Frequently Asked Questions

What is Base64 used for?

Base64 encodes binary or arbitrary data into a text-safe format, commonly used for embedding images in CSS/HTML, encoding email attachments, or passing data in URLs and JSON.

Is Base64 encryption?

No. Base64 is an encoding scheme, not encryption — it provides no security or confidentiality, since it can be decoded by anyone.
