PDF Studio is an easy-to-use yet powerful tool to work with PDF documents. It can work with existing PDF documents or you can create new documents from scanned images using the scan-to-PDF feature. With PDF Studio, you can annotate your documents with text, graphics and even sound. You can fill interactive pdf forms, stamp documents to mark them as Confidential, Paid or Urgent and perform other functions such as splitting and merging, setting passwords and more. You can also work on multiple documents with a single click using batch functions. PDF Studio uses Qoppa's proprietary technology to view and modify PDF files so there's no need to purchase Adobe Acrobat or any other software.
