About Decompiler.com

Decompiler.com is a free online decompilation tool for software developers, security researchers, and students. It allows you to upload compiled artifacts and view their decompiled source code directly in your browser — no installation required.

Supported Formats

• Java: JAR, CLASS, ZIP files
• Documents: PDF page previews, text, images and attachments
• Android: APK, XAPK, DEX, ARSC files
• .NET: EXE, DLL files compiled for .NET
• Python: PYC, PYO bytecode files
• Lua: LUAC compiled Lua files
• SourceMod: AMXX and SMX plugin files
• Valve game assets: VPK extraction and Source 2 asset decompilation

Intended Use

This tool is designed for legitimate purposes, including:

• Interoperability analysis — understanding how software works to build compatible tools and integrations.
• Debugging — diagnosing issues in compiled libraries when source code is unavailable.
• Recovering lost source code — retrieving source from your own compiled artifacts.
• Education — learning how compilers and software work by examining compiled output.
• Security research — analyzing software for vulnerabilities and malware.

How It Works

Upload your file, and our service will automatically detect the format and apply the appropriate decompiler. Results are available within seconds for most files. For larger artifacts, you can browse partial results while decompilation continues in the background.
