Google Translate is pretty cool, but it works on web pages, not PDFs. What if you uncover a priceless PDF in, say, German, and you don’t sprechen sie Deutsch? Use Google Docs, of course. Lifehacker has this great tip – save and upload the foreign doc into Google Docs, click on Tools and then Translate and you will get a copy of the doc in your language of choice. It works with HTML, ODT, RTF, and DOC files. And, as Lifehacker reminds, you can always convert document formats within Google Docs – simply load the doc, open the File/Save menu, then Click Save As and choose RTF, PDF, HTML Word, or Open Office. Simple and effective. And, of course, Free. Doesn’t get any better.
