GroupDocs.Viewer for Node.js via Java combines a powerful set of document viewer APIs to display image and document formats without needing to install additional software. It natively rasterizes documents and converts them into SVG, HTML and CSS to enhance the quality of document viewing while delivering a true-text, high-fidelity output. You can quickly view PDF, HTML, XML, Microsoft Word, Excel worksheets, PowerPoint presentations, Outlook emails, Visio diagrams, Project, metafiles, images and various other file formats. It can also display password-protected files and allow you to get document representation as HTML, image or PDF after rendering.
