What is Base64 Encoder/Decoder?
Base64 is a binary-to-text encoding scheme that converts binary data into an ASCII string format. It's commonly used to encode binary data for transmission over text-based protocols like email (MIME) and for embedding images or files directly in HTML, CSS, or JSON.
Why Use This Tool
Base64 encoding is essential when you need to safely transmit binary data through text-only channels, embed images in HTML/CSS, store binary data in JSON, or encode authentication credentials in HTTP headers.
