Persian (Farsi) language translation support has been added to Google Translate web service. Now you can translate any text, webpage, blog, message etc from English to Persian and from Persian to English with a click of a button using Google Translate. It is still in early stages and is not perfect as far final translated text is concerned.
If you understand Persian and see something incorrect or wrongly translated then use “contribute a better translation” to help Google Translate improve on it. As pointed by official blog, Google is also working on improving Persian translation for the additional 40 languages available via Google Translate. This for sure is welcome addition for users trying to access Persian language information in their own native language.
