Base64 Encoder / Decoder
Encode text to Base64, or decode a Base64 string back to text.
What Base64 is for
Base64 turns arbitrary bytes into plain ASCII text using 64 printable characters — commonly used to embed binary data (like images) in text formats such as JSON, HTML, or email, where raw bytes aren't safe to include directly. It's an encoding, not encryption — anyone can decode it back instantly.
