Base64 is an encoding format, not encryption. It is used to represent binary or plain text data in ASCII-safe form so it can travel through systems that expect text.
Check the payload directly
Developers see it constantly in HTTP auth headers, data URLs, email payloads, file uploads, and embedded assets. Because it looks opaque at a glance, a fast decoder saves time during debugging.
