questions, answered.

Practical details about opening, editing, previewing, and exporting Markdown files with Marksmith Forge.

What files can Marksmith Forge open?

Marksmith Forge can open .md, .markdown, and .txt files. You can also start a new document and save the source as Markdown.

Can I export Markdown to PDF or Word?

Yes. You can export Markdown to a selectable PDF or an editable Microsoft Word DOCX file, as well as HTML, EPUB 3, and LaTeX.

Does Marksmith Forge work offline?

Yes. Editing and file conversion run locally on your computer. No account, cloud upload, or internet connection is required.

Does the Markdown editor support math equations?

Yes. Marksmith Forge renders inline and display mathematics with KaTeX and preserves supported math across compatible export formats.

Can Marksmith Forge render Mermaid diagrams offline?

Yes. Mermaid is bundled with the app and renders locally in preview and supported exports. The toolbar includes starters for flowcharts, sequence and class diagrams, Gantt charts, timelines, mind maps, and more.

Does Marksmith Forge include Spell Check and Auto-Correct?

Yes. Both are optional, disabled by default, and work independently using local resources. Spell Check offers suggestions, Ignore, and Add to Dictionary. Both tools skip code, Mermaid diagrams, URLs, link targets, and math or LaTeX expressions.

What’s new in version 1.3.2?

The upcoming 1.3.2 release brings a unified Marksmith Forge menu to Windows File Explorer. Right-click .md or .markdown files to export to PDF, DOCX, HTML, LaTeX, or EPUB, or select a single file to open in the editor. Export individual files or batches in the background while your current document and unsaved changes stay intact, with Marksmith Forge notifications for export results.

The Microsoft Store edition adds the submenu to Windows 11’s first right-click menu. The standalone Windows installer provides the same actions in the classic menu, under Show more options on Windows 11.

Exports are saved beside the source file, replacing any existing export with the same name. See the 1.3.2 release notes for details.

Which operating systems are supported?

Marksmith Forge supports Windows 10 and Windows 11 through the Microsoft Store, plus macOS on Apple-silicon Macs through a direct DMG download.
