How do I encode text to Base64?

Type or paste your text into the encoder and the Base64 output appears automatically. Copy it with one click.

Does it handle Unicode and emoji?

Yes. The encoder is UTF-8 aware, so multibyte characters including emoji encode and decode correctly.

Is Base64 encryption?

No. Base64 is an encoding, not encryption — it is fully reversible by anyone. Do not use it to protect secrets.

No. Encoding runs locally in your browser, so your text never leaves your device.
