About
Protect before you share.
DocTrace turns PDFs, DOCX files and images into a protected PDF ready to send. Document content is processed on your device and is never uploaded to DocTrace.
CHOOSE THE RIGHT LEVEL
• Password — require a password to open the protected PDF.
• Confidential — add a password plus a visible watermark with recipient and date.
• Traceable — add the Confidential protection plus a unique DocTrace ID in multiple parts of the PDF, so a copy can be checked against your local history.
LOCAL BY DESIGN
• Import PDF, DOCX, JPG and PNG files, plus HEIC when supported by the device.
• Preview the result before protection.
• Keep the original file unchanged.
• Reopen and validate the protected PDF before sharing it.
• Keep passwords out of history and remove temporary files after the operation.
• Use the system share sheet without creating a DocTrace account.
Traceable does not monitor opens, contact a server or report recipient activity. It embeds an identifier that you can verify locally if you later receive a copy.
PDF passwords, watermarks and usage restrictions reduce casual access and reuse, but they are not DRM and cannot prevent screenshots, photography or deliberate reconstruction. Share the password through a separate channel.
Use DocTrace for contracts, proposals, invoices, certificates and other confidential documents that need a safer step before Send.
