No. The optimizer aims to preserve the exact same output/behaviour while improving the internal implementation. We always recommend reviewing the changes.

The optimizer aims to produce functionally equivalent refactored code: code that produces the same outputs for the same inputs while being written more clearly or efficiently. Always test the optimized output against your existing test suite before deploying. The optimizer explains each change it makes, so you can review and reject any suggestion. For understanding what the original code does before optimizing it, the AI Code Explainer gives you a plain-English breakdown first.

Optimization focuses on readability and logic efficiency. If you strictly want to remove whitespace to reduce file size, use our Minifier tool instead.

We process your code for the duration of the request and do not store it permanently. Your intellectual property remains yours.

Code you submit is processed to generate the optimization suggestions and is not persistently stored or shared. It is not used to train AI models. Your proprietary algorithms, business logic, and internal implementation details remain private. After optimizing, use the Code Formatter to apply consistent indentation and style, and the Comment Remover to strip any outdated inline comments before adding fresh documentation.
