Base64 Encoder/Decoder
Convert text to Base64 encoding and decode Base64 strings back to readable text. Essential for data encoding, API integration, email attachments, and web development. Supports Unicode characters and handles large text inputs efficiently.
About Base64 Encoding
Base64 is a widely-used encoding scheme that converts binary data into ASCII text format. It uses 64 printable characters (A-Z, a-z, 0-9, +, /) to represent data, making it safe for transmission over text-based protocols like HTTP, email, and JSON.
Common Uses: Web development (data URLs, embedded images), email attachments, API data transfer, storing binary data in databases, URL-safe data encoding, and configuration files.
Important: Base64 is encoding, not encryption. It increases data size by ~33% and provides no security. Anyone can decode Base64 text using tools like this one.
