Base64 Encoder & Decoder
About this tool
Base64 is a way to represent binary data as plain ASCII text, commonly used in data URLs, email attachments, and API payloads. This tool encodes text to Base64 and decodes Base64 back to text, handling UTF-8 correctly so emoji and non-Latin scripts like Chinese or Arabic round-trip without corruption.
