Reducing unnecessary document information before sharing
Sanitized PDF
Sanitization is not the same as redaction, encryption or guaranteed anonymity.
Privacy workflow
Clean unnecessary document information before sharing
Sanitization is about reducing information that does not need to travel with a document. It is different from redaction, which hides visible sensitive content, and different from encryption, which controls access to the file.
- External document handoffs
- Public or customer-facing PDFs
- Removing unnecessary document metadata and hidden information
- Visible sensitive content still needs redaction
- Metadata and embedded objects
- Links, attachments and other features required by the recipient
Think in layers: sanitize unnecessary information, redact content that must disappear, then encrypt when access needs to be restricted.

A human tip
The useful version of Sanitize Pdf
A conversion tool is most valuable when it removes the work around the conversion. People usually arrive with a destination in mind—an upload, a submission, an email, a report, a website or another editing step. The page should make that destination obvious, keep the interface focused, and offer a sensible next action when the first operation is only part of the job.
