Paste some text above, then press Clean text.
Text Cleaner tidies up messy text in one step. Paste anything copied from a website, PDF, email, or word processor, then pick the cleanups you want: strip HTML tags, remove extra spaces, drop line breaks, delete special characters, trim each line, remove empty lines, and convert curly smart quotes to straight ones. The cleaned result appears instantly, ready to copy. Everything runs in your browser, so your text never leaves the page.
What is the Text Cleaner?
Text copied from the web or from formatted documents almost always carries invisible baggage: stray HTML tags, double spaces, non-breaking spaces, hard line breaks in the middle of sentences, and typographic characters like curly quotes, en dashes, and ellipses. Pasted into a plain field (a code editor, a spreadsheet cell, a CMS box, a CSV file) that baggage breaks formatting, throws off character counts, or shows up as odd symbols. A text cleaner normalises all of it back to plain, predictable text.
Each option targets one common problem. Strip HTML removes everything between angle brackets and keeps only the readable words. Remove extra spaces collapses runs of spaces and tabs down to a single space. Remove line breaks joins wrapped lines into one continuous paragraph, which is handy when text was copied from a narrow column or a PDF. Remove special characters keeps letters, numbers, and ordinary punctuation while dropping emoji, control characters, and other symbols. Fix smart quotes swaps the curly quotation marks and apostrophes that word processors insert for the straight ASCII versions that code and data files expect.
The order matters, and the tool applies the steps in a sensible sequence. HTML is stripped first so the remaining text is plain, then smart quotes and special characters are normalised, and finally whitespace and line handling are applied. Because every option is a toggle, you stay in control: leave smart quotes alone if you are cleaning prose for publication, or turn on every option for the most aggressive plain-text scrub. The before and after character counts show exactly how much was removed.
When to use it
- Cleaning text copied from a website so it pastes into a CMS or document without stray HTML and formatting.
- Flattening text pulled from a PDF, where every line ends in a hard break, into clean paragraphs.
- Converting curly smart quotes and dashes to straight ASCII before pasting code, CSV data, or config values.
- Tidying user-submitted or scraped text by removing emoji, control characters, and double spaces.
- Normalising notes from different sources into one consistent plain-text style before sharing.
How to use the Text Cleaner
- Paste or type your text into the input box.
- Tick the cleanup options you want, such as strip HTML, remove extra spaces, or fix smart quotes.
- Press Clean text (or just edit a toggle) to apply the selected cleanups.
- Check the before and after character counts to see how much was removed.
- Press Copy to put the cleaned text on your clipboard.
Formula & method
Worked examples
You paste a paragraph wrapped in HTML p tags reading Hello "world" with three spaces in the middle, with strip HTML, remove extra spaces, and fix smart quotes turned on.
- Strip HTML removes the p tags, leaving: Hello "world"
- Fix smart quotes leaves the already-straight quotes unchanged: Hello "world"
- Remove extra spaces collapses the triple space to one: Hello "world"
- Trim each line removes any leading or trailing spaces.
Result: Hello "world"
You paste three lines copied from a PDF, with a blank line between them, and turn on remove line breaks and remove extra spaces.
- Input is: This is line one. (newline) This is line two. (blank line) This is line three.
- Remove line breaks replaces every newline with a space.
- Remove extra spaces collapses the resulting double spaces to single spaces.
- Trim removes the leading and trailing space.
Result: This is line one. This is line two. This is line three.
What each cleanup option does
| Option | Effect |
|---|---|
| Strip HTML tags | Removes anything between angle brackets, keeps the readable text only |
| Remove extra spaces | Collapses runs of spaces and tabs down to a single space |
| Remove line breaks | Joins all lines into one, replacing each break with a space |
| Remove special characters | Drops emoji and symbols, keeps letters, numbers, and basic punctuation |

| Remove empty lines | Deletes lines that contain only whitespace |
| Fix smart quotes | Converts curly quotes, dashes, and ellipsis to straight ASCII |
Common smart characters and their straight replacements
| Smart character | Replaced with |
|---|---|
| Curly single quotes and apostrophes | Straight apostrophe ' |
| Curly double quotes | Straight double quote " |
| En dash and em dash | Hyphen - |
| Ellipsis character | Three dots ... |
Common mistakes to avoid
- Removing line breaks when you meant to keep paragraphs. Remove line breaks joins everything onto one line. If you want to keep paragraph structure, leave it off and use remove empty lines or trim each line instead.
- Stripping HTML you actually wanted to keep. Strip HTML deletes all tags. If your goal is to clean the markup while keeping it as code, turn this option off, since it returns only the readable text.
- Fixing smart quotes on prose meant for publishing. Curly quotes and em dashes are correct typography for articles and books. Only convert them to straight quotes when the destination (code, CSV, config) needs plain ASCII.
- Expecting special-character removal to keep emoji. Remove special characters drops emoji and uncommon symbols by design. If you need to keep them, leave that option unchecked and clean only whitespace and HTML.
Glossary
- Smart quotes
- Curly typographic quotation marks and apostrophes that word processors insert automatically in place of straight ASCII ones.
- HTML tag
- A markup element written between angle brackets, such as a paragraph or bold tag, that controls formatting but is not part of the readable text.
- Whitespace
- Spaces, tabs, and line breaks. Extra whitespace is often invisible but inflates character counts and breaks alignment.
- Line break
- A newline character that moves text to the next line. Hard breaks copied from PDFs often split sentences awkwardly.
- Special character
- Any character outside letters, digits, and common punctuation, such as emoji, control codes, or unusual symbols.
Frequently asked questions
What does a text cleaner do?
A text cleaner removes unwanted formatting and characters from text. This tool can strip HTML tags, remove extra spaces and line breaks, delete special characters, trim lines, remove empty lines, and convert curly smart quotes to straight ones, all in a single step that you control with toggles.
Is my text uploaded anywhere?
No. The cleaning runs entirely in your browser with plain JavaScript. Nothing you paste is sent to a server or stored, so it is safe to clean private or sensitive text.
How do I clean text copied from a PDF?
Paste it in, then turn on remove line breaks and remove extra spaces. PDFs usually add a hard break at the end of every visual line, so joining the lines and collapsing the resulting double spaces gives you clean, flowing paragraphs.
What is the difference between strip HTML and remove special characters?
Strip HTML removes only the markup tags between angle brackets and keeps all the readable words. Remove special characters works on the plain text and drops symbols like emoji and control characters while keeping letters, numbers, and basic punctuation.
Why would I convert smart quotes to straight quotes?
Code editors, CSV files, JSON, and many config formats expect straight ASCII quotes. Curly quotes pasted from a word processor can cause syntax errors or show up as garbled symbols, so converting them prevents those problems.
Can I undo the cleanup?
The original text stays in the input box, so you can untick options or press Clear and start again. The cleaned result appears separately in the output box, leaving your source text untouched until you replace it.
