About the Base64 Encoder & Decoder

Convert text to Base64 and back. Useful for reading an encoded token, building a data URI, or inspecting a value copied out of a config file or HTTP header.

• Encode and decode with full UTF-8 support
• Decodes padded and unpadded input
• Everything runs locally — safe for tokens and credentials

Frequently asked questions

Is Base64 encryption?

No. Base64 is an encoding, not encryption — anyone can decode it. It exists to move binary data safely through text-only channels.

Is it safe to decode a token here?

Yes. Decoding happens in your browser and nothing is transmitted or stored.
