What is PDF to Markdown Converter?
PDF to Markdown Converter is a browser-based tool that reads embedded text from a PDF file and converts it to Markdown format using heuristic analysis. It uses PDF.js to process the file entirely on your device —no file is ever sent to a server. Font size comparisons are used to detect headings (H1, H2), and common list patterns are automatically converted to Markdown bullet points or numbered lists.
How to Use PDF to Markdown
- Drop a PDF file onto the upload area or click to browse and select one.
- Wait for conversion to complete —a progress bar shows the current page.
- Review the Markdown output in the "Markdown Source" tab.
- Switch to the "Preview" tab to see a rendered HTML preview of the Markdown.
- Click "Copy Markdown" to copy to clipboard, or "Download .md" to save as a file.

Frequently Asked Questions
No. The entire conversion runs inside your browser using PDF.js. Your file never leaves your device and no data is sent to any server.
Heading detection is heuristic-based: it compares each line's font size to the median font size on the page. Lines that are significantly larger are promoted to H1 or H2 headings. This works well for PDFs with clear visual hierarchy but may misclassify decorative large text or footers.
No. This tool converts embedded text from PDFs. Scanned PDFs are images of text and contain no embedded text data. You would need OCR software to first extract text from scanned documents before converting to Markdown.
This tool works best on text-heavy PDFs such as reports, documentation, articles, and e-books with consistent heading styles. The output is ideal for pasting into Markdown editors, static site generators, note-taking apps like Obsidian or Notion, or version-controlled documentation repositories.
