What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that represents binary data as ASCII characters. It is commonly used to embed data in URLs, emails, and JSON.

Does this tool support Unicode?

Yes. The encoder uses TextEncoder/TextDecoder to properly handle Unicode characters including emojis, accented letters, and non-Latin scripts.

Is Base64 encryption?

No. Base64 is an encoding, not encryption. Anyone can decode a Base64 string. Do not use it for security purposes.

Is my data sent to a server?

No. All encoding and decoding happens entirely in your browser. Your data never leaves your device.

Can I decode any Base64 string?

Yes, as long as the string is valid Base64. If the input is not valid Base64, the tool will display an error message.
