do you mean SWF convert to flash?
if yes, you can try about SWF decompiler.
It's an adobe file format for flash. SWF originated with FutureWave Software, and was initially called SWF for "shockwave flash"
Flash
SWF files are compiled animation file built using software. The most common software used is Adobe's Flash, but Adobe also offers several other software products that can output into the SWF format. There are also some open source implementations of Flash-like interfaces that work in a similar fashion. The SWF standard is not open, per se, but it has been made available by Adobe to allow for the creation of third party tools. A quick web search will bring up dozens.
Swf stands for Shockwave Flash It can also be Macromedia flash
.swf
I suggest that you download some special software like swf player or swf reader. I used to view swf files in Firefox.
swf is a flash file format.you can play it with a flash player.
If you attempt to open a SWF file from the Flash main program, the Flash Player will open them instead. If you mean can you import the SWF file into Flash, then that would depend on the security import settings on the SWF itself, that means that if it was designed with the option to protest it from omporting, then you can not. Otherwise, you can import the SWF, but you will only have all the frames loaded in one layer and will not be able to edit much from it except for whatever images were used.

No, the SWF file is a Flash player file. Any flash player can play it.
You can use a tool. I have used Flash Compression. It is easy to use, input a swf , the following the steps, your swf will be converted to exe. And according your needs, flash compression can optimizing the swf for you. You can also use an online coverter. The advantage is that you don't need to download or install any applications. You just open the site in your browser and select the swf file.
A 'SWF' is a flash-file. Flash is the program that runs Club Penguin. If you decompile Club Penguin, you'll find SWF-files, like rooms and catalogs.
