Encode plain text, JSON, or raw code into UTF-8 Base64 strings or decode Base64 data 100% client-side.

Understanding UTF-8 Base64 Encoding

What is Base64?

Base64 represents binary data in an ASCII string format by translating it into a radix-64 representation, commonly used in HTTP headers, data URIs, and email attachments.

UTF-8 Unicode Support

Standard JavaScript btoa fails on Unicode characters. Our tool uses full UTF-8 byte stream encoding to support non-ASCII symbols and Bengali characters safely.

📖 Detailed Guide & Use Cases

Encode text strings, JSON data, and code snippets into Base64 ASCII representations or decode Base64 data strings back into UTF-8 text.
