Base64 Encoder & Decoder

What is a Base64 Encoder & Decoder?

Base64 is an encoding scheme that converts binary data or text into a string of ASCII characters using 64 printable characters. It is widely used to transmit binary data over systems that handle text, such as email (MIME), embedding images in HTML/CSS as data URIs, storing binary blobs in JSON, and encoding credentials in HTTP Basic Authentication headers. Base64 does not encrypt data — it only encodes it. Anyone who has the Base64 string can decode it instantly.
