How It Works
Three Ways to Convert
Use the web app for quick conversions, the Chrome extension for in-browser convenience, or batch processing when you have a stack of files to handle.
The Conversion Process
Upload or drop
Drag files into the web app, use the Chrome extension on any page, or select files from your computer.
Parse structure
MDSpin analyzes the document to identify headings, tables, lists, and reading order — not just raw text.
Generate Markdown
Clean, semantic Markdown is generated with preserved hierarchy. Tables stay as tables, lists keep their structure.
Copy or download
One-click copy to clipboard or download as a .md file. For batch jobs, merge everything into a single document.
Drag, Drop, Done
The web app is the fastest way to convert a document. Drop your file into the converter, and MDSpin returns clean Markdown in seconds. No account needed, no data stored on our servers after processing.
