Clean Markdown for your Obsidian vault

Convert PDFs, Word docs and web pages to tidy Markdown with YAML front-matter — private by default, because nothing leaves your machine.

Drop files, paste, or click to browse

PDF, Word, Excel, PowerPoint, HTML, CSV, JSON, EPUB, images and more. Nothing is uploaded.

Obsidian is a local-first tool, and so is MarkPrep — a natural fit. Convert a PDF, DOCX or web page to clean Markdown, get YAML front-matter (title, source, date) ready for your vault, and paste or download straight in. Repeated headers and page numbers are stripped so your notes read like notes, not scanned pages. Your documents never touch a server.

YAML front-matter generated automatically
Repeated headers, footers and page numbers stripped
Works offline as an installable app
Private by architecture — nothing uploaded

Frequently asked questions

Does it add front-matter for Obsidian?+

Yes — turn on YAML front-matter (preset on for this page) and each file gets title, source, page count, word count, token estimate and date.

Can I use it offline?+

Yes. Install it as a PWA and it keeps converting with the Wi-Fi off — just like your vault.

Are my notes private?+

Completely. Conversion runs in your browser; there's no upload endpoint.
