Are you serious about hex editing and binary file analysis?

Do you know how frustrating and annoying it can be to use a regular hex editor?
You have to keep in mind the meaning of all the bits and bytes while crawling through the file.
And every time you look at a file you start anew this tedious process.

Stop wasting your time and let your Mac do the work.

With Synalyze It! Pro you can
* define a "grammar" that contains all the knowledge about a file format
* decode files automatically using this grammar with the Universal Parsing Engine
* make assumptions in unknown file formats and record them in a grammar
* save tons of time by using free grammars for well-known file formats like ZIP, JPEG, PNG, ICC or OpenType
* reveal the secrets of proprietary formats
* learn reverse engineering of binary files
* process the parsed file contents with Python or Lua scripts
* analyze files with powerful features like histograms

Synalyze It! Pro is a real breakthrough in binary file analysis - a modeling tool for binary files.

And by the way: it's a great hex editor, too :-) The Hex Editor you'll love!

Updated, finally!

Thank you! I rarely use Synalyze It!, but when I need it, it's a super useful tool. It wasn't updated for the longest time. I though tthe author abandoned it. I even looked to see if I could contact him online, but couldn't find a way to do so. I'm so glad he's okay and that he now updated this.

Loved before but crashing now....

I updated to MacOS 12.3 and now this crashes when trying to open. I checked the system requirements before and saw it needs MacOS 10.9 or greater, but now on deeper review, it is known to not work with 12.3... So much for trying to research and plan upgrades. Please get it working again.... It was a great program when I could use it.
