Introducing two PDF editor freeware, no installation, setup, pre-use learning, special skill or pricey software required.
(1) Free PDF Editor is capable to run in any USB flash drive, as the program size is as little as less than 1MB for version 1.3RC. It is as good as using a word processor to create a PDF output instantly, without the hassle to install PDF generator software.
(2) PDFTK Builder Portable is my favorite program to split, collate, watermark and password protect PDF documents on the go. As its name suggested, it is a proud portable application/freeware available from Portable Application as seen in PC World, PC Magazine etc. I have been carrying it in my USB flash drive all the time. Thanks to its GUI (graphical user interface) it is very handy and remarkably easy to use.
If you have better freeware to share, welcome to email to me or comment below this post.
