Know what this tool changes
A PDF can store information about its title, author, subject, keywords and the software that created it. That information may be visible in a reader's document properties even when it is not printed on the page.
Pageivo Remove Metadata clears these common information fields and resets the creation and modification dates to the Unix epoch. It saves a new copy. It does not inspect every possible hidden object, redact visible content or promise that a document is anonymous.
Inspect the synthetic example before cleaning
The Lab source deliberately contains the author 'Pageivo sample author', a title and software information. It also has the visible sentence 'Visible sample author: Pageivo - this text is not metadata.' That sentence is useful because it should remain after cleanup.
Download metadata-source.pdf and open its document properties in a reader that exposes them. Record the common fields, then compare them with the cleaned reference. A browser's basic PDF preview may not show every property.
| Information | Pageivo's output |
|---|---|
| Title, Author, Subject, Keywords | Cleared |
| Creator and Producer | Cleared |
| Creation and modification dates | Reset to 1970-01-01; a reader may display this in its local time zone |
| Visible names and text | Remain on the page |
| XMP, attachments, comments, form values, hidden layers | Not comprehensively removed by this tool |
Run the cleanup and verify it
- Open Remove Metadata and choose Try a sample, or select metadata-source.pdf manually.
- Choose Remove Metadata and download the new -clean.pdf file.
- Open the cleaned file's properties and confirm that the common fields are blank or reset.
- Inspect the page itself. The visible sample-author sentence should still be there.
- Check the downloaded filename separately. A filename can expose information even when PDF properties are blank.
Use the right workflow for hidden and visible information
If you need to remove a name printed on the page, metadata cleanup cannot do it. Covering text with a white rectangle or a watermark is also not a reliable redaction workflow. Use a dedicated redaction tool and verify the result.
PDFs may contain attachments, comments, form data, hidden layers or XMP metadata. A complete sanitization workflow needs to inspect these structures. Adobe's sanitization documentation linked below describes a broader class of operation than Pageivo's common-field cleanup. Choose that kind of tool when you need comprehensive removal.
Why properties can appear to return
Check that you reopened the cleaned download rather than the original. Some applications populate new producer or modification details when they save a PDF again. The final copy to be shared is therefore the one whose properties you should inspect.
A reader can also show a filename as the window title when the internal Title field is empty. That does not necessarily mean the internal metadata remained. Use the properties view to distinguish a file label from the stored title.
Keep useful originals and share a reviewed copy
Metadata can be valuable for provenance and internal document management. Retain the original privately if you need those details, then create a separate sharing copy.
Review the visible pages, properties, filename and recipient together. Removing common metadata reduces one source of accidental disclosure; it does not replace checking what the document actually says or where it will be sent.
Try the worked example
Compare the document properties before and after cleanup. A visible sample-author sentence stays on the page.
Try it: Choose Remove Metadata, download the result and inspect its document properties.
