Black out your DNI or NIE number before sharing
Hide your Spanish ID number before you share, without uploading it.
Your DNI or NIE number identifies you across Spanish administration and banking, so you often want it hidden on a document shared for another purpose. This tool blacks it out and removes it on export, all in your browser (en tu navegador), so the document is never uploaded.

Why black out your DNI or NIE locally
A visible DNI or NIE on a shared document is a lasting exposure. Redacting it in the browser means the version with your number is never uploaded to a server.
Frequently asked questions
