What Is Markdown Preview and How Do You Use It While Writing?

Updated

Markdown preview is a rendered view of your Markdown source, shown alongside or instead of the raw text so you can see headings, tables, code blocks, images, and links as they will appear in the final output. A live, synced preview updates as you type and scrolls with the editor, which is the typical workflow in a dedicated editor such as Markdown Monster on Windows. Use it when you need to check formatting and layout while drafting; use manual export (to HTML or PDF) when you need a finished file to share or publish.

Live preview vs. manual export

These are two different jobs, and mixing them up causes most confusion:

Task What happens When to use it
Live/synced preview The editor renders your Markdown continuously in a preview pane and keeps it scrolled in step with the source Drafting, checking tables and code blocks, catching broken links or images
Export to HTML or PDF The document is converted to a file on disk (or a selection is copied as HTML to the clipboard) Delivering a finished document, publishing, archiving

Markdown Monster describes its preview as "collapsible, synced, live" — you see output as you type and scroll. Export is a separate action: you can write Markdown to PDF or HTML on disk, or copy a Markdown selection as HTML to the clipboard.

The typical writing workflow

  1. Write in the editor pane. Type Markdown with syntax highlighting active.
  2. Watch the preview update. The preview pane re-renders as you type; scrolling the editor scrolls the preview in sync.
  3. Insert complex elements with helpers. For images, links, tables, and code, use raw markup or the editor's UI helpers — for example, paste an image from the clipboard or drag one in from Explorer or the built-in file browser.
  4. Check the rendered result. Confirm headings, tables, code blocks, images, and links look right before exporting or publishing.
  5. Export or publish when done. Convert to HTML or PDF, or publish directly to a supported blog service.

What the preview should render correctly

A good preview is not just bold and italics. Check that it handles:

  • Headings — and, in Markdown Monster, a document outline lets you jump between open document headers.
  • Tables — the editor includes a two-way table editor, so edits in either direction stay consistent.
  • Code blocks with syntax highlighting — the HTML preview can display syntax-colored code snippets for most coding languages.
  • Images — pasted, dragged, or embedded via the file browser.
  • Links — including relative paths to local files.

Common preview problems and fixes

Preview looks stale or out of sync with the cursor. Confirm the preview is set to synced/live mode rather than a manual refresh. If scrolling has drifted, scroll the editor to force a re-sync; a collapsed preview pane can also look frozen — expand it.

Images are missing. Usually a path problem. Relative image paths break when the document moves or when the preview resolves paths from a different base folder. Re-insert the image through the file browser or drag-and-drop so the path is written correctly, and keep images in a folder relative to the document.

Relative links don't resolve. Same cause as missing images: the link is relative to the document's location. Check the file is saved in the expected folder before trusting the preview.

Raw HTML doesn't render as expected. Preview renderers vary in how much embedded HTML they pass through. If a block of raw HTML shows as text or renders oddly, simplify it to Markdown equivalents where possible and verify in the exported HTML, which is the format that matters for publishing.

Code blocks lose their colors. Syntax coloring depends on the language being identified on the code fence. Label the fence with the language name and re-check the preview.

Preview options worth knowing

  • Light and dark app themes, with individually selectable and customizable preview and editor themes — useful for matching the preview to your target site's look.
  • Copy selection as HTML — handy when you need a fragment for a CMS rather than a whole exported file.
  • Publishing targets — if your blog supports WordPress, MetaWeblog, Jekyll, or Medium, Markdown Monster can publish with one click, and can also edit and republish or convert existing HTML posts to Markdown. Preview first, then publish, so formatting problems are caught before they go live.
