How to Blur ID Cards, Passports, and Bank Cards in a Photo

Steps

1. Open PrivShot and import the photo of the ID, passport, or bank card.
2. PrivShot scans it and blurs the sensitive numbers it detects automatically.
3. On the review screen, toggle whole-document blur if you want to cover the entire card or document, not just the printed numbers.
4. Brush over anything else by hand — a signature, a stamp, a photo on the ID.
5. Tap Export to save the redacted copy; location metadata is stripped too.

Why it works this way

Sending a photo of an ID or bank card is one of the riskiest things people do in chat apps. PrivShot runs the detection on-device, so the un-redacted document is never uploaded to a server to be “read.” The whole-document option exists because sometimes the safest choice is to cover the entire card, not trust that every field was caught.

Tips & edge cases

• Prefer whole-document blur for anything you don’t fully trust the recipient with. It’s the belt-and-suspenders option.
• Glare or a skewed angle can make small print harder to detect — check the review screen and brush over anything the scan didn’t cover.
• The brush only adds. You can’t accidentally un-blur a number once it’s covered.

FAQ

Can it hide just the number, or the whole card? Both. PrivShot detects the sensitive numbers automatically, and you can also switch on whole-document blur to cover the entire ID or card.

Which documents does it recognize? ID and passport numbers, bank card numbers, and company credit codes, alongside faces, phone numbers, and addresses.

Is the original ever uploaded to check the numbers? No. Detection runs entirely on-device — the photo of your document never leaves your phone.
