What's hiding in your photos
Every image you take contains hidden metadata. Here's what a typical iPhone photo leaks — and what StripPii removes.
← Tap any field on the left to see what that data reveals about you.
Risk summary
This is a simulation. StripPii processes real files entirely on your device.
Automatic Detection
Drop a file. PII found instantly.
StripPii automatically detects names, ID numbers, phone numbers, addresses, Aadhaar, PAN, SSN, IBAN, credit cards, and more - all processed natively on your device.
Country-Specific Patterns
Built for India and the world.
Built-in patterns for Aadhaar, PAN, UPI, IFSC, driving license, passport, SSN, NINO, IBAN, and more. Enable or disable patterns per region. Add your own custom keywords and regex.
EXIF Metadata
See what's hiding in your photos.
Images carry hidden metadata - GPS location, device model, camera settings, timestamps. StripPii shows you exactly what's there and strips it completely before you share.
Word Documents
DOCX redacted deeper than you think.
StripPii doesn't just redact text in Word files — it strips hidden data too: comments, tracked changes, author name, revision IDs, and embedded objects. Share DOCX files without revealing who reviewed them or how many times they were edited.
Batch Processing
Hundreds of files. One click.
Process multiple files in one go. StripPii analyses all files together, shows a single combined word review, then redacts everything. Pro users can also import entire folders and ZIP archives.
How it works
Four steps to safe sharing
Drop your file
Drop any PDF, image, Word document, or text file. Or scan a physical document with your iPad or iPhone camera.
AI detects PII
StripPii automatically scans your document using on-device AI. Names, IDs, phone numbers, addresses - all found instantly.
Review and confirm
See exactly what was detected. Confirm, skip, or manually add redactions. You are always in control.
Export clean document
Export a redacted version with permanent redactions — choose solid black or blur style. Share with confidence. Original file is never modified.
Detection Engine
Six ways StripPii finds
what you've missed
Most redaction tools run a single pattern match. StripPii runs six detection strategies in parallel — so nothing slips through.
Spatial Pattern Matching
Detects label → value pairs: "Name:", "DOB:", "Account No:" — and automatically flags the information that follows them.
20+ Regex Patterns
Built-in patterns for Aadhaar, PAN, SSN, IBAN, credit cards, NINO, UPI, IFSC, passport numbers, email addresses, and more.
On-device NLP
Apple's Natural Language framework identifies personal names directly on your device — no cloud calls, no data leaving your Mac or iPhone.
Smart Data Detection
Phone numbers, postal addresses, and dates are caught even when they appear without labels or context clues.
Learned Memory
Words you confirm as PII are remembered. The next document with the same name or ID is redacted automatically — StripPii gets sharper as you use it.
Face Detection
StripPii uses Apple's Vision framework to detect and redact human faces in photos, scanned documents, and PDFs.
What people say
Trusted by privacy-conscious professionals
I had been sending Word documents to clients for years without realising they contained my name, internal comments, and full revision history. StripPii stripped all of it in seconds.
HR Manager
Financial Services
Our firm handles hundreds of client contracts weekly. StripPii's batch processing handles them all in one go — and nothing ever leaves our devices. That last part is non-negotiable for us.
Legal Professional
Law Firm
StripPii told me my portfolio photos contained GPS coordinates pinpointing my home address. I had been publishing them publicly for months. I stripped the EXIF data from everything immediately.
