as you change input or options, and before/after character, line, and byte counts show exactly how much was removed.
How to Use
- Paste the text you want to clean into the input box, or drag and drop a .txt file.
- Choose a line break mode: remove all, keep paragraphs, or replace with a space.
- Check the options you need: collapse spaces, trim lines, remove blank lines, strip zero-width characters, normalize special spaces.
- Review the live preview on the right and the before/after statistics.
- Use Copy to put it on your clipboard, or Download to save it as a .txt file.
When to Use It
Clean up PDF copies
Reconnect sentences broken line-by-line when copied from papers, e-books, or report PDFs into a natural paragraph.
Writing & publishing
Tidy up stray blank lines and extra spaces when moving text into a blog, Notion, or Word for a clean piece.
Data & code cleanup
Remove hidden zero-width characters and NBSP from copied code, CSV, or logs to prevent parsing and search errors.
Prep for translation/summary
Clean up unnecessary line breaks and spaces before pasting into an AI or translator for more accurate results.
Frequently Asked Questions
When I copy from a PDF, every line gets a line break. How do I remove them?
Choose the “Remove all (one line)” or “Replace with space” line break mode. If you also want to keep paragraph breaks, pick “Keep paragraphs” — it preserves paragraphs separated by blank lines and only merges the awkward single line breaks inside each paragraph into spaces.
What are “zero-width characters” and why remove them?
Zero-width characters (U+200B, U+200C, U+200D, U+FEFF, etc.) have no visible width on screen but still exist in the data. They sneak in when you copy from the web or documents and cause search, sorting, and code-parsing errors as well as mismatched character counts. This tool strips them in one click.
Can it also handle special spaces like NBSP?
Yes. The “Normalize special spaces” option converts NBSP (U+00A0), full-width space (U+3000), narrow spaces, and other Unicode spaces into regular spaces. Combined with “Collapse extra spaces,” everything is neatly reduced to single spaces.
What is the difference between “Collapse extra spaces” and “Remove all spaces”?
“Collapse extra spaces” reduces two or more consecutive spaces/tabs to a single space while keeping the spacing between words. “Remove all spaces” deletes every space, including the ones between words, so the text becomes glued together. If both are on, “Remove all spaces” takes priority.
Is my text sent to a server?
No. All cleaning runs in your browser with JavaScript. Your text and any uploaded file are never sent to or stored on a server, so you can safely clean sensitive documents.
Can I save the result as a file?
Yes. Click the “Download” button above the result to save the cleaned text as a UTF-8 encoded .txt file (cleaned.txt). You can also use “Copy” to put it on your clipboard and paste it elsewhere.
