Document Viewer API

Render and display documents for true zero-footprint viewing. Using PrizmDoc's document viewer API, you can convert any document or image into a web standard format and display them easily in a web browser on any desktop or mobile device. Embed the customizable viewer into your web or desktop application in just a few lines of code. Zero installation is required on customer devices because everything they need is already in the browser.


Functionality That Speeds Up Your Development Time

Rather than taking time to custom build your own HTML5 viewer, you can rely on Accusoft's 25 years of document imaging expertise to provide the innovative tools your application needs.

Give your users the ability to view, share, and collaborate across dozens of different file types within your application or content management system, including PDF, JPEG, CAD, and many more. This provides a seamless experience that completely eliminates the need for users to rely on browser plugins or third-party applications to access files. Plus, they'll have access to high-performance features that can help set your application's functionality apart:

Large Document Viewing and Server-Side Search

This feature minimizes load time and optimizes performance for viewing and searching large documents. Compared to leading word processors, PrizmDoc loads documents with over 1,000 pages much faster. In seconds, compared to minutes, the document is ready to view and search. Since large documents can take an excessive amount of time to load, you risk the viewer crashing when the browser memory becomes overwhelmed.

Server-side search reduces the memory load in the viewer, dramatically increasing performance of large document search results. PrizmDoc reduces the memory by rendering only the pages a viewer needs, rather than all the pages in order.

Microsoft Office (MSO) Conversion

For companies that require native rendering of Microsoft Office files, PrizmDoc's MSO Conversion feature is a valuable viewer add-on that provides true native viewing of Word, Excel, and PowerPoint documents. This can help your users meet compliance requirements as well as overcome fidelity issues when working with MSO files.

MSO Conversion is included with cloud-hosted PrizmDoc can be purchased as an add-on option for PrizmDoc Self-Hosted.
