Jak używać Auto-Redact PII
Automatically locate and permanently redact emails, phone numbers, SSNs, credit card numbers, and custom keywords across PDF pages.About auto redact PDF
Automatically locate and permanently redact emails, phone numbers, SSNs, credit card numbers, and custom keywords across PDF pages. Prepare medical records, discovery documents, bank statements, or HR files for external sharing without manually drawing dozens of redaction boxes.
Automatic detection relies on the selectable text layer. Handwritten notes or scanned images without OCR must be OCRed first or redacted manually with Redact PDF.
How PDFolio helps you auto redact PDF
PDFolio inspects every text item and its bounding coordinates via PDF.js, matches selected PII regex patterns and custom terms, renders affected pages to high-resolution images with solid black redaction boxes, and rebuilds the PDF without the underlying text layer.
To black out a fixed rectangular region on a scanned image page, use Redact PDF.
Before you download
Always visually review every page of the downloaded PDF to confirm no sensitive text remained outside the matched patterns.
When the result is ready, download it immediately and open it in your usual PDF viewer to make a final check. You can then use Clear task data to release temporary file references from this browser tab. PDFolio does not create an account, cloud folder, or server-side document history.
A private way to auto redact PDF
PDFolio handles the selected files in the active browser tab. A Web Worker on your device performs the PDF task so the interface can remain responsive; document bytes are not sent to a PDF processing server, upload queue, account database, or advertising platform.
Kroki
- Add a PDF containing sensitive personal information.
- Choose which PII patterns to redact (Emails, Phones, SSNs, Credit Cards) and enter any custom names or account numbers.
- Process locally and inspect the redacted PDF before sharing.
Warto wiedzieć: Pages containing matches are rasterized after black boxes are painted over the text so the underlying text layer is completely destroyed.
Najczęstsze pytania
Can someone copy-paste the text from under the black boxes?
No. Every page where a redaction occurs is flattened into a bitmap image after painting the black boxes, permanently removing the underlying text stream.
How can I remove SSNs, Aadhaar numbers, PAN numbers, or account IDs from a PDF?
Enable the built-in PII detectors or enter specific IDs/names in the Custom words or IDs field. Auto-Redact PII locates every occurrence and permanently blacks it out locally with no watermark.
Can I redact specific client names or account numbers?
Yes. Enter comma-separated names or terms in the Custom terms field.
Does auto redact PDF change my original file?
No. PDFolio creates a new file for download. Your source file remains unchanged on your device.
