About This Tool
Base64 is an encoding scheme that converts binary data into ASCII text. It's commonly used in email attachments, data URLs, API authentication tokens, and embedding images in CSS or HTML.
This tool encodes and decodes Base64 entirely in your browser. No data is sent to any server. Supports full Unicode text including emojis and special characters.
