Remove PDF metadata before sharing

Review and clean supported PDF title, author, creator, keywords, dates, and XMP fields.

Quick answer

Metadata cleaning helps remove supported document properties such as title, author, subject, keywords, creator, producer, saved dates, custom fields, and XMP entries. It does not remove visible names, comments, attachments, hidden layers, form values, JavaScript, or sensitive images on the page.

When this guide applies

  • External sharing
  • Client packets
  • Public posting
  • Files created from office software

When not to use this guide

  • Do not use metadata cleaning to remove visible text on pages.
  • Do not expect comments, highlights, attachments, or form values to be cleaned automatically.
  • Do not treat missing displayed fields as proof that every hidden privacy risk is gone.

Checklist

  • View supported document properties before sharing.
  • Remove title, author, subject, keywords, creator, producer, date fields, custom properties, and XMP data when appropriate.
  • Save a cleaned copy instead of overwriting the original.
  • Run annotation removal separately when comments or highlights are present.
  • Review visible page content for names, IDs, and images that metadata cleaning cannot remove.

Risks to check

  • Author and creator fields can reveal names, systems, or internal workflows.
  • Date fields can reveal document history or revision timing.
  • Cleaning metadata without checking visible content can create a false sense of privacy.

Limits to know

  • Metadata cleaning is limited to supported document property structures that the browser library can read and rewrite.
  • Visible content, annotations, attachments, form values, hidden layers, scripts, and embedded images are separate review areas.
  • Some vendor-specific fields may not be exposed consistently by every PDF library.

How to verify the result

  • Open the cleaned copy and view document properties again.
  • Check that visible page content still reads correctly after cleaning.
  • Inspect comments, attachments, forms, and sensitive visible text separately.
  • Keep a private original if the metadata is needed for internal records.

Guide FAQ

What PDF metadata should I check before sharing?

Check title, author, subject, keywords, creator, producer, creation date, modification date, custom properties, and XMP metadata when the file is privacy-sensitive.

Does removing metadata remove comments too?

No. Comments and highlights are annotations, not ordinary document properties. Use annotation removal and then verify the comments panel.

Can metadata cleaning remove visible names on a page?

No. Visible names, account numbers, signatures, and images are page content. They require editing or redaction workflows, not metadata cleaning.
