How to remove metadata from a PDF file
Upload the file to the tool at the top of this page, choose Remove all metadata, then download the cleaned copy. The document is rebuilt from its page content, so the original title, author, subject, keywords, creator, producer and timestamps are gone rather than hidden, and the XMP packet goes with them.
How do I remove properties and personal information from a PDF?
The Windows right click route that works on Office files is unreliable on PDFs: the dialog opens, but the Apply button is often greyed out and the fields survive. Use a tool that rebuilds the PDF instead, either the uploader above, Acrobat Pro with Sanitize document, or a command line utility such as exiftool.
How do I remove metadata from a PDF in Adobe Acrobat?
In Acrobat Pro, open All tools, choose Redact a PDF, then Sanitize document and Remove all. That clears metadata along with scripts, attachments, hidden layers and stored form data. Remove hidden information is the selective version of the same feature. Neither one exists in the free Reader.
How do I remove metadata from a PDF on a Mac?
macOS has no built in way to do it. The Preview inspector shows metadata but will not edit it, and the Print then Save as PDF workaround is unreliable because Quartz copies most of the original fields into the new file. Use the uploader above, exiftool through Homebrew, or Acrobat Pro.
Does removing metadata change the content of the PDF?
No. The pages, the layout and the selectable text stay as they were, which we verified against files from 1 to 276 pages. What changes is the file structure: the document is written out fresh, so the file size moves in either direction and the internal object numbering is different.
Can removed PDF metadata be recovered?
Not from a file this tool has rewritten. Because the document is rebuilt rather than patched, the old Info dictionary and XMP packet are never carried into the new file, so there are no orphaned bytes to recover. Tools that only append a change leave the previous values readable in the file.
What is the difference between removing metadata and redacting a PDF?
Removing metadata clears the hidden fields that describe the document, such as the author name and the software that made it. Redaction removes information from the visible page itself. If a name appears in the body text of the document, stripping metadata will not touch it and you need redaction.
How do I change the author of a PDF?
Switch the tool above to Edit the fields, type the name you want in the Author box, and download the result. The original author value is destroyed in the rewrite rather than left behind it, which is the difference between editing metadata properly and simply typing over it in a viewer.
Can I remove metadata from several PDFs at once?
Not on this page, which handles one file per run. For a folder of documents, exiftool with the all equals nothing switch will clear an entire directory in a single command, and Acrobat Pro can run Sanitize document as an Action across a batch. Both are the right tool once you are past a few dozen files.
Does removing metadata make a PDF anonymous?
It removes one large source of identifying information, not all of them. Text in the document body, a signature image, tracked changes carried over from a word processor, and embedded fonts licensed to a named organization can all identify a source. Treat metadata removal as one step of several, not as the whole job.
