PDF metadata

See what a PDF says about itself — then strip title, author, producer, and dates before sharing.

Local processing

Processed in this tab. File bytes are not uploaded. How local processing works

Cleaning rewrites the document's info fields (title, author, subject, keywords, creator, producer, dates). Page content is untouched. Some unusual custom metadata embedded outside the standard fields may persist — this tool removes the fields readers and preview tools actually show.

Free, no upload — pass it on:

Before you start

FAQ

What metadata does a PDF contain?
Typically a title, author, subject, keywords, creator/producer software, and creation/modification dates — plus sometimes custom fields.
Does cleaning change the document?
Only the metadata fields are rewritten — page content, images, and fonts are untouched. Unusual custom metadata outside the standard fields may persist.
Is my PDF uploaded?
No. The document is read and rewritten in this browser tab. You can verify it — no file bytes are sent anywhere.
Why remove PDF metadata?
Author names, editing software, and timestamps can reveal more than intended when sharing a document publicly.

Processing runs locally in your browser — no upload. Outputs are generated on-device. For the privacy boundary see the local processing guide.
