BASE64
CODEC
High-fidelity binary-to-text encoding. Optimized for data transmission across systems that only support text.
Documentation // Base64 Encoding Standards
Base64 is a group of binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. It is most commonly used when there is a need to encode binary data that needs to be stored and transferred over media that are designed to deal with text.
Our Online Base64 Decoder ensures that data integrity is maintained during transport. This is essential for Data URIs, embedding small images in CSS, or passing complex strings through URL parameters.
URL-Safe Base64: Standard Base64 uses + and / characters, which have special meanings in URLs. Our URL-Safe Encoder swaps these for - and _ respectively, eliminating the need for further URL encoding.
UTF-8 Support: Standard JavaScript btoa() does not support Unicode. Our algorithm uses a robust UTF-8 character escape sequence to ensure that emojis and non-Latin characters are encoded and decoded without data corruption.
