A Python library for embedding and extracting blind (invisible) watermarks in images using DWT-DCT-SVD transforms, with watermark recovery not requiring the original image. It provides both a Python API and a command-line interface with password-protected embedding.

Use cases

• embed invisible watermarks in images to prove ownership
• extract a watermark from an image without the original
• add copyright protection to photos before publishing
• detect if an image was stolen from your collection
• batch watermark images from the command line
• hide a text message inside a picture

When to choose

• you need robust invisible watermarks that survive compression and resizing
• you don't have access to the original image when extracting
• you want a simple pip-installable Python or CLI tool for image watermarking

When to avoid

• you need visible overlay watermarks or logos on images
• you require watermarking for video or audio files
• you need cryptographically guaranteed tamper-proofing rather than steganographic marking
