What is Base64 Encoding Used For?

Base64 encodes binary data into 64 printable ASCII characters, enabling binary transmission over text-only protocols like email (MIME) and inline data URIs.

Frequently Asked Questions:

No. Base64 is an encoding format, not encryption. Anyone can decode Base64 data back to its original form.
