Landlords, lenders, visa offices and employers often ask for a bank statement. Handing over a full statement exposes more than they need: every transaction, your full account number and sometimes your address. Redacting it is normal and sensible. Doing it wrongly is a trap, because a black box drawn over text in a PDF does not remove the text.
Step 1: ask what is required
Before you remove anything, ask the recipient what they need to see. Requirements vary by country and by organisation, and over-redacting can get your application rejected. A short message such as "Which details do you need on the statement?" avoids both over-sharing and a second request.
Step 2: decide what to keep and what to remove
The common pattern across published guidance for rental applications is the same:
| Usually keep visible | Usually redact |
|---|---|
| Your name (so it matches the application) | Full account number (keep the last four if you want to show it is yours) |
| Bank name and logo | Routing or sort code, and any other account identifiers |
| Statement period dates | Individual transactions, payees and merchants you do not need to show |
| Income deposits | Balances of linked accounts, card numbers, check images |
| Opening and closing balance, if requested | Your address, if the recipient does not need it |
Treat this as a starting point, not a rule. If a recipient asks for transactions to be visible, give them what is asked; if you are unsure, redact less and ask.
Do not change amounts, dates or names. Redaction means hiding what is not needed. Editing figures on a financial document is a different thing altogether, and recipients who verify statements will spot it.
Step 3: why a black box is not enough
Many PDF editors let you draw a black rectangle, or highlight text in black. That paints a shape over the text. The characters are still in the file, so anyone can select, copy or search them, or delete the rectangle. Account numbers often appear in the header and footer of every page, which makes the mistake easy to make and expensive. Our guide on why black-box redaction fails shows exactly how the text leaks.
Step 4: redact it for real
- Download the statement as a PDF from your bank's website or app. Use the official PDF rather than a screenshot.
- Open the PDF redaction tool and drop the file in. It opens on your device; nothing is uploaded, which matters for a financial document.
- Draw a box over each item to remove. Use Mark matches to search for the account number and mark every place it appears on every page. It marks the whole text run it is part of, so check the boxes.
- Go through every page, including headers, footers and the small print where account numbers or addresses repeat.
- Choose the resolution (200 dpi is a good balance for reading; 300 dpi is sharper but larger), then export.
The tool renders each page to an image, paints black over the marked areas, and rebuilds the PDF from those images. There is no text layer underneath, because there is no text layer at all. The trade-off is that the result is no longer searchable and the file may be larger. For a statement that someone is going to read, that is usually fine.
Step 5: check the result
- Open the redacted file and press
Ctrl/⌘ + F. Search for the account number. You should find nothing. - Try to select text across a black box and paste it somewhere. Nothing should come out.
- Look at the file properties. The tool also removes document metadata such as author and creating software.
- Zoom in on every page once, to make sure no number was missed.
Keep the original, send the copy
The original still contains everything, so store it safely and send only the redacted copy. If the recipient wants to confirm authenticity, they may ask for the original or for your login-verified bank link. Offer that rather than trying to make a redacted file prove itself.
Common mistakes
- Redacting page one and forgetting that page two repeats the account number in the header.
- Screenshotting and cropping, which can leave a larger file with the same sensitive pixels, and looks less credible than the original PDF.
- Leaving the editable original in the same email thread or folder as the redacted copy.
- Over-redacting until the statement proves nothing, so the recipient asks again.
- Redacting a printed copy with a marker and scanning it. Heavy ink on a scan is generally fine, but a thin marker over text can show through when contrast is adjusted.
Is this legal or financial advice?
No. It describes common practice and how PDFs work. Some recipients, such as regulated lenders or immigration authorities, have specific rules about what must be included. Follow their instructions first.
