Every Office file is a zip of XML parts, and several of them are about you rather than your content: who created it, who last saved it, your company name, how long it was open, and an ID for every editing session. StripShot rewrites the package in your browser and drops those parts. The text, formatting and images stay as they are.
Last updated September 2026
Drop the .docx, .xlsx or .pptx below. StripShot lists what it found (author, last modified by, application, company, editing time, revision session IDs, comments, hidden characters), rewrites the file without them, and re-scans the result. Nothing is uploaded.

Free: unlimited scans and a few strips a day. Pro: unlimited, plus whole folders at once.
Rename a Word file to .zip and open it, and this is what you find. Most of it is content. The rest is a record of who made the document and how.
| Part | What it holds | Removed |
|---|---|---|
| docProps/core.xml | Author, last modified by, title, subject, keywords, revision count, created and modified dates, last printed | Yes |
| docProps/app.xml | Application and version, company, template name, total editing time, page and word counts | Yes |
| docProps/custom.xml | Arbitrary key and value tags added by add-ins or document management systems | Yes |
| docProps/thumbnail.* | A preview image of the first page | Yes |
| word/comments*.xml, word/people.xml | Comment text plus the name of every person who commented | Yes |
| customXml/ | SharePoint and content-type tagging | Yes |
| w:rsid attributes | A random ID per editing session, stamped on paragraphs and runs, listed again in settings.xml | Yes |
| Invisible characters | Zero-width spaces, directional marks, soft hyphens and other format characters inside the text | Yes, except the few a word needs, which are listed as kept |
| Look-alike letters | Letters from another alphabet standing in for Latin ones, such as a Cyrillic а in an English word | Replaced |
| word/document.xml, styles, numbering, headers, footers, media | Your actual content | Kept |
Tracked changes stay in the document, deleted text included. Accept or reject them in Word before you strip.
Word generates a new rsid (revision save ID) every time a document is opened and edited, and stamps it on the text written in that session. Two documents that share rsid values share an ancestor: the same template, the same draft, the same author machine. Document Inspector does not touch them. StripShot removes every rsid attribute from the body and the rsid list from settings.xml, so the clean file carries no editing lineage.
Workbooks and decks use the same docProps parts, so the author, company and editing time come out the same way. In a .xlsx, StripShot also cleans hidden characters out of the cell text. In a .pptx it cleans every slide, speaker note, layout and master. In a workbook or a deck, comments keep their text but lose the names and dates. Photos, SVG pictures, videos, sound clips, chart data and embedded documents are cleaned too. A picture or file the tool cannot clean is named in the scan.
Drop the file
Drag a .docx, .xlsx or .pptx into the tool above, or click to choose it. It is scanned in your browser.
Read the scan
StripShot lists the author, last-modified-by name, application, company, editing time, comments, session IDs, and any invisible characters or look-alike letters in the text.
Strip
Click Strip. The package is rewritten without the property parts, comment parts and rsid stamps. Body text keeps its words, punctuation and spacing.
Download and re-check
The tool re-scans the output and strikes through everything that is gone. Download the clean copy and send it.
A .docx is a zip of XML parts. docProps/core.xml holds the author, who last saved it, title, revision count and timestamps. docProps/app.xml holds the application, company name, template and total editing time. Comments and tracked changes carry reviewer names, and every paragraph carries rsid session IDs that fingerprint the editing history. The body text can also contain invisible Unicode characters pasted in from elsewhere.
No. Formatting, styles, headers, footers and the pixels of every picture stay exactly as they were. The file opens normally in Word, Google Docs, LibreOffice and Pages.
Comments are removed together with the reviewer names in people.xml. Tracked changes stay in the document, but each name is replaced with a neutral one and each date is removed or reset.
Document Inspector removes the properties it knows about, but it leaves the rsid session IDs stamped on every paragraph, and it does not look for invisible characters in the text. Both can identify a document or its origin.
No. The zip is unpacked, rewritten and repacked inside your browser tab. Close the tab and it is gone. StripShot has no server route that receives file bytes.
Yes. .xlsx and .pptx share the same docProps parts. StripShot also cleans hidden characters out of the cell text in a workbook and out of every slide and speaker note in a presentation.
The old binary .doc format is not supported; open it in Word and save as .docx first. For Google Docs, use File, Download, Microsoft Word (.docx), then clean the download.
Author, Producer, XMP stream and document IDs.
Zero-width and hidden Unicode in any text.
Every format on one page, batch and zip download.
