How Base64 encoding works
Base64 converts binary or text data into ASCII characters, which makes transport safer across systems that expect plain text.
- Enter plain text to encode, or paste Base64 text to decode.
- Choose Encode or Decode depending on your workflow.
- Review the output and copy it for API payloads, URLs, or headers.
Base64 is encoding, not encryption. Anyone can decode it back, so do not treat Base64 as a security layer.
