Decode your Base64 strings back into their original readable text format instantly.
Our Base64 Decoder is designed for developers who need to quickly inspect or recover data from Base64 encoded strings. Whether it's a URL parameter, an authentication token, or an encoded script, our tool handles it with precision.
Handles standard Base64 encoding and ensures that your data is restored exactly as it was before encoding.
All decoding happens locally in your browser. Your sensitive data is never sent to our servers.
What is decoding? Decoding is the process of converting an encoded format (like Base64) back into its original form.
What happens if the input is invalid? If you provide a string that is not valid Base64, the tool will display an error message explaining the issue.
Is there a limit on input size? For the best performance, we recommend decoding strings up to 5MB, though larger strings may work depending on your browser's memory.
