What is a Watermark?

A watermark is a visible or invisible mark placed on images, documents, or other media to indicate ownership, authenticity, or to discourage unauthorized use. Digital watermarks have become essential tools for photographers, designers, and content creators to protect their work.

Brief History

Watermarks originated in 13th-century Italy as marks on paper during manufacturing. Today, digital watermarks serve the same purpose of proving ownership and authenticity, but on digital media.

Types of Watermarks

Common watermark types include text (copyright notices, names), logos (brand marks), patterns (tiled watermarks), and invisible watermarks (metadata). Each serves different protection and branding needs.

Best Practices

Effective watermarks balance visibility with aesthetics. Place them strategically (corners or center), use appropriate opacity (30-70%), and consider tiling for maximum protection without ruining the image.
