Which PDF sharing method should I use for clients?

Use a secure share link with password, expiration date, and optional watermark for most client workflows.

When is QR code sharing better than links?

QR sharing is best for offline materials such as brochures, event booths, and printed proposals.

Can I track who opened my shared PDF?

Yes. MaiPDF provides access records including open time and viewing activity for your shared documents.

How do I reduce unauthorized forwarding?

Enable view limits, set expiry, disable download when needed, and apply dynamic watermarking.
