What is the Text Cleaner?

Clean and format text instantly with our free online text cleaner. Remove extra spaces, line breaks, duplicate lines, HTML tags, and invisible characters. Perfect for fixing text copied from emails, PDFs, websites, or AI tools like ChatGPT.

Features include quick presets for common tasks (PDF cleanup, code formatting, AI output cleaning), a live preview of your cleaned text, detailed statistics on what was removed, and powerful find-and-replace with regex support. All processing happens locally in your browser for complete privacy.

How it works

This text cleaner works by applying a series of transformations to your input text in a specific order:

  1. HTML Processing - If enabled, strips HTML tags and decodes HTML entities first
  2. URL/Email Handling - Converts mailto links and href attributes to plain text
  3. Character Normalization - Removes invisible characters, normalizes quotes and dashes
  4. Find & Replace - Applies your custom find/replace pattern (with optional regex support)
  5. Whitespace Management - Removes line breaks, extra spaces, and trims lines
  6. Duplicate Removal - Identifies and removes duplicate lines while preserving order
  7. Case Conversion - Transforms text to upper, lower, title, or sentence case
  8. Sorting - Arranges lines in the specified order (alphabetical, by length, or reversed)
  9. Line Numbers - Optionally adds numbered prefixes to each line

All processing happens instantly in your browser. The tool shows you exactly what was changed with detailed statistics on characters removed, duplicates found, and other cleaning metrics.

Frequently asked questions

What is a text cleaner tool?

A text cleaner is an online utility that removes unwanted characters, formatting, and whitespace from text. It helps clean up text copied from emails, PDFs, websites, or AI outputs by removing extra spaces, line breaks, HTML tags, invisible characters, and other formatting issues.

Is this text cleaner free to use?

Yes, this text cleaner is completely free with no registration required. All text processing happens in your browser - your data never leaves your device, ensuring complete privacy and security.

Does the tool store my text?

No. This text cleaner runs entirely in your browser using client-side JavaScript. Your text is never sent to any server or stored anywhere. Once you close the tab, everything is gone.

Can I remove line breaks but keep paragraphs?

Yes! Enable "Remove line breaks" and keep "Preserve paragraphs" checked. This removes single line breaks while keeping double line breaks (paragraph breaks) intact. This is perfect for fixing text copied from PDFs or emails.

How do I remove duplicate lines?

Enable "Remove duplicate lines" in the Advanced Options. By default, it's case-insensitive (treating "Hello" and "hello" as duplicates). Check "Case-sensitive" if you want to keep different capitalizations as unique lines.

What are invisible characters?

Invisible characters include zero-width spaces, non-breaking spaces, and other Unicode characters that are invisible but affect text formatting. They often appear when copying from websites, Word documents, or AI tools. Enable "Remove invisible chars" to strip them.

Can I find and replace text with regex?

Yes! Enter your pattern in the Find field, enable the "Regex" checkbox, and enter your replacement. The tool supports standard JavaScript regular expressions for powerful pattern matching and replacement.

How do I normalize smart quotes?

Smart quotes (curly quotes like '' and "") can cause issues in code and certain applications. Enable "Normalize quotes" to convert them to straight quotes (' and ") for better compatibility.

What's the AI output preset for?

The AI output preset is designed to clean text from ChatGPT, Claude, and other AI tools. It removes invisible characters, normalizes quotes and dashes, removes extra spaces, and trims whitespace - common issues with AI-generated text.

Can I strip HTML tags from text?

Yes! Enable "Strip HTML tags" to remove all HTML markup while preserving the visible text content. The tool also decodes common HTML entities like &, <, and  .
