JEB Decompiler

Reverse engineering is a complex and lengthy task. Use the right software for the job and cut down on expensive man-hours.

JEB is a modular reverse engineering platform for professionals.

Perform disassembly, decompilation, debugging, and analysis of code and document files, manually or as part of an analysis pipeline. Use JEB to analyze Android apps, reverse engineer Windows malware, audit embedded code, and much more.

The Android modules for JEB provide static and dynamic analysis capabilities to analyze Android applications, goodware or badware, small or large.

The native code analysis modules provide advanced code analyzers and decompilers for Intel x86, ARM, MIPS, RISC-V processors, as well as WebAssembly modules and Ethereum smart contracts

Our PDF module for JEB can be used to manually or automatically reverse engineer and assess PDF documents.
