How the Base64 decoder works

  1. 1. A browser takes the text Base64 file and sends them to server as a binary Base64 stream
  2. 2. Server takes the binary file and decodes the Base64 data to an original binary stream
  3. 3. The original decoded data are sent to the client as a binary stream if you choose 'Decode to a binary file' or as text strem encoded by selected charset if you choose 'Decode to a textbox'
Limit of this Base64 decoder is 10MB. Please do not post bigger Base64 file than the limit.
