Frequently Asked Questions

Does the JWT Debugger store my history or inputs?
No. We have a strict zero-retention policy. The JWT Debugger processes your input statelessly, meaning once you close the browser tab, your data is completely wiped.
What happens if I input a massive file into the JWT Debugger?
GoBase64 is optimized to handle large inputs using the HTML5 FileReader API. The JWT Debugger will chunk and process the data locally, so it won't crash our servers, though extremely large files may be limited by your browser's RAM.

Absolutely. Because GoBase64 is a 100% client-side application, your data never leaves your device. The JWT Debugger processes everything locally in your RAM.
