111 Base64 encoder - encode data to a Base64 string online
Text data to encode. Please paste a text bellow and click Encode. If you want to encode a file, please go to Base64 file encoder or Image-to-Base64 encoder.

How the Base64 encoder works

  1. 1. A browser takes the text data and converts them to a binary stream
  2. 2. The binary data stream is POSTed to a server by browser
  3. 3. Server takes the binary stream and encodes the data to a Base64 text data
  4. 4. The original decoded data are sent to the client as a text stream if you choose 'Decode to a text file' or as text to textbox

Limit for this Base64 encoder is 10MB. Please do not post more data than the limit

Privacy notes for the Base64 encoder

This page works "on the fly". We do not store nor monitor data posted to this page. The data are only encoded to a base64 text in a server memory and sent to a client.
