Clean Text Online

Remove formatting, extra spaces, invisible characters and AI artefacts from any pasted text, instantly and without your text ever leaving the browser.

Why clean your text?

Every time you copy and paste text from one source to another, you drag along much more than the words. Pasted text carries hidden formatting: double spaces, tabs, stray line breaks, curly quotes, em dashes and, above all, invisible characters that you cannot see but that are still there. Cleaning text is the process of removing all that noise so you are left with just the content in plain text.

That noise has real consequences. A hidden zero-width space can break a word search, invalidate a password or misalign a table. A non-breaking space (NBSP) instead of a normal space throws off the layout in a CMS. And the curly quotes or em dashes that Word and AI tools now insert so often change how your text looks when you publish it on a site that expects standard characters. That is why a good text cleaner is essential for anyone who writes, publishes or codes every day.

With this tool you can remove formatting entirely or pick only the cleanups you need. Every option is independent and the result appears instantly, so you see exactly how the text looks before copying it.

What is cleaning text?

Cleaning text means removing all formatting, extra spaces and hidden characters from a text to leave only the content in plain text, ready to reuse anywhere.

Unlike a simple "paste without formatting", which only strips visual styles (bold, colors, fonts), cleaning text goes further: it also normalizes spacing, removes invisible characters, unifies quotes and dashes, and can strip accents, numbers, punctuation, emojis or links depending on what you tick. It is an à-la-carte cleanup, not an all-or-nothing button.

The end goal is for the text to be predictable: the same characters you see are the ones that are there, with no hidden surprises between the letters.

How to clean text in 3 steps

1. Paste the text

Copy the text from Word, a PDF, a website or ChatGPT and paste it into the input area on the left. There is no length limit.

2. Choose options or a preset

Tick the cleanups you need across the six option groups, or press a preset like "Clean AI text" to apply a ready-made combination with a single click.

3. Copy the result

The clean text appears instantly in the area on the right. Copy it to the clipboard or download it as a .txt file.

What each cleaning option does

Spaces

Collapses any run of two or more spaces into one, trims the start and end of each line, and converts tabs into spaces. For a more specific space cleanup, use remove extra spaces.

Lines

Removes empty lines or joins the whole text into a single paragraph by removing line breaks. If you only want the latter, the remove line breaks tool offers more join modes.

Invisible

Removes zero-width characters, converts Unicode spaces (like NBSP) into normal spaces and strips non-printable control characters. This is the most important part for cleaning text copied from the web.

AI / ChatGPT

Normalizes curly quotes and em dashes, removes Markdown symbols and strips emojis. Designed for text generated by AI tools.

Formatting

Removes HTML tags (and decodes entities like  ), strips links and URLs, or leaves the text as ASCII only by discarding any non-standard character.

Text

Removes accents and diacritics (keeping ñ and ç), strips punctuation or numbers and, with the dropdown, switches to lowercase, UPPERCASE or sentence case. To work with accents only, use remove accents.

How to clean text copied from ChatGPT or AI

The text produced by ChatGPT and other AI tools usually comes with a set of very specific formatting artefacts. The most common are curly quotes (" " instead of straight ones), em dashes (— and –), Unicode spaces that are not normal spaces, Markdown symbols (bold asterisks, heading hashes) and, in some cases, zero-width characters. All of them make the text look or behave differently when you paste it into an editor, a CMS or a form that expects standard characters.

The "Clean AI text" preset applies all these normalizations at once: it converts quotes and dashes to their simple form, removes invisible spaces, strips Markdown and emojis, and collapses extra spaces. The result is a homogeneous text with standard characters, ready to publish or reuse.

We want to be honest on one point: this tool cleans the formatting and artefacts of the text so it looks uniform and professional. It is not designed to "fool" any AI detector, nor does it promise that a text will pass as human; its value is leaving the text clean, not hiding its origin.

Remove invisible characters and hidden Unicode

Invisible characters are Unicode codes that have no width or visible shape but still occupy a position in the text. The most common are the zero-width space (U+200B), the word joiner (U+2060), the byte-order mark (U+FEFF) and the non-breaking space or NBSP (U+00A0). They appear when you copy from web pages, formatted documents or some AI tools.

Even though you cannot see them, they cause harm: they stop a search from finding a word that "seems" to be there, invalidate passwords and form fields, break JSON or CSV files and throw off layout. Spotting them by eye is nearly impossible, and that is exactly the problem.

With the invisible characters option (or the "Basic cleanup" preset) you remove the zero-width ones in one go; with "Unicode spaces" you turn NBSP into normal spaces; and with "Control characters" you strip the non-printable codes. It is the most reliable way to make sure the text you see is exactly the text that is there.

When should you clean text?

📋

Text pasted from Word or PDF

When you copy from Word, Google Docs or a PDF, the text drags hidden formatting, odd line breaks and extra spaces. Clean it all at once to paste it into a CMS or an email without surprises.

🤖

ChatGPT and AI text

AI-generated text includes curly quotes, em dashes, Unicode spaces and sometimes Markdown. The "Clean AI text" preset normalizes them so the text looks clean and consistent.

🔍

SEO and web publishing

A title or meta description with double spaces or invisible characters clutters your HTML. Cleaning the text before publishing keeps your code and content spotless.

💾

Data, code and forms

Invisible characters break searches, validations and comparisons. Convert the text to ASCII only or strip control characters before importing it into another application.

Frequently asked questions

Is cleaning text here free?

Yes, the text cleaner is 100% free, with no character limit and no sign-up. Use it as many times as you like.

Is my text uploaded to a server?

No. All cleaning happens locally in your browser; your text never leaves your device. That means you can clean sensitive information with peace of mind.

What are invisible characters and why should I remove them?

They are Unicode characters with no visible shape, such as the zero-width space (U+200B) or the non-breaking space (NBSP). They sneak in when you copy from the web and break searches, passwords, validations and layout. The invisible-characters option removes them.

Can I clean text copied from ChatGPT or AI?

Yes. The "Clean AI text" preset normalizes curly quotes and em dashes, removes Unicode spaces, Markdown and emojis, and collapses extra spaces. It cleans the formatting and artefacts; it does not promise to "fool" any AI detector.

How is this different from removing accents or extra spaces separately?

This tool combines all those cleanups in a single pass. If you only need one specific task, use the dedicated remove extra spaces, remove line breaks or remove accents tool.

Do I lose content when cleaning the text?

No: only the formatting and the characters you tick are removed; the words are kept. You can undo the changes by pasting the original text back into the input area.

Does it work with text from Word, PDF or web pages?

Yes, it is ideal for text pasted from Word, Google Docs, a PDF or a website, which usually drags hidden formatting, stray line breaks and irregular spacing.

How do I leave the text as ASCII only?

Turn on the "ASCII only" option to remove any character outside basic English, or use the "ASCII only" preset, which also strips accents and control characters. It is useful for code, identifiers and legacy systems.
