[v7.00, v4.xx] PicoPDF – Easily edit your PDF documents

PicoPDF (AKA: PicoPDF PDF Editor) is a small, easy-to-use and full-featured PDF editor for Windows and Mac platforms, developed by NCH Software from Australia. The first time you use it, you will seriously doubt whether it really works. Because for a PDF editor that only has a 1M+ file size and does not rely on any components such as .NET, it's harder to implement than a PDF reader.
