Encode UTF-8 Text to Base64 for Free

Paste ordinary text and use the encode action to generate its Base64 representation. Inspect the output before copying it into the destination, and remember that this representation is readable after decoding rather than a way to encrypt the content.

Decode Base64 Text Online for Free

Enter a Base64 text value and use the decode action to recover its UTF-8 content. Check the resulting characters for the expected message, since incomplete input or encoded binary data may not produce the readable text you intended.

Use a Base64 Encoder and Decoder for Free

Switch between the forward and reverse actions to compare plain text with its encoded representation, then copy or download the result. Avoid unnecessary secrets because text drafts may persist in browser storage after your current session.
