Pidgin Portable is the versatile Pidgin instant messaging client packaged as a portable app, so you can take your IM settings and buddy lists with you.

Pidgin is a multi-protocol instant messaging client compatible with AIM (Oscar and TOC protocols), Yahoo, ICQ, MSN Messenger, Gadu-Gadu, IRC, Jabber and Zephyr networks.

Pidgin users can log in to multiple accounts on multiple IM networks simultaneously. This means that you can be chatting with friends on AOL Instant Messenger, talking to a friend on Yahoo Messenger, and sitting in an IRC channel all at the same time.

Pidgin Portable has all the same great features as Pidgin, including support for AOL, Yahoo, MSN, ICQ and Jabber networks, but there's nothing to install on the local PC. You can also easily add portable encryption plugins for secure, encrypted messaging.

The license of this software is Freeware, you can free download and free use this instant messenger software.
