Need to check several kinds of files at once? Use Metadata Check
Open a .docx, .xlsx or .pptx and see what it carries besides the content you wrote — author names, tracked changes, hidden sheets, cropped originals — then clear the metadata, all in this tab.
Your files never leave your browser — all processing is local.

Need to check several kinds of files at once? Use Metadata Check
A Word document, an Excel workbook or a PowerPoint deck is a ZIP of XML parts, and the parts you never see on screen carry more than most people expect: who wrote it and who edited it last, the company and manager fields, the template it started from, total editing time, custom properties, a saved thumbnail of the first page, and a people list naming everyone who ever commented — often with their email address. This page opens .docx, .xlsx and .pptx files, plus the macro-enabled .docm, .xlsm, .pptm and the template variants, reads those parts in your browser, and lists what it found. The file is never uploaded.
Word: tracked changes including the deleted original wording, comments, hidden text, rsid revision markers, the attached template path, and text that is possibly white-on-white or tiny — reported as a heuristic, never as a certainty. Excel: the absPath of the folder the workbook was last saved in, hidden and very-hidden sheets, hidden rows and columns, links to external workbooks, pivot caches that still hold rows deleted from the source sheet, and hidden defined names. PowerPoint: cropped pictures whose full original is still inside the file (the page shows the original with the visible area outlined), hidden slides, speaker notes, objects dragged off the canvas, and embedded fonts. All three: external links pointing at local paths such as C:\Users\name\... or \\server\share, embedded workbooks behind charts (inspected one level down), OLE embedded files that may carry their source path, macros, and orphaned images that nothing references.
Cleaning is deliberately narrow. It empties the document property fields, clears extended properties such as company and manager while keeping the application name and version, removes custom properties and the saved thumbnail, and clears Excel's absPath. Optionally it anonymizes authors: the same person becomes the same Author 1 or Author 2 everywhere, so a revision history still shows whether two edits came from one hand — but names mentioned inside the text of a comment or a revision are not touched. Every other ZIP entry is copied byte for byte. The original file is not modified; the result is saved as <name>-cleaned.<ext>, inspected again automatically, and shown next to the original so you can compare. Tracked changes, comment text, hidden sheets, cropped images and speaker notes are content rather than metadata, so they are not removed here — the report names the Word, Excel or PowerPoint menu that handles each one.
The report never says a file is safe or clean. It says which items it found, which types it checked and found nothing of, and “could not determine” when a part failed to parse — because a missing finding is only as good as the check that looked for it. Windows Office has a built-in Document Inspector under File → Info; this page runs in any browser, needs no Office installed, and is just as useful for a file someone else sent you as for one you are about to send. Not supported: the legacy .doc, .xls and .ppt formats, password-protected files, ODF such as .odt, analysis of macro code, EXIF inside embedded photos (use the Remove EXIF tool for those), and embedded objects nested more than one level deep.
No. The file is opened with the File API, unzipped and parsed in this tab, and the cleaned copy is a download your browser builds from memory. There is no API behind this page, so there is nowhere to send it even by accident. That matters most for exactly the files people want to inspect — contracts, offers, board decks, anything with a name in it.
Open the file here, run the inspection, then clean. The author, last-modified-by, company, manager, template and custom property fields are emptied, and the thumbnail is dropped. If the document has tracked changes or comments, turn on author anonymization as well, so each person becomes Author 1, Author 2 and so on in the revision history. Names written inside the text of a comment or a revision stay, because changing them would change the document's content. The cleaned file is inspected again before you download it, and the before-and-after lists sit side by side.
Yes. Word stores every insertion and deletion in the document XML, so the report lists them with the author, the date, and the deleted original text — the text a reader with Word would find under Review → All Markup. The same goes for comments and hidden text. This page shows them; it does not accept or remove them. To finalize a document, open it in Word and use Review → Accept → Accept All Changes, then delete the comments, and inspect the result here again.
When you crop a picture in PowerPoint, the full original stays in the file and only the visible rectangle changes. The report shows the original with the visible area outlined, so you see exactly what a recipient could recover. To actually remove the cropped-away pixels, open the deck in PowerPoint and use Picture Format → Compress Pictures → Delete cropped areas of pictures, then inspect it here again. This tool does not alter pictures itself.
Yes to both. Excel records the full folder path the workbook was last saved in as absPath, which often includes a user name or a company server; the cleaner clears it. Hidden and very-hidden sheets, hidden rows and columns, hidden names and pivot caches are listed but not removed, because they are content: unhide and delete them in Excel, or use File → Info → Inspect Document on Windows. Whatever you use, drop the result back here — the report only ever says what it found and what it checked, never that a file is clean.
The same check for PDFs: author, producer and dates, then strip them.
Pictures inside a document keep their own EXIF and GPS. Clean the originals here.
