JPEXS Free Flash Decompiler (FFDec) is an open-source Java application for decompiling and editing Adobe Flash SWF files. It extracts resources, converts SWF to FLA, and lets users edit ActionScript, images, sounds, texts, and fonts.
Use cases
- decompile a flash swf file
- convert swf to fla source
- extract images and sounds from a swf
- edit actionscript inside a swf
- replace fonts and texts in flash files
- view swf file structure and resources
When to choose
- you need to inspect, decompile, or recover assets from legacy Flash SWF files
- you want to edit ActionScript or swap resources in a SWF without the original FLA
- you need a free cross-platform tool that runs on Windows, Linux, and macOS
When to avoid
- you are working with modern web animation formats instead of legacy Flash content
- you need a library to embed SWF decompilation into your own Java build pipeline rather than a GUI application
- you require commercial licensing or support guarantees
