mdview Desktop is a read-only Markdown viewer for Windows 11 that opens .md and .markdown files as formatted documents, including when launched by double-clicking them. It is designed for offline reading rather than editing, and renders GitHub-flavored Markdown, syntax-highlighted code, tables, Mermaid diagrams, and LaTeX math locally. Other features include document search, a table of contents, light and dark themes, folder browsing and linked files, multiple tabs, and live reload when a document changes. It supports files up to 25 MB, loading long documents as readers scroll. The current release is version 1.0.1 for 64-bit Windows; Windows 11 on ARM should also work, while Windows 10, Linux, and macOS are not yet supported. The installer is unsigned, so Windows SmartScreen may warn users.
The free plan includes document reading, search, tables, Mermaid, math, and large-file support. Pro adds folder and tab features, live reload and session restore, reading customization, advanced table and diagram controls, code copying, and PDF export; new users receive a seven-day trial, and one Pro account can activate up to three computers. The app requires no account or internet connection for ordinary reading, and does not upload files. However, Pro licensing and trial activation require contacting mdview.io; optional anonymous usage statistics can be disabled. Saving a PDF sends the document to mdview.io for generation, though the service says it does not retain it. The app is not an editor and does not directly open standalone .mmd files.
