This software allows you to easily open PDF, DjVu, ePub, and comic book files while also providing the ability to add annotations and bookmarks to your documents. It is user-friendly and intuitive.

Once installed on your computer, SpdPDF Reader automatically associates itself with the PDF filetype. This means that PDF documents can be opened in SpdPDF Reader simply by double-clicking on them in the file explorer. However, it does not interfere with associations with other filetypes that it supports.
SpdPDF Reader provides a user-friendly interface with an intuitive layout. This software allows you to keep multiple documents open at the same time and easily navigate them in different tabs. You can add bookmarks and explore the table of contents to jump to specific chapters of a book.
The application has a multi-tabbed interface with bookmarks and tables of contents. In addition, it can switch to fullscreen or slideshow mode. The slideshow mode has a dark background and displays one page at a time, which is ideal for graphical content. The fullscreen mode has a light background and displays the pages in continuous view, which is ideal for reading.
SpdPDF Reader offers various functionalities, such as zooming in and out of pages, finding an exact word or phrase using real-time search function, and viewing one or two pages at once. It is also possible to rotate pages from the options menu, disable scrolling, and remove the PDF filetype association with SpdPDF Reader.
One minor issue is that the annotation options are available in a separate section from the reader (click 'Annot' on top of the window, next to 'Reader'). These tools only work properly for PDFs, and you can add text anywhere on the pages, highlight text selections, and so on.
In conclusion, SpdPDF Reader is an excellent tool for viewing PDF documents and other file formats. It offers a user-friendly interface, multiple functionalities, annotation options, and efficient performance. Its ability to support various file formats makes it stand out from other PDF readers, while its lightweight design provides a faster and smoother reading experience.
