What it does
Text copied from a PDF often arrives with a line break at the end of every line, words cut in half by hyphens, double spaces and odd symbols. This tool tidies it up. Paste the text, tick what you want fixed, and the clean version appears below, ready to copy. Each option has a one-line explanation, and the before and after counts show what changed.
Nothing is uploaded; the cleaning runs on your device. After cleaning, you can count the result with word counter, change its case with case converter, or check two versions side by side with compare documents.
How to use it
- Paste your text in the top box.
- Tick or untick the fixes. The result updates at once.
- Press Copy the clean text, or Use as my text to run a second pass.
What each option does
- Join broken lines: single line breaks become spaces, blank lines stay as paragraph breaks.
- Remove hyphenation: “docu-” then “ment” on the next line becomes “document”. A word that is meant to have a hyphen at a line end, such as “well-known”, may be joined too, so read the result.
- Remove extra spaces and extra blank lines: tidy the gaps.
- Strip bullets and list numbers: remove the signs at the start of lines.
- Straight or curly quotes: pick one style for all quotes and apostrophes.
- Remove emojis and hidden characters: deletes pictures, zero-width marks and control characters, and turns non-breaking spaces into normal ones.
Worked example
The pasted text “This is a docu-” / “ment that wraps” / “over two lines.” becomes “This is a document that wraps over two lines.” with joining, hyphenation and spaces turned on.
FAQs
Can it keep my paragraphs? Yes. Turn on Join broken lines and blank lines between paragraphs are kept.
Will it fix tables? No. Tables copied from PDFs lose their layout; clean the text and rebuild the table by hand.
Is my text kept? No, it stays in your browser tab.
Where the numbers come from
- Unicode character ranges for the hidden characters, emojis and quotes. Rules are fibub's own; always read the result before you use it.
Standard scientific values, such as constants, atomic weights and melting points, are facts found in every textbook; we name where ours were checked. If you are an author or publisher and want a value, a credit or a table changed or removed, tell us and we will act quickly.
