Sometimes a client might give you a file saved in an exotic format. You don't have the program required to open it, nor are you inclined to install it for this one instance. Now you don't have to — Zamzar allows you to upload your file and save it as something openable. In my case, I tested the service by uploading a Microsoft Publisher file and saving it as a Word Doc. Seconds later, the converted file was in my inbox. The basic service is currently free, with a paid service allowing online file storage and faster processing. The name of the service derives from the protagonist of Franz Kafka's The Metamorphosis.
