Base64 encoding and decoding calculator

This calculator can be used to encode text or files to Base64 format and decode Base64 strings back to their original format. Base64 is commonly used to encode binary data in text format for transmission over media that are designed to deal with text.

Calculation Formula

Base64 encoding converts binary data to an ASCII string format by translating it into a radix-64 representation.

Where:
Encoding: Converts binary data to Base64 format
Decoding: Converts Base64 format back to original binary data

How to Use This Calculator

  1. Select the operation you want to perform: "Encode to Base64" or "Decode from Base64".
  2. If encoding, enter the text you want to convert to Base64 in the input field.
  3. If decoding, enter the Base64 string you want to convert back to its original format.
  4. Click the "Calculate" button to perform the operation.
  5. The result will be displayed in the result field.

Base64 Encoding

Base64 encoding converts binary data to an ASCII string format by translating it into a radix-64 representation. This is useful when you need to transmit binary data over media that are designed to deal with text, such as email systems or web forms.

Base64 Decoding

Base64 decoding reverses the encoding process, converting the ASCII string back to its original binary data. This is necessary when you need to retrieve the original binary data from a Base64 encoded string.

Example Use Cases

  • Embedding images in web pages
  • Converting binary data to be transmitted in email
  • Storing binary data in text fields in databases
  • Encoding configuration files that contain binary data
