Use our fast online tool below to encode strings to base64 or to decode base64 back to it’s original string.

Note:   if decoding base64 when investigating malware injected scripts, sometimes the decoding will be another base64 string as the author may have double encrypted their malicious code – simple copy the 2nd base64 string into the decode box and decode again.

We hope you find our free online base64 encode / decode tool useful!
