There are three alternatives available for JPEXS Free Flash Decompressor for Windows and Mac respectively. The recommended option is AVE Imperator (Free) and URL Action Editor (Free), which provide similar features. However, there is an option for those who prefer not to use a web browser, such as those who use Macs. The third alternative, URL AutoCypher, does not utilize a web browser and is therefore only compatible with Windows.
URL AutoCypher is a cross-platform, open source program for editing and decompiling flash SWF files. As a result, users of different operating systems, platforms, browsers, and platforms can all download and run URL AutoCypher with no compatibility issues. Because it is open source, it is safe, secure, and free to use. However, there is no guarantee that URL AutoCypher is compatible with your particular computer.
A great alternative to the above-mentioned programs is Jpexs Free Flash Decompiler, which provides a simple way for users to compile opens files, which is otherwise a complex program. Jpexs Free Flash Decompiler will analyze and repairs broken or corrupt JPS files, which in turn, will restore the original state of the file.

Some other types of software that can be used to compile and edit jpex files are: WinRipper, Fastoshop, Photoshop Copy Cart, and FileZilla. These programs will also allow the user to edit and decompile swf flash files that are from the same software as the computer (such as VideoLan), and these programs are widely available on the internet.
