FAQ and format details
Why convert PDF to Markdown?

Literature notes, meeting packets, and 'download this whitepaper' files. You want something Obsidian can search. PDF→Markdown is that dump, with honest quality: a start, not a perfect reconstruction of heading styles.

How this conversion runs

pdf.js → inferred HTML (headings, emphasis, lists, columns) → Turndown. Tables in the PDF are almost never real tables in the Markdown.

Keep in mind for PDF → Markdown

You may still spend time deleting a missed running header or fixing a heading that was just large body type. Figures become nothing. Academic papers with formulas will look like mojibake or missing glyphs.

After you have a Markdown file

Clean the .md: check titles, lists, and column order. Then it behaves like any Markdown file here. Keep the PDF as the citable original.

Do PDF bookmarks become Markdown headings?

Not yet. We use the text layer, not the outline dictionary. Copy the outline from Acrobat if you need a TOC.

Can I convert a scanned book?

Only after OCR produces a text layer. Otherwise the Markdown will be empty or nearly empty.

About PDF and Markdown

Source file

PDF

A page-description format that paints glyphs and graphics onto fixed pages. Universal for print, archival, and sharing.

PDF (Portable Document Format) describes pages, not a flowing document tree. Incoming PDFs are reconstructed as HTML: designed pages keep positioned text, fonts, images, and vectors; simpler reading documents become flowing articles. Export to PDF paints HTML onto pages via pdf-lib. Pixel-perfect Word/InDesign layout is not the goal.

Read into HTML
medium fidelity · implemented — pdf.js extracts text, fonts, images, and vectors. Designed or overlapping pages stay visually positioned; simpler reading documents become flowing HTML with inferred headings, lists, and a sidebar when one exists. Scanned PDFs without a text layer will be empty.

Destination file

Markdown

A lightweight plain-text syntax for structured writing that compiles to HTML. The lingua franca of README files, wikis, and note apps.

Markdown stores documents as readable plain text with a small set of punctuation conventions for headings, emphasis, lists, links, and code. GitHub-Flavored Markdown (GFM) adds tables, strikethrough, task lists, and fenced code blocks. Conversion through HTML is a natural fit because Markdown was designed as an HTML shorthand.
