Metadata Privacy Cleaning Solutions
For common document formats shared and submitted online, MetaDocu provides professional browser-local metadata sanitization solutions, targeting key sensitive properties and rebuilding file binary structures safely.
Word / Excel / PPT Purging
Instantly scan and strip creator, manager, company name, and last modified by. Clean random revision histories (RSID) embedded within paragraphs, and recursively strip camera EXIF data from nested media images.
PDF Signature & Xref Rebuild
Scan PDF files to detect digital signatures (warning triggered) to prevent file hash corruption. Gracefully capture password-protected PDFs for local decryption, and physically rebuild the PDF layout with Xref recalculation.
EXIF & GPS Photo Stripper
Scan and physically wipe camera metadata, capture timestamp, and geographic GPS coordinates from JPEG/PNG images. Retain perfect image resolution while removing all metadata footprints.
Frequently Asked Questions
Are my files uploaded to your server?
Absolutely not. MetaDocu is 100% browser-local. The metadata scanning and cleaning processes run entirely within your local WebAssembly sandbox. Your files never leave your device.
What metadata privacy risks can this tool detect?
It deeply parses and strips over 20 sensitive items, including creator name, last modified by, creation/modification times, local development template absolute paths, software versions, paragraph RSIDs, and image GPS locations.
How do I check PDF metadata without uploading?
Simply drag and drop your PDF into the upload zone. The local WebAssembly engine parses the document's Info dictionary in browser memory, listing all properties on your screen with zero network transfer.
Can Word documents reveal comments or revision history?
Yes. Word documents record random paragraph RSID markers that trace revision histories and editor footprints. MetaDocu purges these internal XML nodes cleanly, restoring privacy.
Is local metadata scanning safer?
Yes. Traditional online metadata utilities require uploading contracts, resumes, or financial spreadsheets to their servers, inviting leakages. MetaDocu performs a strict client-side sandbox cleanup, locking down your data.
Can images contain GPS metadata?
Yes. Smart phones and digital cameras record capture parameters and GPS locations into EXIF segments. MetaDocu performs a physical byte-strip of EXIF chunks, outputting clean images.
How do I remove metadata from a Word document before sharing?
Open MetaDocu's Word tool, drop in your .docx or .doc file, and it lists the hidden metadata — author, company, edit history and tracked changes. Click Clear to remove it, then download the sanitized copy. Everything runs locally in your browser, so the file is never uploaded.
