About MetaDocu

Every day, millions of business contracts, resumes, and confidential documents are shared online carrying hidden metadata — author names, company details, local file paths, GPS coordinates in embedded images, and revision histories that silently expose private information. MetaDocu was built with a singular conviction: privacy-sensitive document processing should never require uploading your files to anyone's server. We deliver a complete metadata audit and cleaning toolkit that runs entirely inside your browser's WebAssembly sandbox.

MetaDocu uses cutting-edge WebAssembly technology to process documents directly in your browser. When you load a file, it stays in your device's local memory — no network requests, no cloud storage, no server-side processing whatsoever. Our engine reconstructs Office XML trees, recalculates PDF cross-reference tables, strips paragraph-level RSID revision markers, and recursively purges embedded EXIF/GPS data from nested images — all within milliseconds, right on your machine.
