About the Base64 Encoder / Decoder tool
Convert between plain text and Base64 instantly, with correct UTF-8 handling for emoji and non-Latin alphabets. URL-safe output is one toggle away.
Base64 is an encoding, not encryption — anyone can decode it. Never use it to hide secrets; use it for transport and storage of binary-in-text data.
