What is a Base64 Encoder & Decoder?
Base64 is a group of binary-to-text encoding schemes that represents binary data in an ASCII string format.

This tool lets developers quickly transform plain text into Base64 format and vice versa.

Why is Base64 encoding used in web development?
It is often used to inline small image assets, embed binary data into HTTP requests, handle web authentication headers, and safely pass complex parameters in URLs.
