Watermark images online with custom text

Protecting your images with text watermarks

Watermarking adds a visible overlay to images that identifies the creator, deters unauthorized use, and maintains brand presence even when images are shared without attribution. For photographers, designers, and content creators, watermarks are a practical compromise between sharing work publicly and protecting intellectual property.

Effective watermarks are visible enough to deter theft but subtle enough not to ruin the viewing experience. Semi-transparent text at 30-50% opacity, positioned in a corner or across the center, achieves this balance. The text should include your brand name, website URL, or copyright symbol — something that identifies you without dominating the composition.

Position matters for watermark security. Corner watermarks are easy to crop out, so they work best as branding rather than theft prevention. Center-positioned or diagonally repeated watermarks are much harder to remove because they overlap the main subject. Choose your position based on whether you prioritize aesthetics or protection.

This tool bakes the watermark directly into the pixel data during export. Unlike metadata-based watermarks that can be stripped, a pixel-level watermark is permanent — it cannot be removed without visibly damaging the image. This makes it suitable for portfolio previews, client proofs, and stock photo samples.

Common use cases

• Photography portfolio protection: Add your studio name or website URL to portfolio images shared on social media, preventing unauthorized commercial use while still showcasing your work.
• Client proof delivery: Watermark preview images sent to clients before payment, ensuring they cannot use the full-quality versions without completing the transaction.
• Stock photo samples: Apply diagonal repeating watermarks to stock photo previews that buyers can evaluate but not use commercially without purchasing the clean version.
• Brand consistency in shared content: Add consistent branding to all images shared by your marketing team, ensuring your company name travels with every visual asset across platforms.

Technical details

9-point positioning

Choose from top-left, top-center, top-right, middle-left, center, middle-right, bottom-left, bottom-center, or bottom-right placement for precise control.

Opacity control

Set transparency from 0% (invisible) to 100% (fully opaque). Values between 30-60% typically provide good visibility without overwhelming the image content.

Font and size

The watermark uses the system sans-serif font rendered at your chosen pixel size. Larger sizes are more visible and harder to remove but more intrusive.

Permanence

The watermark is drawn directly onto the Canvas pixels before export. It becomes part of the image data and cannot be separated or removed as a layer.
