Safe Reading

Reader is designed to open Markdown files without letting document content control the app or change your files.

Reader does not run HTML or scripts included in a Markdown file. HTML-like content appears as text.

  • Links to websites and email addresses open in your usual Windows app.
  • Links that try to run scripts or open unsupported locations are blocked.
  • Links to headings stay inside the current document.
  • Images stored beside the Markdown file can appear in the document.
  • Images from the web can reveal that you opened a document to the image host.
  • Use the remote-image setting to allow or block images from the web.

Reader is read-only. Opening, searching, zooming, or changing the reader theme does not modify the Markdown file.
