Your CUIL or CUIT ties together your identity, work and tax records in Argentina, so you often want it hidden on a document shared for another reason. This tool blacks it out and removes it on export, all in your browser (en tu navegador), so the document is never uploaded.

How to black out a CUIL or CUIT on a PDF

  1. 1

    Add your PDF

    Drop in the document that shows your CUIL or CUIT.

  2. 2

    Cover the number

    Draw a black box over it.

  3. 3

    Apply and download

    On export the number under the box is permanently removed.

Why black out your CUIL or CUIT locally

A visible CUIL or CUIT links a document straight to your records. Redacting it in the browser means the version with your number is never uploaded to a server.

Frequently asked questions
