Frequently Asked Questions

What is Base64 used for?

Base64 encodes binary data as ASCII characters so it can travel safely through text-only channels: data URIs in CSS/HTML, JSON payloads, basic-auth headers, and email attachments (MIME).

Is Base64 encryption?

No. Base64 is reversible encoding, not encryption. Anyone who sees the encoded string can decode it instantly. Never use Base64 to hide secrets.
