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.
