Know the limits

Local does not mean unlimited.

Browser processing protects the file from an upload workflow, but the browser, device, output format, and selected settings still matter.

  • This is not malware scanning or complete PDF sanitization.
  • It does not redact visible page content, hidden text, attachments, scripts, or prior external copies.
  • Some malformed, encrypted, signed, or unusual PDFs may be rejected or altered when rebuilt.

Clear answers

PDF privacy inspector questions.

Does this redact text inside the PDF?

No. It removes supported document properties only. Visible text and page content require a dedicated redaction workflow.

Can the cleaner break a digital signature?

Yes. Rebuilding or modifying a signed PDF can invalidate its signature. Preserve the original whenever signatures matter.

Is the PDF uploaded?

No. The PDF library reads and rebuilds the selected file in this browser.
