JavaScript Protection Platform
Protect production JavaScript without slowing your team down.
JavaScript Obfuscator helps you harden source code against reverse engineering, copying, and tampering with both desktop workflows and a fast online obfuscator.
ECMAScript Ready
Modern syntax, modules, async flows, and current JavaScript tooling.
Desktop + Web
Use the browser for speed or desktop app for repeatable project jobs.
Flexible Plans
Start free, then scale quotas and file capacity as your usage grows.
Protection Preview
Readable in, protected out.
See how quickly clear application logic turns into difficult-to-reverse protected output.
Input
function validateLicense(plan) {
if (plan === 'trial') return false;
return plan.expiresAt > Date.now();
}
Protected
function _0x7f1a(_0x2a9d){
return _0x2a9d!==_0x57('trial')
&& _0x2a9d[_0x57('expiresAt')]>Date.now();
}
Batch processing
Protect complete projects in one pass with the desktop app.
Embedded JS support
Secure JavaScript inside HTML, PHP, ASP, ASPX, and JSP files.
Layered hardening
Combine mangling, encoding, compression, and locking options.
Fast Start
Paste code into the online obfuscator and ship protected output in minutes.
Great for experiments, demos, and one-off jobs.
Desktop Control
Move bigger workflows into the desktop app when you need repeatable project protection.
Ideal for embedded JavaScript and bulk processing.
Safer Releases
Reduce exposure of business logic, licensing checks, and proprietary front-end code.
Built to preserve behavior while increasing resistance to inspection.
Built for Real Projects
Turn readable source code into protected output that is much harder to analyze, while keeping your application behavior intact and your release process practical.
- ✓
Make logic, identifiers, and strings significantly harder to follow in shipped bundles.
- ✓
Reduce JavaScript payload size while adding protection, so you are not choosing between security and performance.
- ✓
Use the desktop workflow to protect JavaScript embedded in server-rendered templates and mixed files.
Why Teams Choose It
The homepage now points clearly to the same story: protect code, preserve behavior, and move from one-off use to team-scale workflows without friction.
Transform readable JavaScript into output that is much harder to understand, reuse, or modify.
Reduce JavaScript payload size and help applications load faster while adding protection to shipped code.
Designed to preserve runtime behavior while reducing exposure and supporting modern ECMAScript.
Add stronger protection with domain restrictions, trials, and additional release controls.
Protect full projects quickly, including JavaScript embedded in HTML and similar files.
A mature workflow used by teams that need dependable JavaScript protection in production.
How It Works
Whether you start in the browser or the desktop app, the workflow is straightforward and designed to be repeatable.
Use the online obfuscator for speed or the desktop app for larger project batches and embedded JavaScript.
Combine obfuscation, mangling, string encoding, compression, and locking options based on your release needs.
Deploy output that keeps application behavior intact while making client-side logic harder to inspect and reuse.
