How do you convert Base64 to a string?
A Base64 to string converter decodes a Base64 value back into the original string. Snabbit removes any whitespace, decodes the Base64 to bytes, and reads those bytes as UTF-8 to rebuild the string exactly. It runs entirely in your browser, so the encoded data you paste stays private and is never uploaded.
How to use the Base64 to String
- 1 Paste your Base64 value into the input box.
- 2 The decoded string appears instantly.
- 3 Bytes are decoded as UTF-8 to rebuild the string.
- 4 Copy the recovered string.
What you can use it for
- Recovering a string stored as Base64 in a database.
- Decoding a Base64 field from a JWT payload.
- Reading Base64 values out of logs or config files.
- Verifying a string-to-Base64 round trip.
Frequently asked questions
Will it handle Base64 produced by other languages?
Yes, as long as it is standard Base64. Values produced by Python, PHP, Java or JavaScript all decode here, including ones split across multiple lines.
What if there is missing padding?
Many strings without trailing = padding still decode. If the input is genuinely malformed, the output is left empty so you know the value was not valid Base64.
Is decoding private?
Yes. It runs locally in your browser with the native atob function; nothing is sent to a server.
