Turn any document into clean, AI-ready Markdown. Runs on your machine, nothing uploaded, and it reads the scanned PDFs other tools miss.
This is the first public build of MDFlux, a portable Windows app built on Microsoft's MarkItDown.
What it does
- Converts PDF, DOCX, PPTX, XLSX, EPUB, HTML, CSV, JSON, XML, images, and audio into clean Markdown.
- Reads scanned, image-only PDFs with built-in OCR (plain text extractors return zero characters on these).
- Uses up to 6 times fewer tokens than feeding pages to a vision model, so every downstream LLM call costs less.
- Runs fully offline after a one-time first-run setup. No API key, no account, nothing uploaded.
- Batch-converts a whole folder with progress, cancellation, and per-file diagnostics.
- Optional cleanup: off, rule-based, or a local AI pass.
Install
- Download
MDFlux_0.1.0_portable.zipbelow. - Extract it anywhere (for example
C:\Apps\MDFlux\). - Run
MDFlux.exe.
This is a portable app, so there is no installer. The first launch sets up a private, self-contained Python environment (one time, needs internet). After that it runs offline.
Notes for the first run
- Windows SmartScreen may show a one-time "Windows protected your PC" message. The build is open source and unsigned, so click "More info" then "Run anyway". Code signing is on the roadmap.
