PDFs containing credit card numbers create serious security and compliance risks. Whether it is a receipt, an expense report, or a financial document, exposed card numbers in shared PDFs can lead to fraud and PCI-DSS violations. Our free tool permanently removes card numbers from PDFs — with no server uploads ever.
- PCI-DSS compliance requires that card numbers are never shared in unprotected documents
- Expense reports and receipts often contain full card numbers that must be removed before sharing
- Emailing or uploading PDFs with card numbers exposes them to interception and breach
- Simply blacking out card numbers in a PDF editor may not remove the underlying text data
How to Redact — 3 Simple Steps
Open Your PDF
Select the PDF containing credit card numbers. It loads in your browser — never uploaded anywhere.
Search & Redact or Draw Box
Use Search & Redact to find card number patterns, or draw a redaction box precisely over the card number if it is in an image or non-text area.
Download Redacted PDF
Download the permanently redacted PDF. Card number data is deleted from the file — not just visually hidden.
Key Features
🔒 Your Files Never Leave Your Device
Unlike tools that upload your PDFs to remote servers, our tool processes everything locally in your browser using WebAssembly. No server ever sees your documents — not even us. This makes it one of the most private PDF tools available, completely free.
Frequently Asked Questions
Does this work on receipts where the card number is printed?
Yes — for printed or scanned receipts, use the draw redaction box tool to cover the number. For digital PDFs with a text layer, use Search & Redact.
Can I redact partial card numbers like the last 4 digits?
Yes — draw a box over precisely the portion you want to remove, leaving the rest visible.
Is the card number truly gone from the file?
Yes — our tool permanently deletes the underlying data. The number cannot be recovered by selecting, copying, or inspecting the PDF file.
Will this satisfy PCI-DSS requirements for document handling?
Our tool creates permanent redactions that remove underlying data. For full PCI-DSS compliance, consult your compliance officer about document handling policies.
