Common questions.
What is Base64?
Base64 represents binary data using a limited set of printable ASCII characters. It is an encoding format, not encryption.
Can Base64 hide or secure sensitive information?
No. Anyone can decode Base64. Use encryption when information must remain confidential.
Does this tool support emoji and Unicode?
Yes. Text is encoded and decoded as UTF-8, so emoji, accents, and multilingual characters are preserved.
Is my text uploaded?
No. Encoding and decoding run entirely inside your browser.
