Add Watermark to Image — Free Online — No Software Required

Add a custom text watermark to photos, graphics, and screenshots before sharing them online. Watermarks discourage unauthorized use, assert copyright ownership, and mark confidential images before distribution. The diagonal placement at the image center is the most effective position — it cannot be cropped out easily. Opacity control lets you balance visibility against content readability. Lower opacity (20-30%) is subtle branding. Higher opacity (50-70%) is a clear copyright or confidentiality mark. Common uses include protecting photography portfolios, marking draft designs for client review, and branding social media images.
