Base64 Encoder/Decoder Guide: Learn to Encode and Decode Text

Base64 shows up everywhere once you start looking: API payloads, email attachments, configuration files, and those long “data:” strings in HTML. It can feel mysterious because the output looks like random characters, but the idea is simple: turn bytes into safe-to-transport text, and back again.
