What would you like to do next?
Decode Base64 to text
Paste a Base64 string above to decode it back into readable text instantly. This reverses Base64 encoding, so you can read data that was packed for a URL, a JSON field, a data URI or an email header. Unicode is handled correctly, and the decoding happens entirely in your browser.
If decoding fails
An error usually means the input is not valid Base64. Check for missing characters or extra spaces, then try again.
