Frequently Asked Questions
How does PDF to Markdown conversion work?
Upload your PDF file. The tool uses pdf.js to extract text from each page, detects headings by font size, and formats the output as Markdown. The .md file downloads directly to your device.
Do you upload my PDF?
No. All conversion happens in your browser. Your PDF file is read locally using File API and never sent to any server.
Are headings detected automatically?
Yes. The tool analyzes font sizes from the PDF text layer. Larger fonts are mapped to Markdown headings (# for h1, ## for h2, ### for h3). Body text becomes paragraphs.
What Markdown features are generated?
Headings (#, ##, ###), paragraphs, bullet lists (-), and bold text. Tables and images from the PDF are not preserved in the Markdown output.
Is there a file size limit?
No hard limit. Very large PDFs may take longer to process. The tool runs entirely in your browser.
Can I convert scanned PDFs?
Scanned PDFs without a text layer cannot be converted. The tool requires a PDF with selectable text. Use OCR tools first for scanned documents.
