How to Blur a QR Code in a Screenshot on Mac (2026)
Auto-blur QR codes in Mac screenshots before sharing: protect boarding passes, 2FA codes, tickets. Free, on-device, one click. Step-by-step guide.
QR codes are dangerous to screenshot. They encode URLs, plane tickets, 2FA backups, restaurant orders, building access, and almost everyone shares boarding pass screenshots in iMessage groups without thinking.
Here’s how to protect them on Mac.
Step-by-step
Step 1: Open the screenshot in Pizazoo
Find the screenshot containing the QR code in your library, open it (Return or Space opens the preview), then click Edit to open the markup editor.
Step 2: Click "Blur QR codes"
In the privacy section of the markup toolbar, click Blur QR codes. Pizazoo runs Apple Vision’s on-device barcode detector and blurs every QR code it finds.
Step 3: For real secrets, use Redact instead
Blur can be reversed by some image-recovery tools. For genuinely sensitive QR codes (boarding pass, 2FA backup), pick the Redact tool and drag a solid block over the code instead.
Step 4: Save and share
Click Done to apply it. Pizazoo keeps the pristine original, so you can reopen the editor later and change or remove the blur. To keep both versions, open the Done menu and choose Save a copy. Use Share to send it via Mail, Messages, or any macOS share target.
Why not just crop the QR out?
Cropping is fine when the QR is at the edge of the screenshot. When it’s in the middle (e.g. a screenshot of a checkout page), cropping destroys the rest of the context. Redact is the right tool.
