    How to use

    1. 1. Add PDFsDrop them on the box or click to choose. Add up to 20 at once. You'll see the author, title, software, dates and other information inside each one.
    2. 2. RemovePress “Remove hidden info”. The result is read again to check that nothing is left.
    3. 3. SaveSave each PDF, or press “Save all”. File names get “_clean” added.

    You can also remove it in Word or Excel

    Word, Excel and other Microsoft 365 apps have a Document Inspector that removes the author and other information (File → Info → Check for Issues → Inspect Document). If you remove it before making the PDF, it won't be in the PDF either. When you only have the PDF, or you're passing on a PDF you received, you can remove it here.

    Hidden information a PDF can contain

    • Author and company name
    • Title (sometimes an internal file name), subject, keywords
    • The software that made it and the software that turned it into a PDF
    • Created and modified dates
    • XMP (a second copy of the author and other details)
    • Names of people who wrote comments
    • Earlier author names and titles left by incremental saves

    FAQ

    Who is this for?

    Anyone sending quotes, reports or other PDFs outside their company who wants to remove the creator's name or internal file names first. Anyone who made a PDF from someone else's template and wants to check that person's name isn't left inside.

    What information is inside a PDF?

    The author name, title, subject, keywords, the software that made it, the software that turned it into a PDF, and the dates it was created and changed. PDFs made in Word and similar apps can include the name of the computer account as the author. The title can be an internal file name.

    How do I clean PDF metadata?

    Drop up to 20 PDFs on the box to see the author, title, software, dates and other information inside. Press “Remove hidden info”; the result is read again to check that nothing is left. Then save each PDF or press “Save all”.

    What is “old information left by saves”?

    A PDF can be saved by adding changes to the end of the file instead of rewriting it. Then, even if the author was changed, the earlier author name can still be inside the file. This page drops old data that nothing uses any more and saves the file again, so old names are removed too.

    Does the PDF look different afterwards?

    No. The text and images on the pages are not re-made; only the hidden information is taken out.

    What happens to comments?

    The comments themselves stay. Only the name of the person who wrote them and the date are removed.
