Base64 Encode / Decode
Convert text to Base64 or decode it back, live as you type. Full UTF-8 support, so accented letters, emoji, and non-Latin scripts round-trip correctly.
What Base64 is for
Binary-safe text, not encryption.
Base64 turns arbitrary bytes into a string using only letters, digits, +,
and /, safe to embed in JSON, URLs, or email where raw binary would
break. It's not encryption: anyone can decode it back instantly, so it doesn't hide
or protect anything on its own.
URL-safe variant
Standard Base64's + and / characters have special meaning
in URLs. The URL-safe variant swaps them for - and _ and
drops the trailing = padding, so the result can go straight into a
query string or file name.
