Just like the popular Google Translate, Bing now offers online translation between various languages.
Visit Bing Translator and type in what is needed to be translated. The Auto-Detect feature works well by default but can be changed to specify a specific language as source. Hit “Translate” to view the translation.
For translating entire web pages, simply enter their links in source field. This may take a while though.
Also, a widget for Bing Translator is available which can be easily customized and added to blogs or websites if required. Get it from here.
