PlateGuard: Plate & Face Hider

Hide license plates, faces, QR codes and addresses in one tap — before you post.

PlateGuard auto-detects license plates, faces, QR/barcodes and sensitive text (phone numbers, addresses, tracking codes) in your photos and lets you mask them with fill, blur, mosaic, emoji stamp, or a stylish "PRIVATE" plate replacement — a free photo editor designed for the moments before you list or share.

Marketplace listings (Mercari, eBay, Yahoo Auctions, Facebook Marketplace), social car shots (Instagram, X, TikTok), YouTube thumbnails, dealer inventory pages, blog reviews — the "one extra step before posting" should never be a chore again.

■ What it does

• Auto-detects plates, faces, QR/barcodes, and sensitive text

• 5 mask modes — fill, blur, mosaic, emoji stamp, PRIVATE plate replace

• Different mask per region (e.g. blur the face, replace the plate)

• Guide box appears even when auto-detect fails — just drag it

• Tap-to-refine, drag corners, re-detect, delete false positives

• Batch process multiple photos at once (rewarded-ad unlock)

• Strips GPS and other EXIF metadata on save

• Post-save audit report so nothing slips through
