About Hack the Hydra

Hack the Hydra (hackthehydra.com, formerly DocMD) builds small, free tools that turn documents into clean Markdown and text, the format AI assistants and search pipelines work best with: PDF, scanned PDF (OCR), Word, PowerPoint, Excel, CSV, JSON, HTML and images.

Private by design

Every converter on this site runs in your browser. Your files never leave your device, so you can use them on confidential documents.

Open source

The converters are open source under the MIT license: github.com/extascorp-afk/document-tools.

For developers

The same engines are available as pay-per-use APIs for bulk conversion, with table detection and OCR for scanned PDFs: Apify and RapidAPI.

Videos

We also make short videos of satisfying algorithms and simulations: YouTube, Instagram and TikTok.
