Fastest Decompiler

JustDecompile is fast. In fact, really fast. When tested against the leading competitors, for .NET framework decompilation time, JustDecompile came out 10 times faster than the leading commercial decompiler. Try it and verify the results for yourself.

Extensible

The JustDecompile API is open to the community. This means you can create your own JustDecompile extension and we will promote it in the growing Telerik community of 1,000,000+ developers. Among the extensions: Reflexil, for assembly editing and De4Dot, for deobfuscating obfuscated assemblies. Browse all available extensions on the <a href="http://www.telerik.com/products/decompiler/extensions.aspx">Extensions Page</a>. The JustDecompile Plugin Manager lets you easily download and administer your extensions right inside JustDecompile. You can download, install, uninstall, enable, disable, read license agreements or directly go to each plugins&rsquo; official website without ever exiting the JustDecompile UI.

Easy Assembly Management

JustDecompile quickly loads the core framework assemblies for .NET 2.0, .NET 3.5, .NET 4.0, .NET 4.5,&nbsp;.NET 4.5.1. .NET 4.5.2, .NET 4.6, .NET 4.6.1, .NET 4.6.2, .NET 4.7, .NET 4.7.1, WinRT Metadata and Silverlight. Loading the assemblies you want to browse is simple. Create your own custom Assembly Lists so that you don&rsquo;t have to load the same assemblies over and over again. JustDecompile is following all new developments in the .NET world. JustDecompile supports the new version of C# and the Windows Runtime cross-platform application architecture on Windows 8 (WinRT). Alongside WinRT support, JustDecompile now supports two new file formats APPX (which is used for packaging Windows 8 apps) and WinMD (WinRT meta data files). Plus, the Silverlight XAP decompilation works from both your local file system and the web.

Fast Code Navigation

The JustDecompile robust search method, quickly navigates to the code of interest. With the addition of Full Text Search, the search is even more comprehensive. Dialogues help you navigate to code symbols and types. Simply type the name of the object you&rsquo;re looking for, or take advantage of the CamelCase search.

Creates Visual Studio Projects

JustDecompile can create a Visual Studio project from a decompiled assembly. Export lost projects or obtain multiple classes without the need to copy and paste code. So you&rsquo;ll never lose another project again.

One Engine, Three Tools

Combined with <a href="/products/justcode.aspx">JustCode</a>, JustDecompile allows you to decompile and navigate to code in project references. Plus, JustCode now offers the option to <a href="http://blogs.telerik.com/Skimedic/posts/13-06-17/debug-decompiled-code-with-justcode">debug decompiled third party assemblies</a> without ever leaving Visual Studio. Combined with <a href="/products/memory-performance-profiler.aspx">JustTrace</a>, JustDecompile will enable you to examine the source code of functions, you&rsquo;re profiling, right inside JustTrace even if the source code is not available.

View Decompiled Code in Tabs

With the JustDecompile tabs you can easily switch between different methods and assemblies in one JustDecompile instance. Easily see and compare the decompiled code of two different methods without leaving the user interface of your current JustDecompile instance.

Visual Studio Extension

You can decompile referenced assemblies in a Visual Studio project with the help of a JustDecompile context command, right from the Solution Explorer. Supported Visual Studio versions: 2010, 2012, 2013, 2015 and 2017.&nbsp;

Extract Resources From Assemblies

You can save resources from assemblies by right clicking on the desired resource and saving it.

Usage Analysis

The Find Usages features will bookmark the usages of the currently selected code symbol in any of the loaded assemblies.

Command Line Support

JustDecompile has the ability to export code directly from the command prompt. For ease of use you can add <strong>%PROGRAMFILES(X86)%\Telerik\JustDecompile\Libraries</strong> to your Path environment variable.&nbsp; To generate the Visual Studio project for an assembly from the command prompt, use the command <strong>JustDecompile.exe [/lang:csharp] /out:</strong><strong>[OutputDirectory] /target:[PathAndAssemblyName].</strong>

Integrate With Windows Explorer Context Menu

<p>The JustDecompile Explorer context menu allows you to decompile an assembly after browsing to it in Windows Explorer, without having to open JustDecompile from the start menu.</p>

Testimonials

Telerik JustDecompile is a fantastic tool. It is one of my go-to tools that I use as a software and build release engineer. I love that it will create the source and even generate project code if you want. Thanks for making this awesome tool and keeping it free.

I've used the Telerik JustDecompile tool and it is fantastic. I was able to retrieve all the source code from a website my client no longer had access to. I recommend this product to any developer that needs to decompile and retrieve source code.
