Base64 Encoder / Decoder
Encode text to Base64 and decode it back — Unicode-safe, so emoji, Hindi, and CJK text round-trips without corruption.

How it works
How Base64 encoding works
Text → UTF-8 bytes → Base64
Your text is first converted to UTF-8 bytes, then re-encoded into the 64-character Base64 alphabet. That two-step path is what keeps emoji and non-Latin scripts intact.
Decoding is strict
The decoder accepts the standard alphabet plus optional padding, and fails gracefully (with a clear message) on garbage instead of emitting corrupted text.
Swap directions
Use the "Use result as input" button to chain operations — encode, then feed the output straight back into the decoder to verify a round trip.
Questions
Base64 FAQ
Why use Base64 for text?
Base64 turns binary or tricky text into a safe subset of ASCII (A–Z, a–z, 0–9, +, /, =) that survives email, JSON fields, URLs, and other text-only channels without corruption.
Does it support emoji and other languages?
Yes — text is encoded from UTF-8 bytes, so emoji, Hindi, Arabic, CJK, and any other Unicode content round-trips correctly. Plain atob-based tools corrupt those; this one does not.
Is Base64 encryption?
No. Base64 is encoding, not encryption — anyone can decode it instantly. Never use it to protect secrets.
What is the = padding at the end?
Base64 processes data in 3-byte groups. When the input is not a multiple of 3 bytes, the output is padded with = characters so decoders know how much to discard. Some tools strip it; this tool accepts both.
