SWF & FLV Toolbox itself is a multifunctional SWF, FLV or EXE files to other formats converter. You can receive an output in AVI, JPEG, GIF, BMP, animated GIF or SCR formats. You can also convert FLV to SWF or make EXE file from original SWF or FLV video. As you perhaps know, EXE file doesn't need any player to be installed on the PC, it will play anyway. You can choose from two options in SWF & FLV Toolbox when making EXE: Standard or Advanced one.
SWF & FLV Toolbox features the option to convert one file or many files at a time, which helps to speed up the process significantly - just tell SWF & FLV Toolbox what to do and go take care of other things, while it is doing its job.
