What markitdown is
markitdown is a browser based converter that turns PDF, Word and similar documents into Markdown. The idea traces back to an open source tool originally released by Microsoft, and this site runs as an independent online service inspired by it, so nothing needs to be installed on your machine. Format specific parsers handle the input and try to keep headings, lists and tables intact rather than dumping raw text into a single block. The free tier processes up to 3 files per batch, each capped at 20MB, and it does not ask you to register. Paid tiers raise the file size and batch limits and add unlimited storage of results. It is a utility built for one job: getting document text into a clean, structured form that other tools can read.
What you can do with it
- Convert PDF and Word files into Markdown with headings and lists preserved
- Process a small batch of documents at once without creating an account
- Feed cleaner text into AI assistants, note taking apps or a knowledge base
- Keep results for later reuse if you move to a paid tier
Who it is for
- Writers and researchers who keep their notes in Markdown
- Developers preparing document context for language models
- Teams migrating scattered PDFs into one searchable knowledge base
What to watch out for
The free limits are real. Three files per batch and 20MB per file will not cover a large document dump, and anyone working through a backlog will end up on the professional tier. Conversion quality depends on the source: scanned PDFs, unusual fonts, multi column layouts and complex tables can still come out messy, so plan on reviewing the output before you rely on it. Because this is an independent service inspired by an open source project rather than the project itself, the feature set and the free rules can change over time. Treat the free tier as a way to test the workflow, not as a permanent guarantee.
