How MaiPDF Works

Upload Your Protected PDF

Simply upload your pre-password-protected PDFs to MaiPDF and start sharing them securely without any additional steps.

Dynamic Watermarking

Each PDF gets a unique QR code watermark containing access details like IP, time, and browser information for access analytics.

Advanced Access Control

Set viewing limits, control the time duration for which a document is accessible, and review who viewed your document and when.

MaiPDF vs. Traditional DRM Solutions

What is Adobe Content Server?

Adobe Content Server is a server-controlled approach to Digital Rights Management (DRM) introduced by Adobe for PDF documents (DRM PDFs). It was developed to protect digital books in formats such as PDF, EPUB, and EPUB3. However, Adobe’s solution is often expensive, and its reliance on specific software can be a limitation for end-users.

Additionally, Adobe Content Server’s model requires licensing fees, making it costly for small businesses and individuals to use.

Locklizard and Digify

Locklizard and Digify offer secure file sharing solutions with DRM and viewing restrictions. However, these platforms require users to install proprietary software or rely on specific file formats (like PDC for Locklizard). This limits flexibility and compatibility with various devices and platforms.

Unlike Adobe and Digify, MaiPDF allows you to share protected PDFs in a webview format without needing any additional software installation. It's an easy-to-use, flexible, and free solution for all users.

List of MaiPDF Features

Use Online Cloud Sharing for speed; use MaiPDF App DRM when screenshots, forwarding, or device access matter

SendPDFOnline pages now describe MaiPDF as a two-level product family: Online Cloud Sharing creates quick browser links and QR codes, while the MaiPDF App creates protected .maipdf packages for sensitive PDFs that need App DRM controls.

Fast cloud link

Upload a PDF, share a browser link or QR code, and keep read code / modify code management.

Protected .maipdf file

Package the PDF in the MaiPDF App with local encryption, license rules, expiry, open limits, and revoke control.

App-only protections

Use protected viewer, device binding, screenshot-aware controls, watermark trace, and license management where supported.

No web page can fully stop screenshots. MaiPDF App DRM is positioned as the stronger path: reduce casual copying, bind access to identity/devices, revoke licenses, and trace leaks with visible watermark information.
