Encode and decode Base64 and URL text quickly and easily.
Our Base64 Encoder is an essential tool for converting plain text into Base64 encoded format, commonly used for transmitting binary data over text-based protocols. Base64 encoding transforms binary data into a safe ASCII string, making it ideal for embedding images in HTML/CSS, sending attachments in emails, or securing data in transit. The tool handles any text input, including special characters and Unicode, producing a clean, encoded output that's compatible with various systems. Whether you're a developer working with APIs, a web designer embedding assets, or anyone needing to encode sensitive information, this encoder provides fast, reliable results with no data transmission.
The Base64 encoding process uses PHP's built-in base64_encode function, which converts the input string into a Base64 representation. The algorithm groups binary data into 6-bit chunks, mapping each to a character from the Base64 alphabet (A-Z, a-z, 0-9, +, /). Padding with '=' ensures proper length. The entire process occurs server-side for security, with input validation to handle edge cases. Encoded output is immediately available for copying or use.
Your data's privacy is fully protected. Encoding occurs locally on the server, with no external transmission. We don't store, share, or analyze your input. The tool operates without user accounts, ensuring complete confidentiality for encoded content.
