Bring accurate, reliable and fast support for Microsoft® Office formats to any iOS, web, Windows, Mac or Android software. PDFTron’s fully supported Office SDK is the first solution to view Office documents directly on any browser or app - no conversion or server dependencies required.

Launch Demo

View Office Files on Any Platform

Ensure reliable, high-fidelity rendering of .docx, .doc, .xlsx, .pptx and 20+ other formats on all platforms and devices, including iOS, web, Linux and Android.

No Dependencies or MS Licenses

Support Word, Excel and PowerPoint formats without you or your users needing any MS Office software, MS Office licenses, or third-party open-source software.

Client-side

Let users view, annotate and print .docx, .xlsx, .pptx files, and convert to PDFs - all entirely client-side. Automatically stamp documents with an image, text, or a date.

Real-time Collaboration

Have annotations from many users appear on the same Office document in real time while preserving an original version of the file. Manage annotations in a separate XFDF layer. Add roles, permissions or an audit trail.

Fully Customizable UI/UX

Increase adoption and productivity by simplifying the open source UI. Match your desired look and feel. Hide unnecessary features -- or add custom annotations that trigger workflows.

Add Even More Functionality

Speed time to market with an Office SDK -- supporting all major platforms, 30+ file formats, and many unique features.
