Base64 Encoder & Decoder

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It's commonly used to encode data for transmission over text-based protocols.

Base64 encoding is often used for embedding images in HTML/CSS, encoding email attachments, storing complex data in JSON, and transmitting binary data over APIs.

Encode — Enter any text in the input field and get the Base64 encoded version instantly. Supports full UTF-8 characters including emojis.

Decode — Paste a Base64 string to convert it back to the original text. Invalid Base64 strings will show an error message.
