Share PDF online — generate secure links with MaiPDF

What Makes MaiPDF the Best Way to Share PDFs Online?

MaiPDF is built for secure PDF sharing with control: encrypted links, view limits, expiration, watermarks, and who-opened analytics. Unlike generic cloud storage, you decide who sees your file and what they can do.

Example: Share a proposal with 7-day expiry, 3 views per person, and a watermark with the viewer’s email — you keep full control.
