Frequently asked questions
Does it support emoji and non-English text?+
Yes, Unicode text is encoded and decoded correctly.
Is Base64 the same as encryption?+
No, Base64 is just an encoding scheme, not encryption — anyone can decode it.
Base64 shows up constantly in web development: embedding small images directly in CSS, encoding Basic Auth credentials, storing binary data in JSON, or reading a JWT payload. This tool handles both directions instantly as you type, and correctly handles Unicode characters (accents, emoji, non-Latin scripts) that naive Base64 implementations often mangle. Switch between encode and decode with one click, or use the swap button to feed your output straight back in as new input.
