Base64 Decode

The Base64 Decode online is a free decoder for online Base64 to text or binary conversion. It is a tool that transforms Base64 data to its native format. This online decoder is both sophisticated and simple. Its superpower is the ability to detect the encoding standard automatically. This converter allows you to "decrypt" some Base64 strings when other online or offline decoders are impotent to do so since they only support the "main" standard.


How To Use Base64 Decode?

  1. Copy and paste your string into the "Base64" field.
  2. Choose an algorithm standard (if you do not know, leave it as it is, as the decoder will automatically detect it).
  3. Enable the tight decoding mode to ensure that your Base64 string only contains valid characters.
  4. Select the "Character Encoding" list if you know what encoding the original data was in.
  5. Select the "Decode Base64" option.
  6. The result of the "Text" field can be downloaded or copied.
