Base64 decoding converts Base64-encoded text back into its original form. Our free Base64 Decoder instantly reverses Base64 encoding, revealing the original text content right in your browser.
Base64 is used extensively in web development for data URIs, email attachments, API tokens, and more. When you encounter Base64-encoded data, this tool helps you quickly decode it to see the original content.
The decoder handles standard Base64 with proper UTF-8 support, meaning non-ASCII characters like accented letters, CJK characters, and emoji are decoded correctly. Everything runs locally — no data is sent to any server.
