J2K represents an upgrade of the JPEG format, including more features, such as supporting transparency and alpha channel, or lossless compression. J2K is part of a larger pack of improved JPEG extensions, known as JPEG2000, together with formats such as J2C, JPX, JPM or JP2. Most of these formats are compatible with mainstream image viewers, but do not enjoy the popularity of JPEG.
SWF (Small Web Format) is a multimedia and vector graphics format initially created by FutureWave Software, then later on transferred to Macromedia and currently owned by Adobe. SWF files contain animations and sound, developed so as to be easily uploaded and shared on the web. They can also include certain interactive programs, such as browser games, and can be opened using a Flash plugin.

Go to the Saving options tab and decide where you want to save new .swf files. You can also spend a few more moments to apply additional editing to the images prepared for conversion.
Select SWF as Output Format
Then pick the SWF as output format. To help you do this, a series of buttons is conveniently placed at the bottom of the reaConverter window, so you can simply press on the one you need or click Plus button to add new options.
Then simply press the Start button and your conversion will begin in no time!
