Why Add Watermarks to Photos?

Watermarks protect your photos from unauthorized use and help identify your work when it's shared online. Photographers add watermarks to portfolio images to prevent theft while still showcasing their work. Designers add watermarks to mockups and previews before client approval. Content creators add watermarks to social media images for brand recognition. A subtle watermark in the corner is enough to deter casual theft while keeping the image visually clean.

Watermark Best Practices

For portfolio images, place the watermark in the bottom-right corner at 50-70% opacity. Use white or light gray for dark images, dark gray for light images. Keep the text short — your name or website URL is ideal. Avoid placing watermarks in the center as it ruins the composition. For social media, a subtle corner watermark is less intrusive than a large centered one. Consider using your website URL as the watermark text for free advertising.
