JPEXS Free Flash Decompiler
Decompile/ edit/ extract resources from Flash SWFs

JPEXS Free Flash Decompiler is an open source tool for decompiling Flash SWF files, extracting, editing or replacing their contents.

At a minimum you might use the program to grab images, videos or music from an SWF.

You could also tweak an applet, perhaps replacing a background image or the soundtrack. Flash developers might explore scripts to better understand how an applet works, or security experts can analyse a malicious applet to figure out what it's doing.

Whatever you're doing, the program is reasonably easy to use. There's no installation, and it's Java-based, so works almost anywhere: just open your applet and its various resources are displayed in a tree: shapes, sprites, buttons, fonts, frames, scripts and more. Expand a section like Sounds, then browse their contents, and right-click an item to view, remove, replace, export it and more.

JPEXS Free Flash Decompiler has plenty of other higher level functions. If you can't find an SWF file, it's able to search your browser cache, or even its RAM. And whatever you locate may be exported as a stand-alone EXE file, for easy playing on the Windows desktop.

Version 10.0 brings (Changelog):

  • Iggy Files support - reading and (limited) editation of fonts, texts and AS3 - 64 bit variant only
    optional AS3 direct editation with Flex SDK
    AS3 p-code editing - metadata read/write support
    AS3 p-code editing - end of the block command like in RABCDasm
    AS3 p-code editing - popup docs for more than instructions
    Debugger - New columns for variable details - scope, flags, trait
    Debugger - Add watch feature
    AS3 decompilation - colliding trait/class names handling - show hash suffix with namespace index on such cases
    Deobfuscation Tool - Fix colliding trait/classes via toolbar command
    Auto rename identifiers option now fixes colliding trait/classes aswell
    Issue #1254 FLA export - detecting scripts on AS3 timeline
    Issue #907 FFDec Library JAR file has version inside it.
    Issue #1311, Issue #1313 actionScript source font size
    Display warning when library version and GUI version mismatch
    Changelog file


JPEXS Free Flash Decompiler is a powerful application with a stack of essential features, yet remains accessible - and very useable - to non-developers.

WhatsApp Messenger 2.17.42

Free Full Commercial Software

WhatsApp Messenger is the world's most popular instant messaging app for smartphones.

You can use it to send and receive text and voice messages, photos, videos, even call your friends in other countries, and because it uses your phone's internet connection it might not cost you anything at all (depending on whether you'll pay data charges).

It's easy to set up and use. There's no need to create and remember new account names or pins because it works with your phone number, and uses your regular address book to find and connect you with friends who use WhatsApp already.

You can talk one-to-one or in group chats, and because you're always logged in there's no way to miss messages. Even if your phone is turned off, WhatsApp will save your messages and display them as soon as you're back online.

There's plenty more (location sharing, contact exchange, message broadcasting) and the app is free for a year, currently $0.99/ year afterwards.

What's New in Version 2.17.42

• Pin chats to the top of your chat list, so you can quickly find them. Just swipe right on a chat and tap the pin icon.
• You can now send documents of any type. To send a document, open a chat, tap attach — document. 
• When you receive multiple photos, you can now tap and hold on the group of photos to quickly forward or delete all of them.
