FAQ

Is Base64 encryption?

No. Base64 is an encoding format, not encryption.

Are JWTs verified here?

The JWT decoder reads header and payload data locally. It does not prove that a token is trusted unless you verify the signature with the correct key in your own environment.

Are images uploaded when converting image Base64?

No. Image Base64 conversion runs in your browser.
