What kind of information gets removed?
PDFTasker targets common hidden document fields such as author, title, subject, keywords, producer, creator, app metadata, and XMP metadata when present. These fields can reveal names, software, workflow history, or organizational details that are not visible on the page but can travel with the file.
Does this change the visible content or layout?
The goal is to remove hidden metadata without changing visible pages. Text, images, signatures, and layout should remain the same. Still open the cleaned copy before sharing, especially for official forms or published PDFs, because any cleanup step should be verified like the final document.
Do you upload the file to analyze it?
No. Scanning and cleanup happen in your browser. That is the point of a metadata cleaner: sending a private PDF to a server just to remove hidden traces creates a new trust problem. Local cleanup keeps the document on your device during the process locally.
Can metadata removal guarantee anonymity?
No. Metadata cleanup reduces common hidden fields, but it cannot guarantee anonymity. Visible text, images, comments burned into pages, file names, QR codes, watermarks, or recipient history can still identify people or organizations. Treat sanitize as one pre-share step, not a complete privacy audit before release.
When should I sanitize a PDF?
Sanitize before publishing, forwarding, uploading, or sharing a PDF outside the original context. It is especially useful for resumes, contracts, tenders, research drafts, client documents, and scans created by office software. Keep the original, then send the cleaned copy through the required channel only afterward.
