Privacy & how PDF tools work
- Are online PDF editors safe? How to judge before you upload
What safety really depends on when you upload a PDF — transport encryption, server retention, policies — plus a practical checklist and a local alternative.

What browser-local PDF editing means, why it protects contracts and medical records, and everything pdfmend can do without your file leaving your device.
