How to use this base64 encoder
Type or paste the text you want encoded. The Base64 output updates immediately. Copy the result when you need it in a header, data URL, or config file.
UTF-8 characters are encoded correctly, not as Latin-1. Decode with the Base64 Decoder if you need the reverse.
Example
The word Toolixo encodes to VG9vbGl4bw== in Base64.

Frequently asked questions
How do I encode text to Base64?
Paste the text. This encoder converts UTF-8 bytes to Base64 using the browser, then shows the ASCII result.
Does it support Unicode?
Yes. Text is encoded as UTF-8 before Base64, so emoji and non-English characters survive a round trip.
Is Base64 encryption?
No. Base64 is encoding, not encryption. Anyone can decode it.
Is my text uploaded?
Processed locally in your browser. We do not upload the text to compute a result.
