DirectOffice® Mobile SDK

DirectOffice® Mobile SDK adds native, high-fidelity Office document rendering to your iOS and Android™ applications.

Today, more and more business users are working away from their desks and PCs. Documents are often stored in the cloud or on mobile storage devices and accessed on phones and tablets.  Users expect existing Office documents to look the same on their mobile device as they do on their desktop PCs. DirectOffice Mobile SDK enables Office document viewing and printing with PC-like fidelity in your mobile app.

DirectOffice Mobile SDK is a standalone library you add to your app. Documents are securely rendered directly on the device in your app's sandbox. DirectOffice Mobile SDK works on iOS and Android giving the same great fidelity and consistent user experience across devices.

Matching the fonts contained in the original document is key to great looking output. DirectOffice Mobile SDK includes an intelligent font matching system to ensure that the text and document layout appear as intended.
