Frequently asked questions
What is Base64 used for?
It represents binary or special-character data using only safe ASCII characters — common in APIs, email attachments and data URLs.
Is Base64 encryption?
No. Base64 is encoding, not encryption — anyone can decode it. Never use it to protect secrets.
