Markdown to TXT

A zero-install, offline Markdown to TXT converter that runs entirely in your browser.

Use it to turn Markdown notes, AI outputs, documentation drafts, copied web content, and Obsidian notes into clean plain text. It supports manual input, drag-and-drop, batch files, output rules, multilingual UI, copy, and download.

Built with AI coding models. Designed from real workflow problems.

Highlights

• Fully static: just index.html, styles.css, script.js, sw.js, and manifest.webmanifest.
• Offline-first: no server, no CDN, no upload. Installable as a PWA.
• Batch-ready: drag multiple .md, .markdown, or .txt files.
• Three conversion styles: Standard, Clean, and Structured.
• Conversion presets: AI dataset cleaning, documentation archive, publishing.
• Output rule toggles for links, code blocks, and front matter.
• Copy current result, download current, merge-download all, or download ZIP.
• Dark mode with system preference detection and manual toggle.
• Multilingual UI (20 languages) with LTR and RTL support.
• Works directly from local files or GitHub Pages.

Download

Download source archives from GitHub Releases, or open index.html directly in your browser.

Conversion Modes

• Standard: removes Markdown syntax while keeping readable paragraphs, list structure, links, and code content.
• Clean: produces compact plain text for pasting into simple editors or forms.
• Structured: preserves heading hierarchy and code boundaries for readable archives.

Supported Syntax

Beyond standard Markdown, the converter handles:

• Inline and block math ($...$, $$...$$).
• Footnotes ([^id] and definitions).
• Auto-links (<http://x>).
• Reference link definitions.
• Admonitions (!!! note ...).
• Definition lists.
• Task lists with nested indentation.
• Inline HTML allowlist (<kbd>, <sup>, <sub>, etc.).

Privacy

Markdown to TXT does not upload content. Normal conversion runs completely in the browser on your machine.

Clipboard access may require HTTPS or localhost in some browsers. Manual paste still works.
