Text Cleaner

Clean Extra Spaces, Blank Lines, Emojis, and AI Markdown

Text Cleaner instantly transforms messy text into clean, plain format. Remove extra spaces, blank lines, emojis, and Markdown formatting from AI responses — ChatGPT, Claude, Gemini, Copilot, and other AI assistants — as well as social media posts and any document. Uses simple pattern matching rules — does not analyze, rewrite, or modify your content meaning. Built for any language — spacing and punctuation handling are fully Unicode-aware, supporting every script Unicode defines. All processing happens locally in your browser — your data never leaves your device. No registration, no ads, no limits, forever free.

How It Works

• Clean Spaces: Removes both extra spaces (multiple spaces between words) and redundant blank lines (consecutive empty lines). Perfect for cleaning up messy copy-pasted text from Word, PDF, or email — fast even on full-length documents.
• Clean Emojis: Removes all emojis, symbols, invisible characters, and emotional icons. Spacing and punctuation are automatically adjusted so the remaining text reads naturally. Perfect for extracting pure text from social media posts, chat messages, or emoji-heavy content.
• Clean Markdown: Removes all Markdown formatting including **bold**, *italic*, [links](url), > quotes, headers, code blocks, and tables. Converts AI-formatted responses back to plain text while preserving meaning.
• Clean All: The most powerful option — combines all three methods at once. Removes extra spaces, blank lines, emojis, and Markdown formatting instantly. Get clean, professional text ready to use anywhere.
• Undo / Redo: After any clean action, tap Undo to restore the original text — the button switches to Redo, so you can tap again to bring back the cleaned version. Resets automatically when you edit or delete the text.
• Copy: Copies cleaned text to clipboard for easy pasting into documents, emails, or any application.
• Delete: Deletes all content in the input field to start fresh.
• Theme Options:
  • Light: Bright interface for daytime use.
  • Dark: Dark interface that's easy on eyes at night.
  • Auto: Matches your device's theme preference.

Perfect For AI Text Cleaning

AI assistants like ChatGPT, Claude, Gemini, and Copilot format their responses using Markdown for better readability. When you copy that text to emails, documents, or presentations, the formatting symbols become clutter. Text Cleaner removes all of it instantly — giving you clean, professional text ready to use anywhere.

What Gets Cleaned

Spaces and Blank Lines:

• Multiple consecutive spaces, tabs, and Unicode spaces → single space.
• Multiple empty lines → maximum one empty line.
• Leading and trailing whitespace removed from each line and the entire text.

Emoji Removal:

• Face and people emojis: 😀 😂 🥺 😍 🤔 👋 🙏 👀 and all variations.
• Objects, nature and symbols: 🌟 🔥 💡 🎉 🚀 ❤️ 💯 ✅ and all pictographic icons.
• Flag emojis: 🇫🇮 🇩🇰 🇮🇸 🇸🇪 🇳🇴 🇨🇭 🇳🇿 🇨🇦 and all regional indicator symbol sequences.
• Keycap emojis: *️⃣ #️⃣ 0️⃣–9️⃣ and all digit keycap sequences.
• Skin tone modifiers: All Fitzpatrick scale modifiers (👍🏻 👍🏼 👍🏽 👍🏾 👍🏿) attached to any emoji.
• Zero-width joiners and invisible characters: ZWJ sequences, variation selectors, and other invisible Unicode characters used to compose complex emoji.
• Dingbats and miscellaneous symbols: ☀️ ☁️ ☎️ ✉️ and legacy symbol characters in the Unicode Miscellaneous Symbols block.
• Spacing cleanup: Stray spaces left next to punctuation (. , ! ? : ; ) … · ؟ ؛ ، · 。 、 ！ ？) after emoji removal are automatically removed. If an emoji removal leaves behind multiple spaces at that spot, they're collapsed into one — this only happens right where an emoji was removed, not elsewhere in your text.
• Quotation marks and parentheses: Stray spaces next to quotation marks or parentheses wrapping a removed emoji are cleaned up too — straight ("), curly (“ ” ‘ ’), CJK corner brackets (「 」 『 』), and ( ). This only applies when the quotes are properly paired; an unmatched one is left as-is. Straight single quotes (') are left alone to avoid breaking contractions like don't.

Markdown Removal:

• Text formatting: **bold**, *italic*, ***bold italic***, ~~strikethrough~~, __bold__ and _italic_ (underscore variants of bold and italic).
• Headers: # H1 through ###### H6 — symbols removed, heading text kept.
• Links and images: [text](url) → text only; ![alt](image.jpg) → alt text or URL. Reference-style links like [text][id] and their [id]: url definitions are resolved the same way.
• Code blocks: Fenced ```code``` and inline `code` — formatting removed, content kept.
• Lists: Bullet asterisks * removed; dashes - and pluses + kept as-is.
• Indentation and line-end spaces: Leading and trailing whitespace on every line is stripped, since Markdown is converted to plain text — this flattens nested list indentation and blockquote continuation lines. Content inside fenced code blocks (```) is exempt and keeps its original indentation.
• Blockquotes: > quoted text — marker removed, text kept.
• Tables: Converted to simplified plain text, one row per line.
• Horizontal rules: Standalone ---, ***, ___ lines (surrounded by blank lines) removed.
• Checkboxes: [ ] and [x] markers removed.
• HTML comments: <!-- comment --> removed entirely.
• Escaped HTML tags: Backslash-escaped tags like \<div> are removed entirely.
• Escape sequences: Backslash escapes like \*, \_ converted to their literal characters.
• Math notation: $$formula$$ and $formula$ — delimiters removed, content kept.
• Footnotes: [^1] references and definitions cleaned up.

What Stays Untouched

• Regular text: Letters, numbers, and line breaks.
• List markers: Dashes - and pluses + used as list markers are kept as-is.
• Ordered list numbers: 1., 2., 3.... are kept as-is; only extra spacing after the number is tidied.
• Mentions and hashtags: @name and #tag are left untouched, even if they contain characters that would otherwise be read as formatting.
• Numbers next to asterisks: Expressions like 3*5 or 2**3 are left as-is, not mistaken for bold or italic formatting.
• Intentional spacing: A single space between words and a single blank line between paragraphs are left as-is — only extra, duplicate spaces and blank lines are collapsed.
• URLs and link destinations: Bare URLs (not wrapped in Markdown link syntax) are left untouched. Inside [text](url) links, only the display text is kept — the URL destination is dropped unless it matches the text.
• Content inside code blocks: The code itself is kept, only the fencing is removed.
• Non-pictographic symbols: Regular punctuation and special characters are untouched — only emoji and invisible Unicode characters are targeted.

Best For

• AI and Markdown content: Clean output from ChatGPT, Claude, Gemini, Copilot, and other AI assistants that use Markdown.
• Social media and messaging: Remove emojis from X, Facebook, Instagram, TikTok, or text from Slack, Discord, WhatsApp, and Telegram.
• Messy formatting: Fix extra spaces and blank lines from copy-pasted text from Word, Google Docs, PDF, or email.

Not Recommended For

• Programming code or technical syntax (use dedicated code formatters).
• Mathematical formulas or equations requiring special formatting.
• Structured data files (CSV, JSON, XML).
• Content where indentation or exact spacing matters outside code blocks (nested lists, ASCII diagrams, manually aligned text) — "Clean Markdown" strips leading/trailing whitespace on every line, and "Clean Spaces"/"Clean All" also collapse repeated spaces within a line. Only content inside fenced code blocks (```) is exempt.

Tip: For messy text with extra spaces and blank lines, use "Clean Spaces". For social media or emoji-heavy content, use "Clean Emojis". For AI responses with Markdown formatting, use "Clean Markdown". For everything at once, use "Clean All". Not sure about the result? Use "Undo" to compare with the original.

Need to clean the links inside your text? Text Cleaner keeps the surrounding text tidy, but doesn't change the links themselves. For removing tracking parameters (UTM, fbclid, gclid…) from those links, Clean Share Link is a free companion tool.
