### "Protect your AI illustrations. Watermark it easily, offline and smart."

WaterMarker is a lightweight, standalone Windows application designed to batch-watermark your illustrations and AI-generated images with 100% privacy.

The ultimate strength of this tool is its Smart Skin-Tone Detection. It automatically analyzes character skin and faces so that your logo or signature never covers the most important part of your artwork.

Runs completely locally on your PC. No internet connection, no API keys, and no data tracking—your valuable images never leave your local environment.

💡 Key Features

1. Smart Skin-Tone & Busyness Detection

Using the YCbCr color space, the app automatically calculates skin pixel density on both sides of the image. It shifts your logo to the opposite side to keep character faces and bodies clean. If skin tones are low, the "Busyness Detection" algorithm kicks in to avoid busy backgrounds. Manual positioning (Bottom-Right, Bottom-Left, Top-Right, Top-Left) is also available.

2. High-Speed Batch Processing with "Instant Cancel"

Simply specify your input folder, logo image, and output folder to start processing the entire directory in the background. If you need to stop, just click the "⏹ Cancel" button to safely interrupt the process after the current image finishes.

3. Seamless Resume via "Smart Skip"

By default, if the output directory already contains a file with the same name, the app automatically skips it. This makes it incredibly easy to resume where you left off if you canceled the process. You can also check "Overwrite Existing Files" to force-update everything.

4. Broad Format Support & Clean Output Conversion

Fully supports reading PNG, JPG, JPEG, WebP, BMP, TIF, and TIFF formats, even if they are mixed in the same folder. All images are automatically converted and saved into clean PNG or JPG formats. You can intuitively adjust logo size, opacity, rotation, padding, and JPG quality via sliders.

⚠️ Important Notes

- False Positives from Antivirus

Because this app is compiled into a single executable file using PyInstaller, Windows Defender or other antivirus software may flag it as a false positive upon launch. The app is completely safe and runs entirely offline, but if you are concerned, please feel free to scan it via VirusTotal before use.

- Support & Refunds

Due to the nature of digital goods and independent development, all sales are final, and individual technical support cannot be provided. Please make sure to test your system compatibility with the free Lite version before making a purchase.
