Is Base64 encryption?

No. Base64 is an encoding, not encryption — anyone can decode it instantly. Never use it to hide sensitive data.

Why is the output longer than the input?

Base64 represents every 3 bytes as 4 characters, so the encoded text is about 33% larger than the original.

Does it handle emoji and non-English text?

Yes — the input is treated as UTF-8 before encoding, so all characters round-trip correctly.

About the Base64 Encode tool

Base64 encoding represents arbitrary text or binary data using only 64 printable ASCII characters (A–Z, a–z, 0–9, + and /), with = for padding. It is how binary data travels safely through text-only systems — email attachments, data URLs, JWT tokens, and HTTP Basic Auth headers. This encoder is UTF-8 safe, so emoji and non-Latin scripts round-trip correctly.
