Apple decided that it would no longer need iWork.com back in March to share documents and instead will just push the service to iCloud. As a reminder, after July 31 2012 you’ll no longer be able to publish any documents to the website nor access any previously uploaded documents. As mentioned previously, iCloud will be able to solve your problems as it will allow you to share and upload any documents from your Macbook or iOS device.
To save all of your documents, you’ll need to go to iWork.com and download all of your documents that are currently on the website. Apple mentioned that you should try to do this as early as possible. Go to the Shared Documents page while on the website and then select the download arrow with the documents you wish to maintain from the site. You can download the documents in three formats: iWork ’09, Microsoft Office, or PDF. The shutdown of iWork.com goes along with the shutdown of MobileMe, Apple’s previous backup cloud solution its iOS devices. This has also been absorbed into iCloud.RELATED
