Frequently asked questions

Why is this Base64 tool UTF-8 safe?

The browser btoa() function breaks on non-Latin characters. This tool encodes via TextEncoder first, so Chinese, emoji and accented characters round-trip correctly.

Is Base64 encryption?

No. Base64 is an encoding, not encryption — anyone can decode it. Never use it to protect secrets.
