PDFedit is a free PDF editor for Unix-like operating systems (including Cygwin on top of Windows). It does not support editing protected or encrypted PDF files or word processor-style text manipulation, however.

GoodReader is an iOS application used to primarily edit PDF documents. It was originally developed in Moscow by Good.iWare Ltd., a company started by Yuri Selukoff, a Russian developer. Yuri has subsequently relocated to the United States and started Good.iWare, Inc. in San Francisco, California.
