Frequently Asked Questions
What is Base64 used for?
Base64 encodes binary data as printable ASCII text, commonly used to embed images in CSS/HTML, encode data in URLs, or transmit binary data over text-only protocols like email (MIME).
Is Base64 encryption?
No — Base64 is an encoding, not encryption. It provides zero confidentiality; anyone can decode it instantly. Never use it to protect sensitive data.
Does this support Unicode text?
Yes — this tool correctly handles Unicode (emoji, accented characters, non-Latin scripts) by UTF-8 encoding the text before Base64 conversion.
