This form below allows you to decode Base64-encoded text strings. It’s pretty simple to use - just paste in the Base64 text you want to decode and then press the ‘Decode’ button.

Note: If the text string you are decoding results in a binary output, it will be sent directly back to your client as a stream allowing you to save it as its correct file type. Given the number of possible objects that you could be trying to decode (GIFs, sound files etc.), we’re not going to try and produce a page that will format it all properly! Trying to output a sound file to an HTML stream wouldn’t be that useful anyway...

If you don't want this binary behaviour, pressing ‘Safe Decode As Text’ will try its best to output the decoded stream as text. This may result in gibberish, but it won't result in you being infected by a decoded virus. If you want to be extra, extra careful, you can use the SafeDecode page which doesn't have the binary feature at all, so you can't hit the wrong button.
