While most viewers require the entire file to be downloaded before it can be opened and viewed, with PDFTron technology, viewing partial content for online PDF is made simple. Showing partial PDF content while downloading on demand provides fast and responsive PDF viewing experience. For example, you can see the beginning of the content almost immediately, and if you move to the middle of the content, it is prioritized and loaded very quickly, before other parts. Online PDFs can be viewed the same way as one can stream an online video.
