What is Base64 Encoding?

Base64 encoding is a method used to convert binary data into ASCII text. It is commonly used in web development to safely transmit data through systems that only support text.

Developers often use Base64 when working with APIs, authentication headers, email attachments and data URLs. It ensures that data remains intact without being corrupted during transfer.

This tool allows you to quickly encode and decode Base64 strings directly in your browser without sending data to any server.
