Base64 Decode
Paste Base64 and get the original text back. UTF-8 aware decoding handles international text and emoji that other decoders mangle.
Frequently asked questions
My Base64 has line breaks and spaces — will it still work?
Yes. This decoder strips all whitespace before decoding, so Base64 copied from certificates, PEM files or wrapped emails works fine.
Why did decoding fail with an error?
The input wasn't valid Base64. Common causes: missing padding at the end, typos, or the string contains characters outside the Base64 alphabet. The exact problem is shown in the error message.
Can I decode Base64 images here?
You can decode the bytes, but this tool renders output as UTF-8 text, so binary content will look like gibberish. For text payloads — tokens, encoded strings, Basic Auth credentials — it works perfectly.
