Is my PDF uploaded to a server?

No. Everything runs inside your browser using PDF.js. Your file is never sent to any server, making this safe for sensitive documents.

How accurate is the heading detection?

Heading detection uses text-based heuristics: ALL-CAPS short lines become H2 headings and short standalone lines followed by longer text become H1 headings. Complex layouts may need manual cleanup.

Why is some text missing or out of order?

PDFs that consist of scanned images rather than embedded text cannot be converted without OCR. Multi-column or complex layouts may also have text extracted in a non-visual order.

Does it handle password-protected PDFs?

Yes. If your PDF has a user password you will be prompted to enter it. Conversion proceeds locally once the PDF is unlocked.

What Markdown flavor is used?

The output uses standard CommonMark syntax: # and ## for headings, - for unordered lists, 1. for ordered lists, and --- for horizontal rules between pages.

Is there a file size limit?

There is no hard limit imposed by this tool. Very large PDFs may take a few extra seconds because all processing runs in the browser.
