How do I edit the metadata of a PDF?
Upload your PDF and the editor reads the existing title, author, subject, keywords, creator and producer fields. Edit any of them in the form, leave fields blank to clear them and save the file. The updated PDF downloads with the new metadata embedded. The actual page content is untouched, so the document looks exactly the same. This is the quickest way to fix wrong author names or set proper titles before sharing a file publicly.
Is the metadata editor private and browser-only?
Yes. The editor uses pdf-lib to read and rewrite the document inside your browser, with no upload involved. That keeps confidential files like contracts, internal reports or invoices private even while you correct their properties. Nothing is logged, no analytics see your content and the file disappears from memory when you close the tab. The privacy guarantee is the same as for the other PDF tools on this site.
What metadata fields can I view and edit?
You can view and edit the standard PDF fields: title, author, subject, keywords, creator and producer. Creation and modification dates are also visible, although they are usually best left to the software. Custom XMP metadata such as copyright statements or document IDs can be inspected too. If a field shows as blank the source PDF simply did not set it, and you are free to add a value before saving the updated file.
Why does my edit not appear in some PDF readers?
Many readers show metadata from the older info dictionary, while others prefer the newer XMP metadata stream. The editor updates both, but a few specialised tools may aggressively cache earlier values. Restart the reader, or open the file in a different one, to confirm the change. If the document was signed or certified, edits to metadata may invalidate the signature, in which case you will need to re-sign after editing.
Can I remove all metadata from a PDF for privacy?
Yes. Clearing every field and saving produces a PDF whose info dictionary and XMP stream contain no identifying information. This is useful before publishing a document publicly, since hidden metadata can otherwise leak the original author, software used or company name. Note that other privacy traces such as embedded comments or hidden layers are not part of metadata, so use a dedicated redaction tool if you also need to scrub annotations or document structure.
Does editing metadata change the PDF page content or size?
No. Metadata lives in a small section of the file that is separate from the pages, so editing it does not touch the visible content. File size changes by only a few hundred bytes. Text remains searchable, images keep their resolution and any signatures, forms or annotations stay intact, although re-saving the file may invalidate certain digital signatures. For pure text and image edits, use the dedicated tools instead.
