About the metadata remover

Files contain more than you see. A Word document remembers who wrote it, which company the licence is registered to and who commented along the way. A photo from a phone stores where and when it was taken. A PDF can contain earlier versions of itself. This tool removes that information before you send the file on — and shows you exactly what was found.

Everything happens in your browser. Your files are not uploaded, not stored and not sent anywhere. The cleaned file keeps the same name and format as the original.

What is removed?
  • PDF: author, title, application, dates, XMP metadata, comments and markups, page thumbnails and earlier versions from incremental saves. Links and form fields are kept.
  • Word, Excel, PowerPoint: author, “last modified by”, company, manager, template path, editing time, custom properties, comments and their authors, thumbnail, printer settings and the folder path Excel remembers. In Word, text formatted as hidden is removed too — it is invisible on screen but still in the file.
  • LibreOffice and OpenOffice: author, application, printer, editing time, custom properties, comments and thumbnail.
  • Images: EXIF (camera, serial number, time taken, GPS), XMP, IPTC, comments and hidden data after the image itself. The colour profile is kept so the colours do not change. iPhone photos in HEIC format are not supported yet — export them as JPG first.
  • Images inside documents: photos placed in Word or LibreOffice are cleaned too — otherwise the GPS location travels along with the document.
The options explained
  • Files: drag in up to 50 files at once, at most 100 MB per file. The file type is determined by its content, not just its extension.
  • Remove metadata: cleans all files marked “Ready”. Each file gets a summary of what was removed and its own “Download” button.
  • Password: if a PDF is locked, the tool asks for the password. The file is decrypted, cleaned and encrypted again with the same password and permissions.
  • Word documents: “Remove hidden text” is on by default and is shown in the summary together with the text itself. “Accept all tracked changes” is off: if you switch it on, deleted text is removed completely and inserted text becomes ordinary text. These options only apply to Word — not Excel, PowerPoint or LibreOffice.
  • Download all as ZIP: appears when more than one file has been cleaned.
  • Dates: creation and modification dates in Office and LibreOffice files are set to a neutral time (1 January 1980). This also applies to the internal dates in the files’ ZIP package.

Examples of cleaning

Contract in Word

The properties show the author “Anne Jensen”, the company “Smith & Co Solicitors” and the template C:\Users\anne\Templates\Contract.dotm. Two comments from a colleague are still in the margin.

After cleaning:No author, company or template — 2 comments removed

Photo from a phone

The EXIF data shows the camera model, the time it was taken and the GPS position 55.67612, 12.56834 — in other words, an address in Copenhagen.

After cleaning:Only pixels and orientation left

PDF saved several times

The file was edited in Acrobat and saved three times. The first two versions — including a paragraph that was later deleted — are still in the file.

After cleaning:One version, no author or XMP

Spreadsheet in Excel

The workbook remembers the folder C:\Users\anne\Documents\Salaries\, the office printer and three cell comments.

After cleaning:Folder path, printer and comments removed
If you are an employer, keep in mind

Names and initials in metadata are personal data. If you send documents out of the organisation — to customers, opposing parties or the public — they travel with the file unless they are removed.

Tracked changes are kept by default, but anonymised — and deleted text is still in the file. If you want it gone, switch on “Accept all tracked changes”, or reject the changes in Word before cleaning. In LibreOffice files this has to be done in the program itself.

If you are an employee, keep in mind

Metadata can reveal who wrote or forwarded a document. Clean files before you share them if the sender must not be traceable.

The tool removes metadata — not content. Names in the text itself, in headers and in images are for you to check. Hidden text in Word is the one exception; hidden worksheets, rows and slides in Excel and PowerPoint stay in place. To black out text in a PDF you can use the PDF anonymisation tool.
