Frequently asked questions about Free MD Viewer
Is my data stored in the cloud?
No. The tool runs entirely in your browser. Nothing you type or open ever leaves your device.
Can I save my work permanently?
Yes. On Chrome/Edge, you can save directly back to the original file. On other browsers, it downloads a copy. Your work is also kept as a draft in the browser session.
What happens if I refresh the page?
Your work is kept as a draft in the browser, so a refresh won't lose it.
Can I use this offline?
Yes. Once loaded, it works completely offline. On Chrome/Edge, you can install it as a PWA so .md files open directly, even without internet.
