Terms of service for Google Docs Viewer

Is it permissible to utilize the docs.google.com/viewer (or docs.google.com/gview) service to display a preview of various file types such as documents and PDFs on our commercial website? Additionally, are there alternative options available from Google Docs that would serve this purpose?

Based on my experience with Google’s API services, using Google Docs Viewer on a commercial website can sometimes be tricky when it comes to terms of service. Google provides these tools for personal use primarily, so you might face issues using them for commercial purposes. It often requires explicit permission or a special agreement with Google. Alternatives you might consider include embedding documents using the iframe method, or using product-specific third-party services designed for document preview. Exploring Google Workspace might also give you some legitimate business options.
