Frequently asked questions
What is Base64 encoding actually used for?
Base64 converts binary or text data into a safe set of ASCII characters, commonly used for embedding images in CSS/HTML, encoding data in URLs, email attachments (MIME), and JWT tokens.
Is Base64 the same as encryption?
No — Base64 is encoding, not encryption. It provides zero security or confidentiality; anyone can decode it instantly. Never use Base64 alone to protect sensitive data.
Does this tool support non-English characters?
Yes. Text is encoded as UTF-8 bytes before Base64 conversion, so accented characters, emoji, and non-Latin scripts round-trip correctly.
