How do I edit a pdf file from my teacher to enter text or images?

Hi,

You can convert the PDF files to Word, Excel or PowerPoint format  then edit the files within MS Office applicaiton(Some PDF file cannot be exported to those formats due to the security settings). Adobe ExportPDF service is available for exporting PDF files to those formats.

Please see more information for ExportPDF at https://www.acrobat.com/exportpdf/en/home.html?trackingid=KFWEH

Adobe Acrobat applicaiton can edit some text and images and please see more informaiton at http://www.adobe.com/products/acrobat/editing-pdf-documents.html.

We have a new service called Acrobat Plus to use Acrobat XI Pro and see more information at https://www.acrobat.com/acrobatplus/en/home.html

Thank you.
