# 🖼️💧 Image Invisible Picture Watermark API

The **Image Invisible Picture Watermark API** allows developers to imperceptibly embed and later extract image-based watermarks into/from digital photos using advanced AI models. It supports multiple watermarking models for varying levels of security and robustness, with flexible encoding and decoding modes.

Whether you’re protecting digital artwork, embedding invisible brand logos, or verifying ownership of visual content, this API ensures that embedded watermarks do not degrade image quality while remaining retrievable when needed.
