An Obsidian vault is only as useful as what’s actually in it — and for most people, years of notes are trapped in Word files, PDFs, and email attachments. Embedding a PDF in a note doesn’t help: you can’t link to its sections, it doesn’t show up properly in search or graph view, and plugins can’t touch it. The documents need to become real Markdown.
Headings become real Markdown headings, so Obsidian’s outline pane and [[Note#Section]] links work on the imported content. Tables arrive as pipe tables you can edit in place. Scanned documents are OCR’d on-device first — see the scanned PDF guide — so even that box of scanned meeting minutes becomes searchable text.
Milldown can prepend YAML front matter to every converted file — source filename, conversion date, and a SHA-256 hash of the original. In Obsidian these surface as Properties, which means Dataview queries like “everything imported from the contracts folder this year” work out of the box, and you can always trace a note back to the exact source document it came from.
The nicer trick is making import continuous. Create an Inbox folder anywhere outside your vault and set it as a Milldown watch folder. Every document you drop there — or that your scanner or browser drops there — is converted automatically into its Markdown/ subfolder, which you point into your vault (a symlink works, or just watch a folder inside the vault and let the mirror land there). New PDF in, new note out, no app-switching. More patterns in the batch conversion guide.
Why not a web converter? Notes are among the most personal documents there are, and a vault import is exactly the moment you’d otherwise upload hundreds of them to a stranger’s server. Milldown runs entirely on your Mac — conversion, OCR, everything — so the only place your notes exist afterwards is your vault. Details on the security page.
Markdown is a text format: embedded images from Word files and PDFs aren’t carried into the converted note. For image-heavy documents, keep the original file in an Attachments folder and add an embed link in the note — you get searchable text and the visual original, which is usually better than either alone.
