Use this simple trick to add all your favorite PDF files to iBooks on your iPhone or iPad.

With iOS4 comes a handy little application called iBooks. With iBooks you can read all your favorite eBooks at the comfort of your iPhone or iPad. But you would be surprised to know that can also read all your favorite PDF files using iBooks on your iPhone or iPad.

Adding PDF files to iBooks is relatively simple and straight-forward.

First, make sure you click on the Books folder on iTunes so it is selected. You might see the sample eBook on your Books folder. Keep it or you can delete it, your choice.

Find the PDF file that you wanted to add to your iPhone. Drag and Drop the file into the Books folder on iTunes.

If you wish to add some metadata about the PDF file you can do so by using the “Get Info” option when you right-click on the PDF file in iTunes. It’s an optional step but would certainly help if you have a lot of books on iBooks and wanted to identify them quickly.

Now that’s been added to Books on iTunes you need to make sure that new PDF get synced into your iPhone or iPad. Go into your iPhone folder and click on the “Books” tab. Make sure “Sync Books” is checked. If “Selected Books” is checked then make sure to check the PDF file that you wanted to get into your iPhone. Once done, hit the Sync button.

Your new PDF should show up on your iPhone. You might be surprised to see that it’s not showing up by default. Once in iBooks you need to tap on the “PDFs” tab to see your PDFs.

Now that you know how to load all you favorite PDFs in to your iTunes you might need to make sure couple of things,

• Do not load PDFs that are huge in size.
• Do not load PDFs that are in violation to any copyrights.
• Do not load PDFs that would be hard to read on the tiny screen of your iPhone.

I hope this helps you make use of all the valuable PDF files that you have in your computer. I certainly started reading a bunch of my favorite PDFs otherwise would have never bothered to read.
