Document metadata remover.
Clean DOCX, XLSX, PPTX, ODT, ODS, and ODP — author, properties, comments, tracked changes, all gone.
This is the document variant — a free, browser-based alternative to Microsoft Office's Document Inspector that also handles Excel, PowerPoint, and OpenDocument files. Drop a file, get a clean copy. The author, company, edit history, and custom properties are wiped; the document content itself is unchanged.

What this document metadata cleaner removes
Office and OpenDocument files are ZIP archives containing XML. The metadata lives in three predictable places: the core properties (author, last-modified-by, dates, title), the application properties (total edit time, application name, company), and any custom properties added by templates or add-ins. This tool removes all three. Whether you need to remove the author from a Word document, clean DOCX metadata, scrub Excel metadata, sanitize a PowerPoint presentation, or clear OpenDocument properties — same tool, same outcome. Tracked changes and comments are stripped on request as a separate option.
View mode shows every property without modifying the file — useful as a Word document properties viewer or Excel properties inspector.
Privacy-first by design
Why this metadata remover is different.
Most online metadata cleaners upload your files to a server. We don't.
Files never leave your browser
Every byte stays on your device. The metadata stripping runs locally in WebAssembly and JavaScript — there is no server-side processing. Open your network tab and check while it works.
Free, no signup, no watermark
Use it once or use it daily. There's no account to create, no email to confirm, no "upgrade" pop-up. We built this metadata removal tool because we needed it ourselves.
Strip and inspect — same tool
Switch to view mode to see exactly what's hidden in your files before deciding to remove it. Doubles as a free EXIF viewer, PDF properties viewer, and document inspector.
Built on audited open primitives
Powered by piexifjs (image EXIF), pdf-lib (PDF), fflate (Office and OpenDocument files), and mp4box (video). All open-source, all client-side, all running in the page you're reading.
What gets removed
The hidden data in your files.
Most files carry hidden information you never see — but the recipient does.
Documents
- Author and last-modified-by names
- Company and organization
- Total editing time
- Revision number and history
- Custom document properties
- Comments and tracked changes
- Hyperlink and template references
When document properties leak
Templates with someone else's name
Internal templates often carry the original author. Remove the author from a Word document before client delivery.
Resume and CV submissions
Employers see your full edit history. Document properties cleaner clears it before sending.
Excel models shared externally
XLSX metadata leaks the original modeler's name and total editing time. Strip XLSX metadata before sharing.
Anonymous editorial submissions
Academic blind review depends on the author field being empty — this clears it correctly.
How it works
Three steps. No upload.
1. Pick your file
Choose a photo, PDF, video, or document. The metadata remover loads only the engine for that file type — keeping the page fast for everyone else.
2. Strip locally
Your browser parses the file and removes the hidden metadata in memory. We never see the file. We never see the metadata. There is no upload.
3. Download cleaned
Save the cleaned file back to your device. Optionally download a JSON of what was removed, so you have a record.
By file type
Specialized tools for each format.
Or jump straight to the right one:

Common questions about metadata removal.
Functionally similar — both clear core properties, custom properties, comments, and tracked changes. The differences: this is free, runs in any browser, doesn't require Office to be installed, and works on Mac, Linux, and ChromeOS. The cleaning happens to the raw OOXML, so the result is byte-stable.
From the team behind Vaulternal
Want this same privacy for the files you can't always reach yourself?
You just cleaned this file without ever uploading it. Vaulternal applies the same zero-knowledge approach to conditional access continuity — encrypted files that reach a trusted person only when conditions you set in advance are met. Long trips, hospital stays, planned handovers. No servers in the loop, ever.
