Frequently Asked Questions

What is Base64?

Base64 is a format that converts binary data or text into a safe character sequence (A-Z, a-z, 0-9, + and /), useful for embedding data inside JSON, XML, URLs, or text documents.

Is Base64 a form of encryption?

No. Base64 is encoding only, not encryption — anyone can easily decode a Base64 string. Don’t use it to hide sensitive information.

Does this tool support non-English characters?

Yes. Encoding handles UTF-8 text, so accented letters, emoji, and other special characters encode and decode correctly.
