We’ve been discussing PDF documents at school recently and the difficulties manipulating information contained within. Download Squad have posted about a free download that converts PDF documents to Word format. I tried it out tonight. It was easy to download and the conversion was quick. In less than 20sec a large PDF file was available as a Word document that could be edited. Our interactive whiteboards save data as a PDF – this could be a very helpful free tool for teachers who want their students to be able to edit documents.
