MD Clipper

Save any web page as a Markdown file with one click.

MD Clipper is a Chrome extension that converts any web page into a clean Markdown file with frontmatter — in just one click. ■ Key Features - One-Click Conversion: Click the toolbar icon to instantly download the current web page as a Markdown file. - Right-Click Menu: Right-click on any page and select "Save as Markdown" for quick saving. - Smart Content Extraction: Powered by Mozilla's Readability.js, the same engine behind Firefox Reader View. Automatically removes ads, navigation bars, sidebars, footers, and other clutter — extracting only the article body. - High-Quality Markdown: Turndown.js converts HTML to Markdown with support for headings, lists, links, bold, code blocks, tables, and more. - YAML Frontmatter: Each file includes metadata (title, URL, date, domain) in YAML format at the top of the document. ■ Output Example --- title: "Article Title" url: "https://example.com/article" date: 2026-05-17 domain: "example.com" --- # Article Heading The article body continues in Markdown format... ■ Customization - Subfolder Setting: Choose a subfolder within your Downloads directory via the options page. For example, set "md-clipper" to save all files into a dedicated folder. - Title Editing: Edit the article title in the popup before saving — this title is used for the filename. - Preview: Review the converted Markdown in the popup before saving. - Clipboard Copy: Instead of downloading, copy the Markdown text directly to your clipboard with one click. ■ Supported Formats Turndown.js accurately converts the following HTML elements to Markdown: - Headings (h1–h6) → ATX-style # syntax - Paragraphs and line breaks - Bold, italic, and strikethrough - Ordered and unordered lists - Links and images - Fenced code blocks and inline code - Blockquotes - Tables (custom rule for Markdown table conversion) ■ Libraries Used - Readability.js (Mozilla, Apache 2.0 License): The same library used in Firefox Reader View. Analyzes DOM structure to identify and extract article content with high accuracy. - Turndown.js (MIT License): A JavaScript library for converting HTML to Markdown. Offers extensive options and custom rule support for high-quality output. Both libraries are bundled within the extension package. No code is loaded from external servers. ■ Privacy & Security - Fully Local Processing: All conversion happens entirely in your browser. No web page content is ever sent to any external server. - Minimal Permissions: Only the minimum required permissions are used. The activeTab permission ensures access only when you explicitly activate the extension. - No Data Collection: No personal information, browsing history, or behavioral data is collected, stored, or transmitted. - Open Source: The full source code is available on GitHub for anyone to review. ■ Who Is This For? - Anyone who wants to save blog posts and news articles in Markdown format - Users of knowledge base tools like Obsidian, Notion, Logseq, or similar apps - Developers who want to archive technical articles and documentation locally - Researchers who want to clip web content efficiently in Markdown - Anyone who wants clean article text without ads and sidebars ■ How to Use 1.
