Why should I watermark my images?

Watermarks protect your copyright, deter image theft, and promote your brand when images are shared on social media or used by others.

What opacity should I use for a watermark?

30–50% opacity creates a professional, unobtrusive watermark that protects your image without distracting from it. Use higher opacity for more prominent branding.
