When this tool is useful
Correcting title, author, subject, and keywords before routine sharing or cataloguing.
How local processing works
The browser reads supported document-info fields, applies explicit replacements or removals, and writes a fresh PDF.
How to use it
- Prepare Edit PDF metadata: Work from a copy and confirm each old and new property, intentional blanks, filename, attachments, and the disclosure threat model. Keep the source unchanged.
- Apply Edit PDF metadata: Process locally in the browser. The browser reads supported document-info fields, applies explicit replacements or removals, and writes a fresh PDF.
- Download and verify: Save under a new name. Inspect properties in another reader, search visible pages, review attachments and filename separately, and use specialist sanitization for high-risk release.
Important limitations
This is not forensic sanitization: visible content, filenames, XMP variants, attachments, annotations, hidden objects, revision traces, and embedded files may still disclose information.
Verify the downloaded result
Inspect properties in another reader, search visible pages, review attachments and filename separately, and use specialist sanitization for high-risk release.
Private by design
