How to Add Text Watermark to Image Online

A text watermark is the simplest and most immediately effective form of photo protection. Your name, website URL, or copyright notice stamped directly on your image takes seconds to add but travels with the photo indefinitely — wherever it's shared, posted, or reused. Text watermarks are also easily readable by both humans and search engines, providing passive attribution whenever your image appears online.

What Text to Use as a Watermark

The most effective text watermarks are clear, concise, and directly identify you or your business. Options include: your full name (for personal photographers), your website URL (e.g. imgresizr.com — easily memorable and searchable), your business name, or a copyright line (e.g. © 2025 Your Name. All Rights Reserved.). Website URLs work particularly well because anyone seeing the watermark knows exactly where to find more of your work.

How to Add a Text Watermark Online

1. Open the Watermark Tool at imgresizr.com.
2. Upload your photo.
3. Select Text Watermark and type your watermark text.
4. Choose a font, size, and colour — white text is most universally visible; semi-transparent works on all backgrounds.
5. Position the text — bottom right is the conventional location for non-intrusive watermarks.
6. Set opacity to 50–70% and download.

Text Watermark Design Tips

Use a Simple, Readable Font

The most effective watermark text uses a clean, readable font — not a decorative or script font that's hard to read at small sizes. The watermark needs to be legible at thumbnail size, so choose a sans-serif font like Arial, Helvetica, or a simple serif that remains clear when the image is viewed small on a social media feed.

Contrast Makes It Work

White text with a subtle drop shadow is the most universally visible watermark because it shows up on both light and dark backgrounds. If you're always watermarking photos with a specific tone (e.g. light outdoor shots), you can use a more specific colour. But for versatility, white with 50% opacity works on almost everything.
