Local PDF metadata remover

Ready for a PDFFree · no signup

Inspect, remove, and verify PDF metadata

Choose one PDF to review its supported metadata first. Cleaning creates a new rewritten file, removes document properties and catalog XMP, then checks the result again.

What the PDF metadata remover changes

A structural rewrite, followed by a second scan

The cleaner removes both supported metadata references and asks qpdf to write a new PDF. It then checks the same locations again and refuses to claim success if metadata remains or the page count changes.

Document properties

Title, author, subject, keywords, creator application, producer, dates, and other supported entries from the PDF Info dictionary.

Catalog XMP

Supported Dublin Core, Adobe PDF, XMP, rights, and location fields from the catalog Metadata stream.

Verified output

The output is re-scanned for both supported metadata locations, with page count preservation and signature consequences reported explicitly.

Exact capability boundary

Removing PDF metadata is not the same as hardening a PDF

This tool has a deliberately narrow, testable promise. It handles standard document properties and catalog XMP only. A security hardening workflow would need separate rules, previews, and evidence.

Included here

  • Inspect the PDF trailer Info dictionary.
  • Inspect the catalog-level XMP metadata stream.
  • Remove both references, rewrite, and re-scan a new copy.
  • Run the file workflow locally in a browser Web Worker.

Not included

  • No claim of PDF sanitization or security hardening.
  • No removal of scripts, actions, attachments, forms, or annotations.
  • No search for hidden text, redactions, layers, or metadata inside embedded files.
  • No processing of encrypted or password-protected PDFs.

A visible local workflow

Inspect first, then rewrite and verify

No cleaning starts until you can see what was detected and accept any digital-signature consequence.

  1. 01

    Inspect

    Read supported document properties, XMP, page count, and signature markers before changing anything.

  2. 02

    Rewrite

    Remove the supported metadata references and use qpdf WebAssembly to create a new PDF.

  3. 03

    Re-scan

    Check the new PDF again and only enable download after metadata absence and page count are verified.

PDF metadata questions

Clear answers before you inspect or remove

The important part is knowing what the tool can prove, what rewriting changes, and where a separate security workflow is still required.

What PDF metadata does this remover delete?
It removes the trailer Info reference and catalog Metadata reference from a newly rewritten PDF, then re-scans those locations. It does not claim to remove metadata stored inside attachments, page content, annotations, or other embedded objects.
Does the PDF leave my device?
No. Reading, rewriting, and re-scanning run in a local browser worker. The tool does not send the filename, PDF bytes, metadata values, or a file hash to a processing API.
What happens to a digitally signed PDF?
Any rewrite invalidates the existing digital signature. The remover detects common signature structures conservatively, explains the consequence, and requires explicit consent. It does not validate the signer or certificate.
Can it process password-protected PDFs?
No. Encrypted and password-protected PDFs fail closed and remain unchanged. Password entry and decryption are outside this local tool's current scope.
Does removing metadata make a PDF safe?
No. Metadata removal is not PDF sanitization. Scripts, actions, forms, attachments, annotations, hidden page content, redactions, and embedded files require a separate hardening workflow.
What are the current file limits?
The tool processes one PDF at a time, up to 25 MB. Malformed PDFs, files that require structural recovery, and encrypted PDFs are rejected without creating an output.
