Why PDF security matters
PDF files are widely used to share important information like contracts, invoices, reports, certificates, and ID scans. Adding a password ensures only trusted people can open them. At the same time, sometimes you need to remove a password for easier access or sharing. LockDocs gives you both options in one clean, easy-to-use app.
