常见问题与解答
Why should I encode HTML special characters?
Encoding prevents browsers from interpreting raw characters as HTML tags, preventing layout breaks and XSS security vulnerabilities.
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.
