Frequently asked questions

What is Base64 used for?

Base64 represents binary data using only safe text characters. It's used in email attachments, data URIs, JSON payloads, basic HTTP auth headers and JWT tokens.

Is Base64 encryption?

No — Base64 is encoding, not encryption. Anyone can decode it. Never use Base64 alone to protect passwords or secrets.
