Why Android can't open .md out of the box
Markdown has no registered MIME type on Android, so most file managers don't know what an .md file is — you'll get “Can't open file”, or a share sheet full of text editors that show raw markup. The content is fine; Android just needs an app that understands the format.
Reading .md properly on Android
With Read.md installed, .md opens as a formatted document:
- From any file manager or Downloads: tap the file, pick Read.md.
- From Drive, Telegram, email: use Share / Open with → Read.md.
- From GitHub: browse repositories inside the app and read every .md rendered.
Typography built for reading, dark mode, adjustable text size, a table of contents for long files, syntax-highlighted code, and Mermaid diagrams — fully offline.
One-off file? Use the browser
The free web viewer renders .md in Chrome without installing anything — and without uploading your file anywhere.
