Every feature, individually
The homepage shows six capability groups; this page shows everything inside them. How each one works in practice — settings, shortcuts, edge cases — is in the user guide.
Convert anything
Convert anything
PDF, Word, PowerPoint, Excel, HTML, CSV, JSON, XML, EPUB, ZIP archives, Jupyter notebooks, Outlook messages, and images — powered by Microsoft's open-source MarkItDown engine.
Web pages & YouTube
Paste a URL and get a clean article — Wikipedia formatting, or a YouTube video's full transcript with its title, description and metadata.
Whole folder trees
Drop a folder and get a Markdown mirror of its entire structure — subfolders preserved, ready to commit or index.
Damaged files caught
A corrupt or truncated Office file is refused with an explanation rather than converted into noise.
Private OCR
Scanned PDFs
No embedded text? Milldown recognizes it with Apple’s Vision framework,with the Windows OCR engine, entirely on-device.
Images
JPEG and PNG images get the same treatment — text in a screenshot or a photographed page is recognized on-device, and an image with no readable text is refused with an explanation.
Clean & edit
Clean Up
Strips repeated page headers, footers, page numbers and invisible characters, and tells you exactly how much it removed. Never touches code blocks. One click, fully revertible.
Editable output
Trim the junk before you paste — token counts recompute live as you type.
Session restore
Quit and reopen — your file list and converted Markdown come back exactly as you left them. No re-converting, no re-OCR.
Cancel anytime
Stop a long batch mid-run with one click. Progress shows exactly how many files are done.
Measure what it costs
Token savings counter
Shows an estimated token count and saving for every file, measured against the raw path it would otherwise take to a model — and stays silent where there's no saving to claim. On a monthly plan, read it as headroom against your usage allowance.
Spreadsheets as CSV
Convert .xlsx to plain CSV instead of Markdown tables — 12–29% fewer tokens for the same sheet data. One toggle.
Package for AI
Context Packs
Merge a folder's worth of documents into one paste-able Markdown file with a table of contents.
RAG chunk export
Split by headings into 512–2,048-token chunks — numbered Markdown files or a single JSONL, ready for your vector store.
YAML front matter
Provenance headers (source, timestamp, SHA-256) for archives and pipelines, or Hugo/Jekyll headers for publishing.
Automate everywhere
Command-line tool
Install the milldown command and script conversions in the terminal, CI, or anywhere else — same engine, full option parity.The installer puts the milldown command on your PATH — script conversions in the terminal, CI, or anywhere else, same engine.
Watch folders
Drop files in a folder; a Markdown mirror appears automatically. Set it once, forget it.
Menu-barTray convert & copy
Drop a file on the menu-bar icontray drop window — the Markdown lands on your clipboard, ready to paste into any AI chat.
FinderExplorer integration

Automation
milldown:// URL scheme works from Shortcuts, scripts, and launchersscripts and launchers, with a confirmation step so nothing converts behind your back.
Drag straight out
Drag any converted file from Milldown onto your Desktop or into Claude or ChatGPT — it arrives as a real .md file.
Terminal, ready to go
Open a shell with milldown already on its PATH, without installing anything system-wide.
