How to use this tool

Base64 is an encoding, not encryption. It does not hide secrets. This tool supports UTF-8 text, including emoji, and standard Base64 or URL-safe Base64. Binary files are outside this text tool’s scope.

Choose Try sample, then Encode. To reverse the operation, paste the result into Input text and choose Decode. Input and results are never uploaded or saved by this tool.
