Base64 encoding turns binary data into ASCII text, which is useful for embedding images in HTML, sending attachments in APIs, or storing binary in JSON.

Encoding is straightforward: you input text or upload a file and get a Base64 string. Decoding reverses the process so you can recover the original content or download the file.
