How to Use

Clean Markdown: Paste your text and click this button to convert all Markdown formatting into plain text. The meaning and structure stay intact — only the formatting symbols disappear.

Copy: Copies the cleaned text to your clipboard for immediate pasting into any app, document, or editor.
Delete: Deletes all content in the input field to start fresh.
Theme Options:
- Light: Bright interface for daytime use.

- Auto: Matches your device's theme preference.

What Gets Cleaned

Text formatting: **bold**, *italic*, ***bold italic***, ~~strikethrough~~, __underline__.
Headers: # H1 through ###### H6 — symbols removed, heading text kept.
Links & images: [text](url) → text only; ![alt](image.jpg) → alt text or URL.
Code blocks: fenced ```code``` and inline `code` — formatting removed, content kept.
Lists: bullet asterisks * removed; dashes - and pluses + kept as-is.
Blockquotes: > quoted text — marker removed, text kept.
Tables: converted to simplified plain text, one row per line.
Horizontal rules: standalone ---, ***, ___ lines removed.
Checkboxes: [ ] and [x] markers removed.
HTML comments:  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

All regular text — letters, numbers, and line breaks.
Dashes - and pluses + used as list markers — kept as-is.
URLs and link destinations — preserved where they carry meaningful content.
Content inside code blocks — the code itself is kept, only the fencing is removed.
Emojis and special symbols — this tool targets Markdown formatting only.

Perfect For

AI-generated content: ChatGPT, Gemini, Claude, Copilot, and other AI assistants format responses with Markdown. Convert it to plain text before pasting into emails, reports, or professional documents.
Copy-pasting from documentation: Clean up Markdown from GitHub READMEs, wikis, or any technical docs before reusing the text elsewhere.
Content repurposing: Strip formatting from blog posts, articles, or notes written in Markdown before publishing to platforms that don't support it.
Any Markdown text: If it has unwanted formatting symbols and you need clean plain text, paste it here.

How It Works

Markdown Cleaner uses a two-pass processing strategy. The first pass handles complex structures line by line: code fences, tables, blockquotes, headers, links, images, and inline emphasis. The second pass cleans up any multi-line emphasis patterns that span across line boundaries. No AI involved, no server calls, no external libraries. The same input always produces the same output.
