FAQ

Is anything uploaded? No. Tools run locally in your browser. Validate, repair and convert without uploading files.

Fast workflow: validate -> fix the first real error -> validate again -> export/convert.

Local verification snippet

Run a quick local check before export/convert:

const normalized = token.trim().replace(/-/g, '+').replace(/_/g, '/');
const padded = normalized + '='.repeat((4 - (normalized.length % 4)) % 4);
const raw = atob(padded);
console.log(raw.slice(0, 120));
