Frequently Asked Questions
What is an AI code converter and how does it work?
An AI code converter is an online tool that translates source code from one programming language to another. CodeConvert AI reads your original code, interprets its logic, structure, and intent using large language models, and generates equivalent code in the language you choose. Paste your code, select the source and target languages, and click Convert to get a translation in seconds.
Which programming languages can I convert between?
The converter supports 60+ programming languages, including Python, JavaScript, TypeScript, Java, C#, C++, C, Go, Rust, Ruby, PHP, Swift, Kotlin, Scala, R, MATLAB, Perl, and Lua. You can translate between any combination of supported languages, in either direction.
How accurate is AI code conversion?
The AI preserves the logic and functionality of your original code and handles common patterns, data structures, and language-specific idioms. Straightforward functions and algorithms usually convert cleanly. For large, complex, or performance-critical code, review and test the output before using it in production, since no automated converter is 100% accurate.
Can I convert a whole file or program at once?
Yes. You can paste an entire file or program and convert it in one step. Anonymous use supports up to 4,000 characters of input per conversion; signing in for free raises the limit to 25,000 characters per conversion for larger files.
Is the code converter free, and do I need to sign up or install anything?
The code converter is free and runs in your browser with nothing to install. You can convert code without an account for up to 5 conversions per day. Signing in is free and gives you 5 credits with higher input limits.
Is my code kept private?
Your code is sent securely to the AI model only to perform the conversion, and it is not sold or shared. As with any online tool, avoid pasting secrets such as API keys or passwords. For sensitive projects, review our code privacy policy before converting. Read our code privacy policy
