Extract text from your PDF files and convert it into standard Markdown syntax locally. Fast, secure, and client-side.

How it works

This tool converts PDF documents to Markdown client-side using the PDF.js parsing engine.

When a PDF file is loaded, it is read into an array buffer and decoded to extract character arrays and text dictionaries page-by-page.

Our parser parses the geometric coordinate alignments of text segments. It groups adjacent segments on the same horizontal line, detects paragraph splits by analyzing line heights, and appends a divider line (---) between pages.

The final structured text is saved as a local data blob and downloaded immediately as a .md file in your browser.

100% Browser-Side. All parsing logic is written in local JavaScript. Safe for private agreements, papers, or logs.
