Remove PDF metadata in your browser
PDFs quietly carry metadata — author name, the software that made them, creation and modification dates. LocalSign lets you view, edit, or clear those standard fields in your browser, so you can tidy them up without uploading the file.
Why this is useful
Metadata can reveal who created a document, on what software, and when — details you may not want to share when you send a PDF onward. Cleaning it in the browser means the file is never uploaded to do so. Be realistic about scope, though: this is best-effort cleanup of the standard Info dictionary. The Producer field will be set to the PDF library used, and embedded XMP metadata in complex PDFs may remain. It is not forensic anonymization or redaction.
How to use it
- Open the PDF Metadata tool and choose your PDF.
- Review the current title, author, subject, keywords, and creator.
- Edit the fields you want, or click Remove all metadata.
- Download the updated PDF — processed entirely in your browser.
Good to know
- Best-effort cleanup of standard metadata — not forensic anonymization.
- The Producer field is set to the PDF library used during processing.
- Embedded XMP metadata in complex PDFs may remain; not all hidden data is removed.
FAQ
Does it remove all hidden data?
No. It clears the standard metadata fields, but the Producer is set to the processing library and XMP metadata in complex PDFs may remain. It is not forensic anonymization.
Is my PDF uploaded?
No. Metadata is read and cleared locally in your browser; the file is not uploaded.
Can I edit metadata instead of removing it?
Yes — you can change the title, author, subject, keywords, and creator, then download.
