Why Use Base64 Encoding?

Base64 encoding is essential for transmitting binary data across systems that only support text content. It's widely used in web development, email systems, and data storage where binary data needs to be represented as ASCII text. Our tool provides a simple and secure way to perform these conversions with support for multiple file formats and instant results.
