Watermark Tool — Your Privacy-First Image Processing Expert

“Watermark Tool” is a professional image editing application designed for photographers, content creators, and privacy-focused users.
We understand the importance of your photo privacy, which is why all core features — from AI-powered watermark removal to signature extraction — are processed completely offline on your device, with zero cloud upload.

Core Features:
1. Intelligent Offline AI Watermark Removal
AI + OpenCV Dual Engine Restoration:
Combines advanced AI-based image understanding with OpenCV Inpaint (Telea / NS) algorithms to intelligently detect watermark areas and reconstruct missing pixels naturally, even on complex backgrounds.
Fully Offline AI Processing:
All watermark removal is performed locally on your device, requiring no internet connection and ensuring complete privacy.
High-Resolution Output:
Processing is based on the original image resolution, preserving clarity and avoiding blur.
Simple Operation:
Supports rectangle selection and manual brush tools. AI automatically triggers the restoration process instantly.
2. Exclusive Handwritten Signature Extraction
From Paper to Digital:
Simply write your signature on paper, take a photo, and the app uses AI-assisted recognition to extract your handwriting and generate a transparent digital signature watermark — fully offline.
Personal Stamp:
Easily overlay your unique signature onto photos to protect copyright and enhance professionalism.
3. Invisible Watermark Copyright Protection
DCT Steganographic Watermark:
Uses frequency-domain encryption to embed invisible copyright information. It is not visible to the human eye but can be extracted and verified within the app when needed, providing deep protection for your original content.
4. All-in-One Watermark Editor
Text & Image Watermarks:
Rich gradient presets, 3D-style effects, and custom image watermark support.
Custom Fonts:
Import your favorite TTF/OTF fonts for full personalization.
Flexible Layout:
Drag, rotate, scale, adjust opacity, and apply full-image tiling modes.
