About Viewer app

Computer applications store information in files of different types. Processing files of a certain type often requires specialized software that takes up a lot of space and sometimes is not free. However, you will not install a software package that is ten gigabytes or more and even pay for it to view one file. Also, you can get the file on your mobile phone, but many software packages do not have mobile versions. Of course, you can get to the computer, but sometimes it takes time, and the computer may not have the necessary software.

GroupDocs.Viewer is a fast and efficient API for rendering over 170 different file types. Powered by a high-performance cloud-based GroupDocs server, it displays files in the browser. GroupDocs.Viewer technologies make it possible to achieve an ideal and identical display of a document on any platform.

This free online application based on the GroupDocs.Viewer API displays files of various formats on your device. We value your privacy, so the file is visible to you only. You can print the file you are viewing directly from your browser. You can also download the PDF file to share with someone or view later. The application works on any device, including smartphones.
