Sharing a PDF is easy; keeping control after you hit send is hard. MaiPDF gives you granular access control so you decide who opens the file, how many times, and for how long — layered with watermarks, verification, and optional no-download viewing. Whether you are sending NDAs, investor decks, or pricing sheets, you can enforce policy without mailing attachments that disappear into inboxes forever.
How It Works
Open MaiPDF and upload your document. You can start from the homepage without a lengthy signup flow, then move straight to security settings.
Set expiration, view caps, password protection, email verification, watermarking, and Telegram notifications. Combine controls to match your risk level.
Distribute a single link or QR code. Recipients only get what you allow — and you can revoke or replace access from your dashboard at any time.
Fine Control
View limits stop a single link from turning into unlimited circulation. Set a maximum number of opens for the whole file or per recipient, pair with expiration, and combine with watermarks so that when the cap is hit, access simply stops — no manual cleanup after the fact.
Controls
Set a start and end time or a fixed expiry so the link stops working when the campaign or review period ends.
Restrict how many times the document can be opened so confidential material cannot be passed around indefinitely.
Overlay viewer-specific details on each page to deter screenshots and support traceability when content leaks.
Require recipients to prove they own an allowed email before the PDF opens — no anonymous forwarding.
Add a shared secret so even if the link is leaked, the file stays closed without the password.
Keep the document in the browser viewer with DRM-style restrictions that reduce offline copies and printouts.
Disable or rotate links from your dashboard when a deal stalls or a person leaves the project.
Get instant notifications when someone opens your PDF so you can act on access events as they happen.
