WebViewer: Feature-Rich JavaScript PDF Viewer

WebViewer is a JavaScript library for document viewing and editing that allows you to view and annotate PDFs, manipulate pages, and edit DOCX documents. All document processing, such as rendering and editing, occurs securely in a browser through a web assembly module. This eliminates the need for a server-side backend and enables easy scalability.

Apryse’s fully supported WebViewer is trusted by thousands of innovative startups, governments, and Fortune 500 businesses (see customers). Apryse technology is built from the ground up and is not dependent on any external third-party open-source software.
