I have put a total of 20 PDF files of science journal articles onto my Ipad and 5 of these, from various journals, cause the PDF reader app (both GoodReader and PDFReader Pro) to crash when they arrive at a particular page within the PDF. These PDF files are fine when I open them with Acrobat on my Windows 7 based laptop. The PDFs always crash at the same page regardless of the app that I am using to read them.

Has anybody else experienced this? And does anybody have suggestions about solving the problem.
Thank you

HP, Windows 7

    I had the same problem last night, using GoodReader. I'll have to remember to try the problem PDF with the native PDF viewer and see if the same thing happens.

    This happens to my iPad as well. I do not understand why native pdf viewer on iPad also has a problem. I thought first it is problem with specific apps but it seems not.

    Have same problem regardless of reader app on ipad.

    I print the files which causes crash on iPad in PDF on my Mac. That can temporarily solve the crash issue. No crash!

    ok... APPLE please listen... Using Macbook right now

    Open PDF link using Safari... Safari downloads file then I open it in either Preview or Adobe Reader then save it... saves at 444KB. I then saved it to my idisk, opened it with my ipad using any reader and it crashes the app.

    Then, same routine, but with Firefox, same pdf open with either Preview or adobe then save and it saves as a 789kb file.... hint hint.... I save the pdf to my idisk and open in any reader app on my ipad...

    NO CRASHING! it is truly the way safari is compressing the file not the pdfs fault but the browsers treated same pdf file differently...

    Safari is more compressed, Firefox is less...

    Try it!

    In looking at the Font cache on the Ipad Under System/Library/Fonts I see no Symbol.ttf font. WEIRD!

    Most of the pdfs I am viewing have this font embedded in them via viewing properties when saved under Adobe Acrobat Professional

    Secondly once I open the same pdf on my Mac Via Preview then Save it as PDF again the file gets larger. All the fonts change to True Type Embedded Subset fonts and the Symbol font is not longer there. The Metadata has also changed from the Adobe save vs. the Preview saved file.

    And the Preview Save file will open properly and not crash my Ipad!!!!

    So if you have this problem of PDFs crashing open them in Preview on your mac and resave them using preview then try to open them on your Ipad, regardless of viewer app.

    The ipad SDK for PDF viewing is not properly handling Adobe PDF metadata nor its embedded fonts.

    Apple you can contact me at mdrt4me@me.com for more info.

    This needs fixed ASAP.

    I had the same issue with medical journal pdfs. I followed the advice of opening and saving all the pdfs in preview app and saving them again. Interestingly the files doubled in size but now work fine.

    If yours are in single folder then go "select all" then "open in preview". You can then save each one to the same destination and just let it overwrite the original. Probably something to do with Adobe and Apple not talking to each other and downloads from safari being handled differently.

    Best of luck

    Where is on this. I am not having a good experience on this. Not to mention that I tried to put a serious ID in for this but my 4 letter name kept getting rejected because it wasn't between 2 and 30 cheracters. So, I winged it.

    Anyway, I am getting ready to go to Alaska on a trip and wanted to take some of the information about my camera and other equipment Rather than taking bulky manuals it ocoured to me, What a great use for my IPAD. I started loading the PDFs and keep coming up with one, so far, that keeps crashing the IPAD. It is the users guide by NIKON for the D200 DSLR. I, surprisingly, found another person who was having the exact same problem with the same manual but using the other PDF Reader. I am using PDF Reader PRO myself. Why would the other manuals go though fine and display fine but the D200 manual crash the IPAD. PLEASE, somoene post an answer.

    Thank You.

    I don't know if this will help, but i have downloaded large PDF files (150 page SEC filings like a 10K) on to a Windows PC and sync'd them to my iPad using Documents to Go, and they worked fine on my iPad.

    The one problem I am having is that I haven't figured out if you can save a PDF document you download directly to your iPad and then read it later. Right now it seems that if you download it using Safari, you can only read it through Safari, which requires you have WiFi/3G access...
