How Metadata Removal Works

Office documents (DOCX, XLSX, PPTX) are ZIP files containing XML. Your document's metadata lives in docProps/core.xml and docProps/app.xml. This tool reads the ZIP, finds and clears personal fields (author, lastModifiedBy, company, etc.), also strips author info from revision marks and comments, then rebuilds the document for download. Everything runs entirely in your browser - no uploads, no servers.

Features

Strip Personal Metadata

Removes author name, last modified by, company name, manager, category, publisher, and revision number from Office documents. Clears creation and modification timestamps for complete privacy.

Multi-Format Support

Supports all Office Open XML formats - DOCX (Word), XLSX (Excel), and PPTX (PowerPoint). Also strips comment author information and revision tracking metadata from the document body XML.

Comment & Revision Cleaning

Beyond document properties, also strips author information from embedded comments, tracked changes, and revision marks within the document body. Removes comment initials and author attribution.

100% Private & Local Processing

All metadata removal runs entirely in your browser using the JSZip library. Your documents are never uploaded to any server - they stay on your device the entire time. Download the cleaned version locally.

Use Cases

Privacy Protection

Before sharing documents externally, strip all personal metadata to prevent exposing author names, company information, and revision history. Essential for legal documents, contracts, and confidential reports.

Client Document Sharing

When sending proposals, invoices, or reports to clients, remove internal metadata that may reveal internal document structure, author names, or editing history that should remain private.

Job Applications & Resumes

Strip metadata from resume and cover letter documents before sending to employers. Remove the author name and editing history to maintain a clean, professional submission.

Internal Document Leak Prevention

When documents are leaked or shared beyond their intended audience, metadata can identify the original author and editor. Regular metadata cleaning reduces attribution risk.

Document Publishing

Before publishing documents online or submitting to public repositories, strip all identifying metadata to maintain anonymity and prevent tracking through document properties.

GDPR & Data Compliance

Remove personal data embedded in Office documents as part of data minimization practices required by GDPR, CCPA, and other privacy regulations. Metadata containing personal information must be removed or anonymized.

About

What Is Document Metadata?

Document metadata is hidden information embedded in Office files (DOCX, XLSX, PPTX) that includes the author name, last person to modify the document, company name, creation and modification dates, revision number, category, and manager name. This metadata is automatically added by Microsoft Office and other productivity applications whenever you create or edit a document.

Why Remove Document Metadata?

When you share Office documents externally, the embedded metadata can reveal personal or confidential information you may not want to disclose - like the names of everyone who edited the document, your company structure, or how many revisions were made. Removing this metadata is a critical privacy practice for legal documents, client proposals, published materials, and any document shared beyond your organization.

Where Is Metadata Stored?

Office Open XML files (DOCX, XLSX, PPTX) are ZIP archives containing XML files. Personal metadata is primarily stored in docProps/core.xml (creator, lastModifiedBy, revision) and docProps/app.xml (Company, Manager). Additional author information may appear in comments (word/comments.xml) and revision marks within the document body XML. This tool finds and clears metadata from all these locations.

Browser-Based Processing & Privacy

All metadata removal runs entirely in your browser using the JSZip library. Your documents are never uploaded to any server - they stay on your device. The tool reads the ZIP structure, parses the XML metadata files, clears personal fields, rebuilds the ZIP, and offers the cleaned document for download. No data is logged, stored, or transmitted anywhere.

FAQ

What metadata fields does this tool remove?

The tool removes: author (dc:creator), last modified by (cp:lastModifiedBy), revision number (cp:revision), category (cp:category), publisher (dc:publisher), company name (extended:Company), manager name (extended:Manager), and creation/modification timestamps (dcterms:created, dcterms:modified). It also strips author information from embedded comments and revision marks within the document body.

Which Office document formats are supported?

The tool supports DOCX (Word), XLSX (Excel), and PPTX (PowerPoint) files. These are the modern Office Open XML formats. Legacy binary formats like DOC, XLS, and PPT are not supported because they use a completely different file structure (OLE2) that cannot be processed in the browser.

Does this tool also remove content from the document?

No, the tool only removes metadata - it does not modify any document content, formatting, images, or data. Only the hidden personal information stored in the document properties and XML metadata files is cleared. The document's appearance and content remain completely unchanged.

Is the cleaned document still a valid Office file?

Yes. The tool preserves the complete ZIP structure of the document and only modifies the metadata XML files. The cleaned document opens normally in Microsoft Office, Google Docs, LibreOffice, and any other application that supports Office Open XML formats.

Can I remove metadata from multiple files at once?

Currently, the tool processes one file at a time. For batch processing, you can use the tool repeatedly for each document. All processing is instant - typically under a second for most documents.

Are my documents uploaded to any server?

No. All processing runs entirely in your browser using the JSZip library. Your documents are never uploaded to any server - they stay on your device from start to finish. You download the cleaned version directly from your browser.

Will the file size change after metadata removal?

Yes, typically the cleaned file will be slightly smaller (by a few hundred bytes to a few kilobytes) because the metadata field contents are cleared. The reduction is negligible and does not affect document quality or functionality.

What if my document has no metadata to remove?

Some documents may have minimal or no metadata if they were created by applications that don't add personal information. The tool will report that no metadata was found and still provide a cleaned copy of the document for download.

Is this Document Metadata Remover completely free?

Yes - 100% free, forever. No signup, no account, no premium tier, no usage limits. Clean as many documents as you need. All processing is done locally in your browser with zero server uploads.
