About This Tool
Base64 is a binary-to-text encoding scheme that represents binary data as an ASCII string. It is commonly used to embed images in CSS/HTML, encode email attachments, and transmit data in URLs or APIs.
This tool encodes and decodes Base64 strings entirely in
your browser using JavaScript's built-in btoa() and atob() functions
— no data is ever sent to a server.
