Choosing iCloud or Local Storage depending on your needs and considerations.

You can switch between iCloud or Local Storage at anytime but we don’t support moving data back & forth [But you can do it yourself by exporting and uploading to iTunes, then after switching the Storage, and then downloading from iTunes again]. To switch between iCloud and Local Store, open PDF Max and at the Library screen, tap the Settings icon at the bottom-right corner, then check or uncheck “Using iCloud” option (Your data won’t be deleted when switching).

That often happens at the first time you open a PDF document which is contributed by another device (if the connection is bad then PDF Max tries to download the document several times before informing you the file is not able to be downloaded) or if there are many annotations added by other devices then PDF Max merges all the changes from other devices each time you open a document. It is best to you use a fast Wifi network for heavily annotated and large documents. We provide the Background Sync option to tell PDF Max to automatically download your documents while you are using it [This only works while you're working with PDF Max, because iOS does not allow apps to be run in background, so PDF Max is only able to download when it is open].

Please note that the issue happens on iOS 5.x only, the upcoming iOS 6 resolved this issue.

If PDF Max is running slowly or is unresponsive, then force-quitting the app may resolve the issue.

If your PDF Max crashed often when you are working with large PDFs, then try to restart your device. If that doesn’t help then please contact us for support.

The Open In functionality is controlled by iOS, we have no active control over it, we just declare PDF Max to be capable of accepting PDF files. iOS is known to show only a limited number (10 or so) of randomly selected apps for any given file type when you invoke the Open In action in any app. The actual maximum number of apps depends on the device type and a version of iOS. The only way to resolve this issue is to delete some of the apps that expose themselves as handling PDF file types, perhaps those that you don’t need, in order to make room for other eligible apps such as PDF Max.

Yes, it does support unzipping .zip files when downloading from iTunes and Dropbox.

You can transfer PDFs into PDF Max in several ways: via iTunes File Sharing, importing from other apps, downloading from Dropbox, or via PDF Max’s built-in Web Browser. PDF Max supports unpacking zip files to help you transfer your whole library into PDF Max with minimal effort. In addition to importing PDF files, you can create a new blank PDF file within PDF Max.

To transfer your PDFs into PDF Max using iTunes, follow the steps below:

• Plug your iPhone or iPad into your PC or Mac.
• Open iTunes [for PC/Mac] application.
• Select your device at the left panel. Then choose Apps section at the top of the right panel.
• Scroll down and locate PDF Max on the application list under the Sharing Documents section and click to select.
• Drag your PDFs into the PDF Max Documents panel [at the  right. Wait for the copying progress completed.
• Now, start PDF Max app on your iPhone/iPad.
• In the Library view (where you see the Recent and Documents tabs at the bottom), tap the Plus button at the top-left corner, then choose iTunes under the Download Services section.
• In the iTunes download view, select the documents you want to import then tap Download button at the top-right corner of the view. Wait for the downloading progress completed then tap Close to return the Library.

Simply Tap and hold over any word to start the text selection mode. Please note that scanned PDF documents look like text but they are not and you can’t active the selection tool, in that case, to markup, use other tools such as Ink or Shape to draw over scanned PDF pages
