Free Online Markdown Viewer
Open an MD file or paste Markdown to read a wide document preview. Free, no sign-up, and processed in your browser.
Markdown preview
Open a .md file, drop it here, paste Markdown, or try the example to start reading.
Files stay in this browser. Changes are saved as a local viewer draft; Clear deletes it. Storage may be unavailable in private browsing.
How to open an MD file online
Choose Open .md File or drop a .md, .markdown, or .txt file into the workspace. Paste Markdown opens the source panel so you can paste text with your usual keyboard or touch controls.
Read first, edit when needed
The viewer opens in a single preview column on desktop and mobile. Switch to source or a side-by-side view on desktop; text changes update the preview immediately. Fullscreen gives the document more space.
Supported Markdown formatting
Preview headings, paragraphs, bold, italics, strikethrough, links, quotes, simple lists, tables, and fenced code. Raw HTML is displayed as text. Full GFM compatibility, syntax highlighting, and math rendering are not provided by this viewer.
Review README files, notes, and drafts
Read a downloaded README, check AI-generated Markdown, or review meeting notes before sharing. Use the editor for writing and formatting, or a conversion tool for HTML, PDF, and Word output.
Privacy and browser processing
Document text is read locally and is not uploaded to MDFormats. The viewer draft is separate from Editor and Word drafts and remains in this browser until cleared or browser storage is removed. If storage is blocked, viewing and downloading still work.
Markdown Viewer FAQ
How do I open an MD file online?
Choose Open .md File, select your local file, and read the preview. You can also drag a file into the workspace.
Can I preview a GitHub README?
Yes. Download the README and open it here, or paste its Markdown source. This viewer does not fetch GitHub URLs. Relative links depend on their destination; local repository images are not loaded.
Do I need to install software?
No. Open the tool in a modern browser; no account or installation is required.
Are my files uploaded?
No. Reading and previewing happen in your browser. A local draft is saved on this device when browser storage is available.
How is Viewer different from Editor?
Viewer starts with reading. Editor provides writing tools, find and replace, and formatting. Both can preview Markdown.
How can I download the original Markdown?
Choose Download .md. It saves the current source text, including any changes you made, rather than converting it to HTML.
Does it work on a phone?
Yes. The mobile view starts in preview mode; switch to source to paste or edit, then return to preview.
Does it support tables and code blocks?
Yes, simple Markdown tables and fenced code blocks are supported. Code is shown as plain code without syntax highlighting.
