Google Earth, the Chrome browser and photo service Picasa will be available for download in Iran for the first time, the search giant has announced.
It follows an easing on US export restrictions to the country last year.
One of the conditions of the licence is that none of the products can be downloaded by or on behalf of the Iranian government.
Google says it is hopeful the new tools will enable freer communication in the country.
“There are many activist layers on Google Earth. Anyone can create a layer to show exactly what is going on in Iran,” said Google’s head of public policy Scott Rubin.
