FAQ

Common questions about Base64 Decoder.

What is Base64 encoding?

Base64 is a binary-to-text encoding scheme that represents binary data in an ASCII string format. It is commonly used to transmit data over media that are designed to handle textual data, such as email or HTTP.

Can I decode binary data like images or files?

This tool decodes Base64 text to a UTF-8 string. For binary data, the output may appear as garbled symbols. It works best for text-based Base64 content.

Is my data secure when using this decoder?

Yes. All decoding is done directly in your browser using JavaScript. No input is sent to any server, ensuring complete privacy.

What if my Base64 string has invalid characters?

If the input is not valid Base64, the decoder will likely return garbage or an error. Ensure the string only contains A-Z, a-z, 0-9, +, /, and = for padding.
