How to Remove Your Name and Hidden Data from a Word Document
When you send a Word file, you're not just sending the text. You're sending your name, the names of everyone who edited it, how long you spent on it, and sometimes comments and deletions you thought were gone. Here's what's in there and how to clear it before you hit send.
What a .docx actually stores about you
A modern Office file (.docx, .xlsx, .pptx) is really a zip archive of XML. Tucked inside are property files that record information you never typed:
- Author and last-modified-by names — usually your real name or the account name on your computer.
- Company name — pulled from your Office installation.
- Total editing time and creation/revision dates — how long you actually spent, and when.
- Revision fingerprints (rsid) — hidden IDs that tie edits together across sessions and can link one document to another you wrote.
- Comments and tracked changes — every note and edit, each stamped with the name of who made it.
Why it matters in practice
Most of the time none of this matters. But it does in a few common situations: sending a résumé that still names your current employer in the company field; submitting a document that's meant to be anonymous (peer review, a tip, a complaint); delivering freelance or agency work where the file's author is "John's MacBook" instead of the client's brand; or sharing a contract where accepted tracked changes still reveal what each side pushed back on. The famous cases of leaked author names in legal and government documents almost always came from exactly this metadata.
Option 1: Word's built-in Document Inspector
Word has a tool for this. In Windows: File → Info → Check for Issues → Inspect Document, then remove what it finds. On Mac it's Review → Protect → Remove Document Information (the menus move between versions). It works, but it only covers the fields Microsoft exposes, it changes the file in place, and it's easy to forget a step. It also does nothing if you're on a device without Word installed.
Option 2: Strip it in your browser with ClientSide
Go to clientside.sh/office and drop the file. It opens the document's XML directly in your browser and:
- Clears the author, last-modified-by, company, and title fields
- Deletes custom properties
- Removes all comments
- Accepts tracked changes (insertions are kept, deletions are dropped)
- Strips the rsid revision fingerprints
Nothing is uploaded — the file is processed on your device and downloaded clean. It works on Word, Excel, and PowerPoint files, which matters because spreadsheets and slide decks carry the same hidden author data and people almost never think to check them.
A note on tracked changes
Accepting tracked changes is the step people most often miss. A document can look final while still carrying a full history of every deleted sentence inside the markup. Anyone who turns "Show Markup" back on sees it all. Whichever method you use, make sure tracked changes are accepted (or rejected) and comments are removed before the file leaves your hands — not just hidden from view.

Frequently asked questions
What personal information does a Word document contain?
A .docx file stores the author and last-modified-by names, your company name, total editing time, creation and revision dates, and a revision fingerprint (rsid). If the document has tracked changes or comments, every edit and note is stored with the name of whoever made it.
Does accepting tracked changes remove them completely?
It removes the visible markup, but the author name in the file's properties and the revision fingerprints often remain. Run the file through a metadata cleaner or Word's Document Inspector afterwards to be sure.
How do I remove metadata from a Word file without uploading it?
Use clientside.sh/office. It opens the .docx, .xlsx, or .pptx in your browser, clears the author and company fields, deletes custom properties, removes comments, accepts tracked changes, and strips revision fingerprints — without sending the file anywhere.
Does removing metadata change how my document looks?
No. It only edits the hidden properties and revision data. The visible text, formatting, images, and layout are untouched.
