Base64 Encoder/Decoder

The following form performs Base64 encoding and decoding of text input. It is 100% local JavaScript, so no data is submitted to the server. You can save this page as HTML and use the encoder/decoder offline by opening the file in a web browser.

There is minimal error checking so decoding of inputs with bad characters or line lengths is likely to fail.
