The program uses a low-to-moderate amount of system resources and comes with a comprehensive user manual. In the 'Options' menu, you can select the default layout and zoom, disable the options to show the bookmarks sidebar when available, remember current settings for each document, automatically check for updates and remember opened files, as well as make SumatraPDF your default PDF reader. You can change the interface language (there are numerous options to choose from), use a search function, print the document, use keyboard shortcuts and command-line arguments. You can rotate the page left or right, go to a particular page number, zoom in and out (up to 6400%) as well as create a favorites list. Thus, you can view document properties (file path, date of creation, application, PDF producer and version, file size, number of pages, page size), as well as change the view to facing, book, presentation, full screen, and others. You can import a document by using the file browser or via drag-and-drop simple gestures. The user interface of the program consists of a plain window in which navigating is done seamlessly. SumatraPDF is a useful tool that makes it as simple as possible for you to view documents in the PDF, CHM, DjVu and XPS formats, as well as comic books.
