Frequently asked questions
Is my Markdown file uploaded?
No. The file is read by your browser and shown on your own device. Nothing is sent to a server, and it is gone when you close the tab.
How do I open a Markdown file without installing software?
Drop the .md, .markdown file on this page. It opens straight away in the Markdown Viewer, on Windows, macOS, Linux, Android and iPhone alike.
What if my Markdown file doesn't open?
The viewer checks the file's content, not just its name. If it is damaged or not really a Markdown file, you'll see an error or can switch to the hex view to look at the raw bytes.
Can I convert Markdown to another format?
Yes. The free file converter turns Markdown files into other formats in your browser as well, without uploading them.
