How do I redact personal information from a PDF?
GoSmart PDF's PII Detection automatically scans your PDF for names, phone numbers, email addresses, Aadhaar numbers and other sensitive data. Tap PII Detect, run the scan, review the results and tap Redact. The selected information is permanently removed — not just covered up.
Does GoSmart PDF upload my files to a server?
