Yes. Your privacy is paramount. All decoding happens directly within your web browser (client-side). Your data is never sent to our servers for processing, ensuring your information remains completely private and secure.

Is this Base64 tool free to use?

Yes, our Base64 Decoder tool is completely free to use. There is no need to download or install any software.

2. Nature of the Service

The Service provides a free, web-based tool for decoding data using the Base64 scheme. All decoding operations are performed locally within your web browser (client-side) using JavaScript.
