How to Use
- Select Encode to convert text to Base64, or Decode to convert Base64 back to text.
- Enter your text or Base64 string in the input area.
- Click Encode or Decode to process your input.
- Copy the result using the Copy to Clipboard button.

About Base64 Encoding
Base64 is a way to encode binary data into ASCII text format. It's commonly used when you need to transmit binary data over text-based systems.
Common Uses:
- Encoding binary data in email attachments (MIME)
- Embedding image data directly in HTML or CSS
- Storing complex data in JSON format
- Transmitting data in URLs
- Storing binary data in databases that don't support binary formats
Base64 uses a set of 64 characters (A-Z, a-z, 0-9, + and /) to represent binary data, with = used for padding.
How the Calculator Works
This tool uses the built-in browser functions btoa() and atob() to encode and decode Base64. When encoding, your input text is converted into a Base64 string. When decoding, the tool converts a Base64 string back to its original text form. If the input is invalid for the selected operation, an error message will be shown.
- Encoding only works with UTF-8 text. Special characters may cause errors.
- Decoding requires a valid Base64 string. Invalid input will result in an error.
Frequently Asked Questions (FAQ)
Base64 encoding is a way to represent binary data as ASCII text using 64 different characters. It's commonly used for data transfer in email, URLs, and web APIs.
Encoding only works with standard UTF-8 text. If your input contains unsupported characters (like emojis or certain symbols), you may see an error.
Decoding requires a valid Base64 string. If your input is not properly formatted, the tool will show an error.
All encoding and decoding is done locally in your browser. No data is sent to any server.
