Base64 is reversible encoding, not encryption. Do not use it to hide secrets.

Worth knowing

Base64 is encoding, not protection.

Anyone with the Base64 text can decode it. Use it when a system expects Base64, not as a way to hide passwords, secrets or private information.

Before you use it

Copy only the finished side.

For an API, config file or form field, the output box is the value you want to paste onward. The original input stays untouched so you can compare before copying.

The annoying bit

It looks encrypted. It absolutely is not.

Sometimes a system wants perfectly ordinary text wrapped in Base64 first. The annoying part is just getting from one representation to the other without mangling Unicode characters.
