A few months ago I thought I had found a site that talked about uploading old worksheets and being able to convert them to google docs with the ability to add text. I tried to take a pdf and open it using Google docs and then add text boxes to the worksheets but I couldn't overlay the text boxes on the images.
Does anyone have a work around for taking pdf documents and making them editable?
Have you tried any of the Pdf apps/extensions like pdf zen or PDF escape? They allow you to write on and edit pdfs. Another option is to convert them using a computer by using adobe acrobat - you could download a 30 day trial and upload thos to docs.
