What Is Base64 For?
Base64 turns binary or text data into a safe set of characters that survive systems built for plain text, such as email, data URIs, and JSON. It is encoding, not encryption, so it is for safe transport, not for hiding secrets.
Frequently Asked Questions
Does it support emojis and accents?
Yes. The tool is UTF-8 safe, so emojis and accented characters encode and decode correctly.
Is Base64 secure?
No. Base64 is reversible encoding, not encryption. Anyone can decode it, so never use it to protect passwords.
Is my input uploaded?
No. Everything is processed locally in your browser.
