Overview

F

FileOpen

FileOpen gives you complete control over your digital assets by applying persistent security to PDF and Office documents. Instead of relying on simple passwords that can be shared, you can encrypt your files and define specific access rules that follow the document wherever it goes. You can expire access remotely, limit printing, and prevent screen captures even after a user has downloaded the file to their own device.

The platform integrates directly with your existing workflows, allowing you to manage permissions through your own website or database. Whether you are a publisher selling high-value reports or a corporation protecting internal trade secrets, you can ensure that only authorized users view your content. It eliminates the risk of unauthorized redistribution while providing a seamless viewing experience for your legitimate customers and employees.

Nitro PDF Pro

Nitro PDF Pro provides you with a powerful alternative to Adobe Acrobat for managing your digital documents. You can edit text and images directly within PDFs, convert files to and from Microsoft Office formats, and merge multiple documents into a single searchable file. It simplifies your daily paperwork by letting you highlight, annotate, and add comments to collaborate with your team effectively.

The platform also focuses heavily on security and official workflows. You can apply password protection, redact sensitive information permanently, and request legally binding e-signatures without leaving the application. Whether you are a solo professional or part of a large enterprise, it helps you eliminate paper-based processes and speed up your document turnaround times.
