The main purpose of a digital signature is to uniquely identify the signer of an electronic document. With the advent of paperless business models there is an increased demand for digitally signed PDF documents. In many countries digitally signing an electronic document became a legal requirement.

Neevia PDFsign/encrypt is a cost effective application that allows you to digitally sign, timestamp and/or encrypt PDF files. By applying a digital signature on your PDF documents you will be able to guarantee the integrity of the content and also provide an additional level of trust in any business transaction you conduct. If you are a developer you can easily integrate PDFsign/encrypt with your own application via a COM object or .NET assembly.

Key features:
  • Sign multiple PDF files in one step;
  • Time-stamp PDF files;
  • Certify PDF files;
  • Flexible signature appearance;
  • Fully multi-threaded
  • Linearization (Fast Web View) support;
  • PDF encryption support (RC4/AES algorithms);
  • Does NOT require any Adobe products;




  • Unlike other similar PDF tools neeviaPDF applications come with a command line tool, a graphic interface application, COM Object and .NET assembly, all in one package for one low price.
