Description

QL Markdown is a macOS extension that renders Markdown files in Finder's Quick Look at GitHub-grade quality. Just select a .md file and press the space bar — a clean, well-formatted preview appears instantly with no need to open a separate app. ■ Supported formats .md, .markdown, .mdown, .mkd extensions ■ Key features • Full GitHub Flavored Markdown (GFM) support — tables, checkboxes, autolinks, strikethrough • Automatic YAML Front Matter detection, displayed as a tidy table at the top of the document • Footnotes and definition lists • KaTeX math rendering — recognizes $...$, $$...$$, \(...\) • Mermaid diagrams — flowcharts, sequence, Gantt, class diagrams, etc. • highlight.js code syntax highlighting (190+ languages) • Automatic light/dark mode tracking — preview switches instantly when the system appearance changes ■ Fully local operation (network-isolated) All fonts, scripts, and stylesheets are bundled inside the app. Every feature works identically without an internet connection, and no requests are sent to external servers. http/https requests are double-blocked using both Content Security Policy (CSP) and WKContentRuleList, so you can use the app with confidence in secure environments. ■ App Sandbox compatible Complies with Apple's App Sandbox and Hardened Runtime. The app does not access any files other than those the user explicitly selects. ■ Local image support (optional) When a Markdown document references images in the same folder (e.g. ![](images/foo.png)), grant read access to that folder once via the host app's "Grant Folder Access" button, and images will appear in Quick Look as well. When access is not granted, a dotted-box placeholder is shown along with the alt text so you can immediately see which image is missing. http/https images are blocked per the network policy. ■ Large file handling Markdown files up to 5 MB are processed. Larger files are truncated at a line boundary, and a banner at the top notes the truncation. Truncated code blocks or math blocks are automatically closed so the output is never broken. ■ Korean / Japanese / Chinese encoding auto-detection In addition to UTF-8, files saved as UTF-16 (with BOM), Shift-JIS, or EUC-KR are detected automatically and displayed correctly. ■ How to use 1. Launch the app once to register the Quick Look extension. 2. Select a .md file in Finder and press the space bar. 3. (Optional) To view local images, grant folder access from the host app's "Grant Folder Access" button. ■ System requirements • macOS 14.0 (Sonoma) or later • Universal binary — Apple Silicon and Intel Macs ■ Open source licenses The full text of bundled third-party library licenses (cmark-gfm, highlight.js, KaTeX, Mermaid, github-markdown-css) is available in the app menu under Help → "Open Source Licenses".
