Base64 is an encoding scheme that converts binary data into a text-safe format made up of letters, digits, and a few special characters. It's commonly used to embed files or images in emails, or to carry binary data as text in API requests.

Is Base64 encoding a form of encryption?

No. Base64 is not encryption — anyone can decode it back to the original data. It only converts data into a text-compatible format and should never be used to protect sensitive information.

Why am I getting an error when decoding?

The tool shows an error if the text you entered isn't valid Base64 — for example, it contains disallowed characters, its length isn't a multiple of 4, or it doesn't decode into valid text.

Are non-English characters and emoji handled correctly?

Yes. Encoding first converts the text to UTF-8 bytes before processing, so accented characters, emoji, and other Unicode characters are encoded and decoded without any data loss.

Is my data sent to a server?

No. All encoding and decoding happens entirely in your browser using JavaScript; the data you enter is never sent to any server.
