Frequently Asked Questions

What is Base64 encoding used for?▾

Base64 encoding converts binary data into ASCII text, making it safe to transmit through text-based systems like email, URLs, and JSON APIs. Common uses include encoding images for data URIs, handling authentication tokens, and embedding binary data in XML or HTML.

Is Base64 encoding the same as encryption?▾

No. Base64 is an encoding scheme, not encryption. It converts data to a different format but does not protect or secure it. Anyone can decode Base64 strings — it should not be used for sensitive data protection.
