What is base64 encoding used for?

Base64 turns binary or text data into a safe ASCII string, which is how data is shipped inside URLs, JSON API payloads, emails, and data URLs.

Does it support Hindi and other languages?

Yes, the encoder and decoder use UTF-8, so multilingual text and emoji are handled correctly in both directions.

Why does encoded text look longer?

Base64 uses 4 characters to represent every 3 bytes of data, so the encoded output grows by roughly 33% in length. That overhead is normal.

Is my data uploaded anywhere?

No, all encoding and decoding happens locally in your browser. Your text never leaves your device.
