Protect PDF — Privacy Privacy model, limits, and safety notes for Protect PDF. Open tool · How-to · Privacy Protect PDF privacy model This tool is classified as heavy workload and runs in Cloud Optional mode. Current status: coming-soon (limited). Release note: Password-protected writing is in progress and not available in local production mode yet. What this does Applies the selected transformation to the document or exported output. Keeps processing local in browser when marked On-device. Uses monthly local counters for usage quotas. What this does not protect It does not remove names or sensitive content visible in document text or images. It does not guarantee legal anonymity or endpoint compromise protection. For hybrid tools, privacy depends on explicit cloud opt-in when enabled. Password-protected PDF writing is not implemented. This tool does nothing. Even when implemented, PDF password protection is weak by design. RC4 and AES-128 encryption in PDFs are well-understood and quickly crackable. Safe workflow defaults Verify output manually before sharing. Use security guidance at /security for higher-risk scenarios. Keep original and transformed files separated to avoid accidental leaks.
