Questions fréquentes et réponses
Will minifying JavaScript change how my code runs?
No. As long as your original code had proper semicolon termination, minification preserves exact execution behavior.
Are my files uploaded, analyzed, or stored on NexVaani servers?
Where supported, tool inputs and files are processed locally inside your web browser using WebAssembly and HTML5 Canvas. Your files are not uploaded to NexVaani file-processing servers.
