Frequently Asked Questions

What is Base64?

Base64 is an encoding scheme that converts binary data into a sequence of printable ASCII characters. It's commonly used to transmit data over media that are designed to handle only text, such as in email attachments or for embedding binary data like images and fonts directly into HTML or CSS files.

Is it safe to use this website with sensitive data?

Yes. The most important feature of gobase64.com is that all processing is done entirely within your web browser (client-side). Your data is never sent to our servers or any third party. It's as secure as running a program on your own computer.

Why do some tools not work offline?

The core functionality of all tools works offline. However, the website itself and some third-party libraries (like Google Fonts, SweetAlert2) are loaded from the internet. If you load the website while online, you can then go offline and continue to use the tools.

How do I use the "Base64 to Image" tool?

Simply paste your full Base64 string, including the data URI scheme (e.g., data:image/png;base64,...), into the input box and click "Process". The image will appear in the preview area below.

What does "URL-Safe" Base64 mean?

Standard Base64 includes the characters '+' and '/', which have special meanings in URLs. The URL-safe variant replaces '+' with '-' (minus) and '/' with '_' (underscore), so the encoded string can be safely used in URL paths and query parameters without being accidentally misinterpreted.

Can I use this for commercial purposes?

Yes, absolutely. The tools are free to use for any purpose, personal or commercial. Please refer to our Terms of Service for more details.
