Frequently Asked Questions

What is Base64?

Base64 is an encoding scheme that converts binary data to ASCII text. It's used in email attachments, data URLs, API authentication headers and JSON web tokens.

Is Base64 encryption?

No. Base64 is encoding, not encryption. It's easily reversible and provides no security. Never use Base64 to hide sensitive data.
