Base64 Encoder & Decoder
Encode text payloads or decode Base64 strings safely in your browser with full UTF-8 character support.
How to Use the Online Base64 Encoder & Decoder
Base64 is a binary-to-text encoding format that represents 8-bit binary data as a sequence of 64 ASCII characters. It is commonly utilized across software systems to transmit data over media channels designed strictly for textual data. To convert your text payload, choose either "Base64 Encode" or "Base64 Decode" mode above, paste your input into the text box, and copy the calculated result instantly.
When working with Web APIs, authorization headers, or configuration files, Base64 encoding guarantees that special characters, line breaks, and punctuation remain intact without being corrupted during transmission over network proxies or email servers. Our utility includes native UTF-8 multi-byte encoding support, ensuring smooth translation for international character sets and modern emojis.
Zero Server Uploads & Complete Confidentiality
Many online converter tools transmit secret keys or authentication tokens to remote servers. At Codify Tools, your data never leaves your browser. All encoding and decoding operations execute inside client JavaScript memory, preserving complete privacy for API credentials, JSON tokens, and proprietary strings.
