Frequently asked questions
Is Base64 secure?
No. It is an encoding, not encryption, and anyone can reverse it. Never use it to hide passwords or secrets.
Why is the output longer than the input?
Base64 turns every three bytes into four characters, so the result is roughly one third larger, plus optional padding with = signs.
