A Python library and command line tool for embedding and decoding invisible (blind) image watermarks that do not require the original image for extraction. It supports frequency-domain methods (DWT+DCT variants) and a deep-learning-based RivaGAN method.

Use cases

• add invisible watermarks to images for copyright protection
• embed a hidden watermark in AI-generated images on the fly
• decode a blind watermark from an image without the original
• watermark images in bulk from the command line
• protect stock photos or posters with steganographic marks

When to choose

• you need a lightweight Python library for blind image watermarking
• you want fast on-the-fly watermark embedding on CPU with the dwtDct method
• you prefer a simple pip-installable tool with both library API and CLI

When to avoid

• you need guaranteed 100% accurate watermark decoding
• your images are web screenshots or posters with homogeneous backgrounds
• you need GPU acceleration or production-grade robustness against attacks
• you need fast embedding of large images with the slower rivaGan method
