How to hide personal data on a bank statement before sharing it

You're asked for a bank statement to prove your address, show you have an account in your name or set up a payment. What they really need is your name, your address and sometimes your account number. But the document also shows your transactions, your balance and what you spend your money on. You don't have to share that information.

What to hide (and what not to)

First figure out what data the person asking for the document really needs. As a general rule:

• You can usually hide: the list of transactions, the balance, debits and credits, the full card number and any investment or loan details.
• You usually need to leave visible: your name, address, the bank's name, the statement period or date and, if they need it to pay you, your account number (CLABE in Mexico).

The most common mistake: covering it with a black box

Many people open the PDF in an editor, draw a black box over the data and save it. On screen it looks hidden, but the text is still inside the file: anyone can select and copy it, or find it with the PDF reader's search. There have been cases of public documents from companies and governments that leaked information for exactly this reason.

Redacting properly means removing the content from the marked area, not just covering it.

How to redact a bank statement step by step

1. Remove the pages you don't need first. If you're only asked for your address, the first page is probably enough. Use Extract pages to keep just that page; that way there's less to redact.
2. Open Redact PDF and load the document.
3. Zoom in and mark each area you want to hide. Leave a little margin around the data.
4. Check every page: data like the account number is often repeated in the header or footer of each page.
5. Apply the redaction and download the copy.

Check that the redaction worked

Before sending the file, do this one-minute check on the downloaded copy:

1. Search for it: open the PDF, press Ctrl + F (or the magnifying glass on your phone) and type part of the data you hid, for example the last digits of your account. It shouldn't be found.
2. Try to copy it: select the redacted area, copy and paste into a notepad. The original text shouldn't appear.
3. Check the edges with zoom: make sure the tops or bottoms of the letters aren't peeking out.

Other documents where the same applies

• Payslips: to prove where you work, you don't always need to show your salary or deductions.
• Copies of IDs: in some cases you can hide the signature or ID number if the recipient doesn't need them.
• Contracts and invoices that you're going to show someone as an example or reference.

If you're also sending the document by email, consider adding a password to the redacted copy.
