Base64 Encoder / Decoder
Encode text to Base64 or decode it back, instantly and in your browser. UTF-8 safe, so emoji and non-English text survive.
Frequently asked
What is Base64 used for?
It represents binary or text data as a plain ASCII string — handy for embedding data in HTML/CSS/JSON, data URLs, or simple config where special characters would break things.
Does it support emoji and non-English text?
Yes. Encoding and decoding are UTF-8 aware, so Unicode survives the round trip.
