A QUICK EXPLAINER
What is Base64?
Base64 is a way to represent binary data using a set of 64 printable characters. It is commonly used to safely carry data in email, URLs, and text-based formats such as JSON or XML. It is an encoding—not encryption—so it should never be used to protect sensitive information.
