Out-of-the-Box Web UI

The library comes with a web UI, which gives users all the options they may need to read and browse documents online, including:

  • Ability to scroll or turn pages like slides
  • Preview and navigate pages with thumbnails
  • Jump straight to any page within the document
  • Search for text within a document using keywords
  • Select and copy text to the clipboard
  • Fit to width/height/visible and zoom in/out of the document
  • Print the document from a browser
  • Download the original file
  • Annotate the document (please contact sales for this feature)

Easy to Customize

Adopting the viewer's interface to fit with your own app is easy. Simply customize the color scheme, toolbars and button styles by tweaking CSS. And the client-side JavaScript framework allows you to enhance the viewer with custom functionality.

UI Localization

The UI can be localized to any language through the API. Also, there are the following UI localization options currently available for your choice:

  • en-US - American English, the default
  • es-ES - Spanish
  • pt-PT - Portuguese
  • nb-NO – Norwegian

Document Caching

Recently displayed documents are automatically added to cache, so that subsequent document requests can be processed faster. Documents are cached on the server when loaded for the first time. If a user tries to view a document that is already in cache, it loads much quicker. And thanks to the AOT (ahead-of-time) caching, you can add certain documents to cache manually, before they are requested by users.

Secure Document Sharing

If you don't want users to download an original file, but still want to share the document with them, you can either disable the download option, or set the viewer to automatically convert the shared document into PDF format. With this option enabled, the original file hosted on your server stays intact, and users only get a PDF copy when trying to download it.


The documents you display can be protected with text watermarks. Watermarks are rendered above the document on the client side only, the original file hosted on your server is not modified.

Simple to Integrate

The library is packaged as a single JAR file and can be easily integrated into your app hosted on any Java servlet container. The web UI can be embedded into your app with just a few lines of JavaScript code or an iframe. There is no need to install anything on the client side at all.
