FAQ

Can I decode Base64 images directly in browser?

Yes. Paste a data URL or raw Base64 image string and the tool renders an image preview with detected MIME type and size.

Does URL decoding handle plus signs correctly?

Yes. In decode mode, plus signs are interpreted as spaces before URI decoding, matching common form encoding behavior.

Can I decode only JWT header or payload?

Yes. The JWT mode lets you choose and decode header, payload, or signature-related segments independently.
