    Is the Ipad capable of receiving large pdf files and how do they look on screen?

    Use Goodreader and see for yourself, I believe it is free.

    Thank you. I do not have an Ipad but I am considering and researching. I have rather large table-heavy pdfs I would like to be able to view on a reader or Ipad

    I use my iPad to read large PDF documents, up to 200 pages so far. I access them through Dropbox and read them with Goodreader or Docs to Go. Tables look just fine. IBooks now also reads pdf's and looks good.

    I have been translating files out of Indesign to Dreamweaver as html files for a while to be read on a kindle and last I looked kindle can not read pdfs.

    Ebooks, you mean for the sony reader?

    I tried a large and heavy graphic PDF on my iPod Touch 2nd geneneration and it transferred fine using iTunes but refused to open on iBooks. On the iPad it opened fine.

    The GoodReader is 99¢, but the iBooks app will also do PDF's.... and its FREE. All you do is open iTunes (makes sure its the latest and greatest - v9.2.0.61) and click on Books on the left side of the screen. Now open your Explorer (This is in Windows. I don't know how to find files in a Mac.) and locate the files you want to copy. Now you can either drag the file from your Explorer window to the Books window or just copy & paste. Sync your iPad and voila... you now have PDF's! I just did this and if a Windows person can do it, how hard can it be???

    Frankly, I wasn't a big fan of the iBooks app... until now!

    Is anyone out there having trouble with sending PDFs that can be read by Google docs or Adobe? If I send a PDF from Pages it comes up blank in google docs, or if read by Adobe on a PC the layout and fonts are all over the place or missing.
    Am I the only one experiencing these problems?

    Do you know any app or any conversions that can read compiled HTML, docx and mhtml in iPad?

    Also, When you mentioned large PDF documents doesnthis include scanned pdf's files? I have some files that can't be viewed by either goodreader and docs2go. Using goodreader I got the message that it is because it's a scanned file. So it ended as blank pages.

    The largest pdf i read to date using ibooks was a 129 MB graphics rich magazine. worked fine for me.
    I read a 37MB scanned pdf in ibooks without any problems. But I have also come up with blank pages in certain other scanned pdfs . Do not know why!

    It seems there are a handful of us who encountered these PDF that turned into blank pages. I hope someone drops by this forum and can offer a great solution.

    I guess if the pages are scanned as picture (png/jpeg?) and then combined together to form a pdf the pages display blank. This is my guess. can someone validate this?

    Hi there. I think I could offer you some help on why this is happening. I am a digital artist and I work with a very powerful computer that I put to it limits. As a reference I increased the memory on one computer to 10 gigabytes of RAM because a similar situation was happening to me and it now works fine.

    If you open this 129 mb document on a desktop computer (powerful enough) and it displays fine then the problem is with your iPad's processing power and memory (a limit). And if the document displays errors or blank pages too on a desktop computer the problem may be again the processing power and memory But with the computer used to generate the document. The same PDF program running on a limited computer may bypass some pages or information when it reaches its limits but because the program is somehow efficient it continues to work doing "the best it can".

    As a reference, my iPod Touch second gen with 128 mb of memory running iBooks can't even open a complex 12.6 mb PDF full of graphics and iBooks collapses and closes. But my laptop or desktops have no trouble with it.

    This problems start to happen when the memory or the video memory reach it limits and the iPad has 512 mb which is adequate for most situations but is not that large. This 512 mb are the active memory for the system and not to be confused with the hard drive's 16 to 64 gigabytes the iPad has for the user movies, apps or files. The 129 mb PDF you are reading is large, but also consider closed documents are smaller in size as they are compressed. The same open document displayed inside the 512 mb memory with every page fully loaded, plus the memory for the program is using, plus the memory for the system and other apps running on the background may be using all the memory the iPad has.

    Sometimes just One very complex and demanding page could cause this as the page could contain several layers with a lot of complex drawings, pictures and text. You may think it is only another page but it may demand more memory and processing power too from the system to display the page. But now you may try to navigate back and forth and the system will need to load and maintain in memory a lot more information.

    Also a scanned document is a collation of picture files unless you use the OCR conversion. If you have a 100 page scanned document this is equivalent to a 100 page picture magazine or book and not equivalent to a 100 page text book, even if they look very similar to you. It may not be enough to collapse your desktop or laptop this days but it may put your iPad to it limits. Remember the iPad is a powerful but small computer.

    Please, if someone else could provide more accurate information it will be nice.

    Using Goodreader, pdf files that I've downloaded include books, marketing materials, and charts and graphs and they all look great on the iPad.
