ChromeOS recovery images come in a .zip file.

You will need:

Recovery images have a code name associated with them also referred to as the board name.

To find your board name visit the website chrome://version and find the line labelled Firmware Version. It will look something like Google_Reks.7000.100.100. Your Chromebook's firmware version is the word after Google_ and before a period.
