Why Should You Watermark Your Images?

• Protect your photos from unauthorized use

• Brand your product images with your logo

• Prevent competitors from stealing your content

• Build brand recognition across all your photos

• Mark ownership before sharing on social media

Text Watermark vs Logo Watermark — Which is Better?

Text watermarks are simple and fast. You just type your name, website, or copyright notice. Logo watermarks look more professional and are harder to remove. For businesses, a logo watermark is always the better choice. For personal use, text watermarks work perfectly fine.

Tips for Best Watermarking Results

• Use semi-transparent watermarks so they do not block the main image

• Place watermarks in a corner for a professional look

• Use white or light-colored text on dark images and dark text on light images

• Test with one image before processing in bulk
