Perguntas frequentes

Quick answers.

›What is an ArrayBuffer?

An `ArrayBuffer` is a generic fixed-length raw binary data buffer. It cannot be manipulated directly; instead, you use a TypeArray or DataView to read and write the underlying content.

›Does this tool work with files?

This tool is designed for small to medium byte strings and arrays. For very large files, your browser may experience performance lag during the conversion process.

›Is my binary data secure?

Yes. All conversion logic is executed locally using JavaScript. No data is transmitted to an external server, ensuring your keys or sensitive payloads remain private.

›Why use Hex instead of Base64?

Hexadecimal is often easier for humans to read and debug as it maps directly to byte boundaries. Base64 is more compact for transmission, reducing data size by approximately 33% compared to hex.
