FAQs
Does Base64 protect a secret by encrypting it?
Base64 is an encoding, not encryption. Anyone who has a valid encoded value can decode it without a secret key, so do not treat it as confidentiality protection.
Which inputs do I need for UTF-8 Safe Base64 Encoder & Decoder?
Use Input Text or Base64 String; Operation. The built-in examples show how those fields fit together.
What should I check before using this result?
For binary image files, use Image to Base64 (T187). Check the assumptions and output against your intended task before relying on the result.
