Secure Watermark
Watermark Photos & Documents
Free
Secure Watermark adds a lasting, visible watermark to ID documents and photos — entirely on your device. No network required, no account, nothing uploaded. Protection of privacy is the whole point: your images never leave your iPhone or iPad.
THREE MODES
ID Document Watermark
Photograph both sides of a document and let the app handle the framing. Secure Watermark finds the card edge on device, corrects the perspective and crops it automatically, then lays the front and back out on a single A4 sheet ready for a full-page watermark. If the edges cannot be found, the shot is cropped to the on-screen guide instead. You can import existing pictures instead of shooting. Works with ID Card, Driver License, Social Security Card and Bank Card, and the finished sheet exports as an image or a PDF.
Full-Screen Watermark
Import several photos at once and cover each one with a watermark that spans the whole frame. Built for the moment a picture has to leave your hands: reduce exposure risk before it travels.
Custom Watermark
Pick one watermark from the library and place it where you want it, on a single photo or a whole batch.
THREE WATERMARK TYPES
• Text watermark — build a clean, professional mark with rich text.
• Image watermark — use any image of your own as the watermark.
• Signature watermark — write a handwritten signature and use it as the watermark.
WATERMARK LIBRARY
Every watermark keeps its own look, so choosing one applies it to every photo you export, and ready-made templates give you a starting point. Font, color, opacity, rotation, spacing, margins and alignment are adjustable, and you can save, rename or delete your own watermarks at any time.
PRIVACY
Everything runs on device. Secure Watermark makes no network requests and needs no sign-in, and your pictures are never uploaded anywhere. The photos you capture for ID document mode stay inside the app's own sandbox while you work; only the watermarked result you export is saved to your photo library.
PRO
Pro removes the export limits:
• Export full screen watermark images
• Export certificate images and PDFs
• Export several images at once
• View the preview full screen
Custom Watermark mode exports without Pro, one image at a time. The other two modes need Pro to export.
Built for iPhone and iPad, with an interface in 22 languages.
Your documents, your device.
Ratings & Reviews
A major update: capture and auto-crop for ID documents, a watermark library with ready-made templates, and a redesigned app.
ID DOCUMENT WATERMARK NOW SHOOTS FOR YOU
Photograph both sides of a document and the app finds the card edge on device, corrects the perspective and crops it automatically, keeping a 1.5 mm margin around the card. If the edges cannot be found, the shot is cropped to the on-screen guide instead. Works with ID Card, Driver License, Social Security Card and Bank Card, lays the front and back out on a single A4 sheet, and exports as an image or a PDF.
WATERMARK LIBRARY AND TEMPLATES (NEW)
Text, image and signature watermarks can be saved into the library and reused, each keeping its own design — rename or delete them at any time, and the one you are using right now is shown on the home screen. A new template shelf holds 18 ready-made designs across 7 categories, applied in one tap, and templates can add the date automatically.
A REDESIGNED APP
The home screen now opens on three scenario cards — ID Document Watermark, Full-Screen Watermark and Custom Watermark — each saying what it does. The editor is simpler: pick a watermark from the library, preview it, export.
ALSO IN THIS UPDATE
• Exports that fail now say why, covering photo library access and skipped metadata.
• Exported files are timestamped at the moment you export; capture time is preserved.
• Layout fixes on iPad for the preview and the rename sheet.
• The full screen preview no longer becomes unresponsive while an action panel is open.
• Corrected missing and misplaced copy across all 22 languages.
