Meet Base64 Decode and Encode, a simple online tool that does exactly what it says; decodes Base64 encoding and encodes into it quickly and easily. Base64 encode your data in a hassle-free way, or decode it into human-readable format.

Base64 encoding schemes are commonly used when there is a need to encode binary data that needs be stored and transferred over media that are designed to deal with textual data. This is to ensure that the data remains intact without modification during transport. Base64 is used commonly in a number of applications including email via MIME, and storing complex data in XML or JSON.

Advanced options

  • Character set: Our website uses UTF-8 character set, your input data is transmitted in that format. Change this option if you want to convert it into another one before encoding. Note that in case of textual data the encoding scheme does not contain their character set, so you may have to specify the selected one during the decoding process. As for files a binary option is the default, which will omit any conversion; this is required for everything except plain text documents.
  • Newline separator: Unix and Windows systems uses different line break characters, prior encoding either variants will be replaced within your data to the selected option. At the files section this is partially irrelevant since they contain intended versions, but you can define which one to use for the encode each line separately and split lines into chunks functions.
  • Encode each line separately: Even newline characters are converted to their base64 encoded forms. Use this option if you want to encode multiple independent data entries separated with line breaks. (*)
