Frequently Asked Questions

What is Base64 encoding used for?

It is commonly used to encode binary data or special characters into a standard text format for easy embedding in HTML/CSS, URLs, or transmission via email.

No, Base64 is an encoding scheme, not encryption. It does not hide data securely; it simply formats it differently. Do not use Base64 to secure sensitive passwords.
