Synalyze It! is a simple to use Mac OS X app which lets you easily edit and analyze binary files of any size. It's the little brother of Synalyze It! Pro but still much more than a regular hex editor.

Synalyze It! features enhanced support for many character encodings and it will allow you to interactively define "grammars" for various file formats. Several grammars do already exist and can be downloaded for free. Files are decoded automatically using grammars!

Synalyze It! is perfect for editing saved games or other unknown binary file formats and actively supports reverse engineering.

Here are some key features of Synalyze It!:
* Hex Editor & Viewer (change, insert and delete quickly in files of unlimited size)
* Printing
* Histogram view
* Go to Position in file
* Save selected bytes
* Compare code pages
* Incremental text search with encoding selection
* Find text
* Find numbers
* Search for masks
* See all strings in a file

Great - but needs ONE MORE THING to make it the VERY BEST.

The thing that would put this over the top is HEX COMPARISON. I love the hex editor part but I get sad when I see that we can compare, yet not compare IN HEX. I would gladly pay for this feature (premium version?) because this is so...awesome.

Anyone that doesn't need the above HAS to download this right now. Fast, free, easy binary editor/comparer (except hex... :( )

Did not work as shown in tutorials

Most of the features are missing. You can’t apply grammars and the tutorial directions on the website do not work. Dropdown menus are different and are missing the option to insert, which you need in order to apply/create a grammar.

Developer Response ,

Thank you for the feedback! While I understand that it's frustrating when software doesn't work as expected I'd appreciate if you could describe me in an email briefly what exactly didn't work or is missing - .

With this application it should be possible to apply all grammars and do the same what's described in the tutorials. I'm confident we can make it work also for you.

Massive Time Saver

I've used Hex Fiend for years and still a fan, but this tool wins hands down! Keep up the great work!

Thank you for the positive feedback! Synalyze It! was built to be a time saver in reverse engineering and file analysis tasks.
