【實用商業app】The Fastest PDF Reader|最夯免費app-綠色工廠好玩App

This is not your average PDF Viewer. Because not all PDFs are ordinary. Now with annotation capability, you can write on or sign your PDF. Add notes, make corrections or complete a contract with your actual signature. Imagine receiving an 8,000-page document. Or a 36” x 24” chart. We can open those. And we can do it instantly. No other app can say or do that. Can act as a cloud server so you can upload/download/mange files and folders from your desktop browser.PDF provides screaming fast opening, viewing and drawing times for all complex PDF files. As well as the ability to handle huge documents, both in size and length. If we can manage huge documents like this, wait until you see how quickly we deal with a normal 8½ x11 or A4 size file.    Why wait? Get PDF now. Never again will you have to deal with documents that take forever to open, are slow to scroll or take a long time to draw each page. In addition to speeding up your viewing experience, PDF also supports: ● sharp image detail ● internal and external bookmarks ● rotation and locking ● directional scroll lock  ● printing  support ● sharing via email ● dragging & dropping of any file from iTunes  ● variable page size support (especially tuned for photo-scanned books from Archive.org ) ● opening of Mail documents ● read-only Dropbox support  ● seamless page boundaries, vertically or horizontally.  ► Our satisfied clients write:   "I bought this app because it claimed to be very fast and handle long documents well. It is excellent and significantly faster than the other PDF readers I have purchased. It is fast, simple and stable which is all I need from a PDF reader. I would recommend it if, like me, you have a need for speed and simplicity.” "  I've used PDF specifically to read PDFs of large-sized school newsletters (best reader of the seven to ten I've bought to read these types of documents). Perfect! The pre-rendering feature is brilliant. No more checkerboard. Highly recommended.”   "I love this app! Fast. Pre-rendering function rocks. I'm totally freed from the stress of waiting.  ” “Beautiful. When I read wide books in other apps, usually I need to magnify in order to read small characters. But this shows characters very clearly, so I don't need to do that."   "Many thanks for your super quick response. Very impressive customer service."   "This is simply an amazing solution on the iPhone. And even more so on the iPad."
