Frequently Asked Questions
Is it secure?
Yes, tokens are decoded locally in your browser.
Does the JWT Decoder send my code or data to any server?
No. Everything runs locally in your browser. Your code, data, and files remain on your device at all times.
What input size limits apply?
The tool handles most practical input sizes. Very large files may cause browser performance limitations since processing is done client-side.
Can I use this in my development workflow?
Absolutely. The tool is designed for developers and integrates well into local development workflows without needing command-line utilities.
