SimpleMasker

SimpleMasker is a lightweight tool that stamps an exclusive watermark onto your ID photos.

When you submit photos of an ID card, passport, or driver's license, those images can easily be saved and reused by others for purposes you never intended. SimpleMasker lets you quickly overlay a repeating, eye-catching watermark across such sensitive photos — clearly stating the intended use (for example, "For verification only") — so the photo can no longer be repurposed as-is, adding a layer of protection to your privacy.

[Why you need it]
Whenever you hand an original ID photo to an unfamiliar platform, agent, or remote service, it slips out of your control. Marking it with a usage watermark is the simplest, most effective safeguard — it doesn't hide key information, yet strips the photo of any value for secondary misuse.

[Core features]
· One-tap watermark: import or shoot a photo, and a repeating watermark fills the frame instantly.
· Custom watermark text: say whatever you want, like "For review only" or "Do not reuse."
· Full style control: left/right slant, angle, opacity, font size, horizontal/vertical spacing, color, and position are all adjustable.
· Precise cropping: free ratio or common presets — 1:1, 4:3, 3:4, 16:9, 9:16.
· High-res export: set the long-side pixel count and JPEG quality, then export to your gallery.

[100% offline — photos never leave your device]
This app is a purely local tool. All processing — import, crop, watermark, export — happens on your device. No network, no uploads, no personal data collected, and no ad or analytics SDKs integrated. Your ID photos never leave your phone.

[Use cases]
· Submitting ID card, passport, or license photos to platforms and agencies
· Job applications, rentals, and account openings that require identity documents
· Anytime you need to "stamp" a sensitive image with its intended purpose
