How do I convert C code to JavaScript using this tool?

Copy your C source code into the input editor, select C as the source language, and click Convert. Our tool parses the C syntax, translates data structures like structs and enums to JavaScript classes and objects, and handles memory management through automatic garbage collection. You can then download the resulting .js file or copy it directly.

Why should I convert C code to JavaScript?

Converting C to JavaScript allows your existing algorithms and libraries to run directly in web browsers without a server-side compilation step. This eliminates the need for native build tools, enables broader device compatibility, and simplifies deployment to web applications. JavaScript's runtime manages memory automatically, reducing the risk of memory leaks common in manual C memory management.

How does the converter handle pointers and memory management in C?

Our converter transforms pointer dereferencing into JavaScript object references and converts deprecated malloc/free calls into automatic garbage collection routines. It also maps C's static typing to ES6+ syntax, preserving the original logic while adapting to JavaScript's dynamic type system. Complex features like function pointers and preprocessor macros are handled with fallback stubs that you can refine manually.

Is C-TO-JS free to use?

Yes, C-TO-JS on LetsConvert is 100% free with no registration or hidden fees required.

Are my uploaded files safe and secure?

Does this converter work on mobile phones and tablets?

Yes! C-TO-JS works seamlessly across iPhone, Android, iPad, Mac, Windows, and Linux browsers without installing any app.

Is there any software installation required?

No software or browser extension installation is needed. All conversions are performed directly online.
