Free Android app allows you to save any format Gmail attachment

Luckily, Poofinc Studios has come to the rescue with a free app called Gmail Attachment Download. The title of the app is pretty self-explanatory. It allows you to download any type of attachment from Gmail and save it anywhere you want to, be it the internal memory or the SD card.
It is ad-supported, free, and works with other e-mail clients. You can grab a copy of Gmail Attachment Download right now in the Google Play store.
