How it works

Three steps from file to Markdown. No installation, no account, no data leaving your browser.

01

📁 Choose your file or URL

Drag a file to the conversion area, click to select it from your system, or switch to URL mode and paste the link to any public file (PDF on a CDN, DOCX on a server, etc.).

02

⚙️ The browser processes it

The file is converted entirely in your browser using JavaScript libraries (mammoth, pdf.js, SheetJS, Turndown, PapaParse). No bytes are sent to any server. The process is instant for small files.

03

✓ Edit, copy or download

The resulting Markdown appears in an editor. You can modify it, copy it to the clipboard with one click, or download it as a .md file ready to use in GitHub, Notion, Obsidian or any editor.
