A Markdown view that matches real documents
GitHub Flavored Markdown adds tables, task lists, strikethrough, and fenced code to the core syntax. The preview keeps these structures visible together instead of turning the file into plain text.

No file upload. The current source stays in this tab.
Private by design
Opening a file uses the browser File API. Rendering, syntax highlighting, diagram generation, and export happen on this device, so drafts and internal notes are not sent to a conversion service.
Markdown viewer FAQ
How do I view a Markdown file online?
Choose Open file and select a .md document, drag it onto the workspace, or paste its source into the editor. The preview updates in the same browser tab.
Does this viewer support Mermaid diagrams?
Yes. Put Mermaid source inside a fenced code block marked mermaid, or switch the workspace to Mermaid mode for a diagram-only preview.
Is my Markdown file uploaded?
No. The file is read and rendered in your browser. MDGlyph does not send the document to a server for preview or export.
