To strip metadata, use the PDF compress / re-save tool (coming soon) or open in a PDF editor and re-export.

À propos de cet outil

View and edit the metadata embedded in a PDF - title, author, subject, keywords, producer, creator, creation and modification dates. Useful for clean publishing (filling in missing fields before distribution) or for stripping personal information before sharing publicly.

Privvert reads the existing metadata, lets you edit each field, and writes the file back without touching page content. Runs entirely in your browser.

Questions fréquentes

Why strip metadata?

PDF metadata can contain your real name (in author), the editing software you used, and timestamps that reveal your workflow. For public publishing or anonymous sharing, strip it.

Does this remove embedded fonts or images?

No - only the document properties (title, author, etc.) are changed. Page content is untouched.

What's the difference between Producer and Creator?

Creator is the application that originally made the content (e.g. Microsoft Word). Producer is the tool that generated the PDF itself (e.g. 'Adobe PDF Library'). Both are usually filled in automatically.

Will form data, annotations or attachments survive?

Yes - they're not metadata fields. Use the relevant tools (organize, redact) if you need to modify them.

What metadata does a PDF normally contain?

The PDF info dictionary holds title, author, subject, keywords, creator (the program that built the original document) and producer (the program that wrote the PDF). Many PDFs also carry an XMP metadata block with the same fields in a structured XML format.

Why does my PDF still show my name after I clear the author field?

There may be a separate XMP block carrying the same data. This tool clears both. If the name comes from inside the document content itself - a header or footer - that's page content rather than metadata and needs to be redacted.
