Markdown

The Markdown preview shows your Markdown files as formatted, readable documents, and it lets you edit them in place. It opens in the preview sidebar, a preview tab, or fullscreen.

Phials recognizes the extensions .md, .markdown, and .mdc. For where previews appear and how Phials chooses one, see File Previews.

Editor and Raw modes

The Markdown preview has two modes, switched from the toolbar:

  • Editor (the default): a formatted, block-style view where your headings, lists, and emphasis appear as you would expect, and you can edit directly.
  • Raw: the plain Markdown source in a syntax-highlighted code editor, for precise edits or copying source.

This page focuses on viewing. For the full writing experience, including saving, undo and redo, parse notes, and the 1 MB size limit, see The Markdown Editor.

Relative images and links resolve from the folder that contains the file, so a reference like ![](photo.jpg) shows correctly in the preview without changing your source.

Inline HTML in a Markdown file is not rendered in Editor mode. Switch to Raw to see and edit it literally.

Fullscreen

Use the fullscreen control in the toolbar (or open the file in a preview tab) for a larger, focused layout with the same Editor and Raw modes. Press Escape to leave fullscreen. Phials asks before discarding any unsaved changes.
