Have an ipad as well as lots of pdf files, are you finding a way yo manipulate pdfs on the ipad?
The ways to manipulate PDFs on the iPad are numerous, depending on which app you are using to read the document. The iPad's native software allows you basic viewing for PDFs with limited options, while other apps from the App Store allow you to organize, further manipulate and even annotate your PDFs. You can get started with preinstalled software or a free downloadable app, then add apps with more features as your PDF needs grow.

1. Open the PDF you want to work with if it is already on your iPad. If not, email it to yourself, and then tap the attachment to open it on the iPad.

2. Swipe your finger upward on the screen to scroll the PDF up, or swipe downward to scroll down.Double-tap an area on the PDF to automatically zoom into that area, and double-tap again to zoom back out.

3. Zoom to custom levels by placing two fingers on the PDF and spreading them outward to enlarge the PDF. Pinch your fingers toward each other to zoom to a smaller size. Tap the PDF once to raise the menu options.

4. Tap "Done" in the upper left menu to return to your email if you are using the email viewer. Tap the send/share button, also called the action button, in the upper right corner to open a list of other PDF-compatible programs.

5. Send the PDF into another program from the action button list if you want to highlight, annotate, bookmark or perform any other tasks with the PDF.

6. Follow each individual app's instructions to manipulate the PDF within that app. For example, GoodReader uses a tap to the right or left to advance and retreat pages, rather than the swipe method. iBooks uses a bottom corner page swipe, as if you were turning the page of a book.
