Decode from Base64 or Encode to Base64 - instantly

ENCODE (From string to Base64) DECODE (From Base64 to string)

Then this page is made for you: use the super simple online form above to decode or encode your data.
If you're interested about the inner workings of the Base64 format, just read below.

We take the confidentiality of your data very seriously. That's why this base64 encoder and decoder function works on Client's side and NOT with a server-side script.
None of your data (ascii or base64 string) goes to our server.
You can input whatever you want, it won't be recorded. It's only between you and your browser.
Have a doubt? Check the page source by yourself ;)

More than easy, just enter enter a string in the input box, let's try with the following text:

OnlineHashCrack is an online service that attempts to recover your passwords thanks to
the power of GPUs,including hashes like MD5, NTLM, Wordpress, WPA dumps (handshakes),
Office encrypted files (Word, Excel or Powerpoint)obtained in a legal way

The above text is then encoded in base64, represented as a byte sequence of 8-bit-padded ASCII characters encoded in MIME's Base64 scheme as follows:

This result is called base64 encoded string, and can be used for several purpose: be passed through URLs or HTTP protocols, hide data, etc.
This example use a simple text, but lot's of other format like image or binary data can be base64 encoded as well.

Base64 is a group of similar binary-to-text encoding schemes that represent binary data in an ASCII string format by translating it into a radix-64 representation. The term Base64 originates from a specific MIME content transfer encoding.
Each base64 digit represents exactly 6 bits of data.
