# Disassembler for ARM, x86, WebAssembly, .NET, and Java — in a Single HTML File
 🇬🇧 English ·
 🇷🇺 Русский 
**A cross-platform disassembler that runs entirely in your browser — offline, with no installation or uploads.** Open a native executable, shared library, WebAssembly module, .NET assembly, Java class, or application archive and explore its instructions, functions, references, strings, and binary metadata.
Everything fits into **one self-contained HTML file**: `build/disassembler.html`. Open it from your disk in a modern browser. Files are processed locally, and the page's Content Security Policy blocks network access.
### Supported formats and architectures
| Platform or runtime | Formats | Architectures or bytecode |
| --- | --- | --- |
| macOS | Mach-O executables, `.dylib`, universal binaries | arm64, arm64e, x86-64, i386 |
| iOS | Mach-O, `.ipa`, zipped `.app` | arm64, armv7 |
| Windows | PE `.exe`, `.dll` | x86-64, i386, arm64, ARM64EC, ARM64X, 32-bit Arm |
| Linux | ELF executables, shared libraries | x86-64, i386, arm64, 32-bit Arm |
| Android | ELF `.so`, `.apk`, `.aab`, `.apks`, `.xapk` | arm64-v8a, armeabi-v7a, x86_64, x86 |
| WebAssembly | `.wasm` core modules | WebAssembly instructions |
| .NET | Managed `.exe`, `.dll` | CIL (C#, F#, Visual Basic, and other CLI languages) |
| JVM | `.class`, `.jar`, `.war`, `.jmod`, `.aar` | Java bytecode (including code compiled from Kotlin and Scala) |
Explore decoded instructions in assembly notation, with explanations and instruction statistics. For **arm64, x86-64, WebAssembly, .NET, and Java**, you can also switch to a more readable **HLA64** representation. HLA64 is an assembler with higher-level syntax for ARM64, x64, and WebAssembly; this project also extends its notation to CIL and JVM bytecode.
### Try it
**Open the online PWA** — install it as an app or use it in your browser. After the first visit, it can run offline. Files are still opened locally and are never uploaded. On desktop Chrome, Edge, or Arc, use the browser's install option; on iOS, use **Share → Add to Home Screen**.
**Download a standalone HTML file** — each release includes `disassembler- .html` and `SHA256SUMS.txt`. Keep the file on disk and open it without an internet connection. Unlike the PWA, the downloaded file remains on the version you chose.

### Examples
 [code] 
The Android armeabi-v7a build, with Thumb-2 and one A32 file, opened directly from the APK
(stripped; the tool distinguishes T32, A32, and data through code analysis):

## Getting started
1. Run `./build.sh open`, or run `npm install && npm run build` and open `build/disassembler.html`.
2. Click **Open a program**, or drag a file onto the page. An app's program is inside its bundle:
 `Name.app/Contents/MacOS/Name` (in the Finder: Show Package Contents). Universal files open at
 their arm64 slice; the **Mach-O** page opens the others (x86_64, an
