What is Base64 Decoding?

Base64 decoding is the process of converting a Base64-encoded text string back into the original binary data or plain text. If you received Base64-encoded data through web development, API communication, or email processing, this tool lets you quickly verify the original data. All conversions happen directly in your browser—no data is sent to a server—so even sensitive information can be decoded safely.

FAQ

What is the difference between Base64 decoding and encoding?

Encoding converts original data into a Base64 string, while decoding reverses the process, restoring the Base64 string back to the original data. Neither is encryption; both are simple data format conversions.

Which character encoding should I select?

In most cases, UTF-8 is the right choice. UTF-8 supports virtually all characters worldwide and is the most commonly used character encoding on the web.
