PreviewMarkdown
macOS / Productivité
PreviewMarkdown provides QuickLook file previews and file icon thumbnails for documents created using the popular markdown markup format.
The app provides two app extensions: Markdown Previewer and Markdown Thumbnailer, which can be viewed and managed in macOS’ System Preferences > Extensions. The app itself is simply a container for these extensions.
You must run the app first to gain these benefits.
PreviewMarkdown supports the following markdown features:
*italics* or _italics_
**bold** or __bold__
~~Strikethroughs~~

Quoi de neuf dans la dernière version ?
• We’ve added some extra settings:
° Control preview window size: small (42% of main screen; standard QuickLook size), medium (50% of main screen) or large (75% of main screen)
° Set your preferred preview whitespace margin.
° Set all Markdown file thumbnails to match Finder’s display mode under macOS 26.1+.
• We’ve added new, more intuitive graphic for unchecked checkboxes.
• We’ve fixed some reported bugs:
° Front matter detection now works correctly when horizontal rules are also included in the Markdown.
° Image URLs are no longer converted to lower case.
