Frequently asked questions
What is Base64 used for?
It represents binary data using plain text characters, so files can travel safely through systems built for text, such as email or JSON payloads.
Is Base64 encryption?
No. It is an encoding, not encryption — anyone can decode it. Never use it to protect secrets.
