How to use Base64 encoder
Convert ordinary Unicode text into a Base64 string for a data exchange or development task. The input is encoded as UTF-8 bytes before Base64 conversion. Use the image-specific tool for image data URLs. Base64 is reversible encoding, so it should not be used to protect confidential information.
