How to Decode Base64 Safely
Base64 is encoding, not encryption. Here is how to inspect UTF-8 text without over-trusting it.
Know what Base64 is
Base64 turns bytes into text that can be copied through systems that expect plain characters. It does not hide the original content, so treat decoded values as plain text.
Be careful with secrets
A local tool avoids uploading the string, but your browser session and device still matter. Avoid pasting production secrets unless you have to.
