What Is Base64 Encoding?

Base64 encoding converts data into a text-based format using letters, numbers, and a few symbols. It is commonly used when data needs to be safely stored or transferred through systems that handle text better than raw binary data.

Developers often use Base64 for API testing, basic authentication strings, encoded URLs, small data snippets, configuration values, email content, and web development tasks. It is important to remember that Base64 is reversible, so it should not be treated as a security method.
