Office metadata remover

Drop a Word, Excel or PowerPoint file and strip its hidden author/company/date properties. Everything stays on your device.

How Office metadata remover works

Office Metadata Remover strips the hidden document properties stored inside Word (DOCX), Excel (XLSX) and PowerPoint (PPTX) files, fields like author name, company, last modified by, revision count, creation date, manager and custom properties set by your organisation's template. These properties travel invisibly with the file and can expose personal or corporate information when you share a document externally.

The tool removes the standard document properties it can reach inside the Open XML structure. It does not remove content embedded in the document body itself (such as tracked changes, comments or speaker notes), and it cannot reach properties stored in proprietary binary sections of some older formats. Review the output to confirm what was cleaned. It works on the modern Open XML formats (DOCX, XLSX, PPTX), not the legacy binary .doc, .xls or .ppt.

Frequently asked questions

Which specific properties are removed?

Standard Office document properties: author (creator), last-modified-by, company, manager, revision number, creation date and time, last-modified date, last-printed date, and custom properties defined in the file. Tracked changes, comments and embedded macros are separate and are not altered by this tool.

Does it work on older .doc, .xls, .ppt formats?

The tool targets the modern Open XML formats (DOCX, XLSX, PPTX). Legacy binary formats (.doc, .xls, .ppt) are not supported. Convert them to the modern format in Word/Excel/PowerPoint first, then clean the metadata here.

Will removing metadata affect the content or formatting of my document?

No. Only the document properties are modified; the text, tables, images, styles and formatting in the document body remain untouched.

Are my files uploaded to a server?

No. Every operation runs inside your browser tab using JavaScript and WebAssembly. Your file is read into memory on your own device, processed there, and the result is offered as a local download. Nothing is transmitted to Sunasty or any third party. You can verify it yourself: open your browser DevTools, go to the Network tab, and watch, no request carries your file.

Does it work offline?

Yes, once the page has loaded. Because the processing happens on your device, you can disconnect from the network and the tool keeps working. This is the clearest proof that your data never leaves your machine.

Is it free? Do I need an account?

It is completely free and requires no sign-up. There are no watermarks, no daily limits and no tracking cookies needed to use the tool.
