What is Image Watermark?

Image Watermark is a free online tool that adds text watermarks to your images. Watermarks help protect your photos from unauthorized use, brand your content, or add copyright notices. The tool offers full control over text, size, color, transparency, and placement.

How to Use Image Watermark

Upload an image by dragging it into the drop zone or clicking to browse. Type your watermark text in the text field. Customize the appearance using the controls: font size, color, opacity (0-100%), and position (center, top-left, top-right, bottom-left, bottom-right, or tiled across the entire image). The preview updates in real time. Click "Download Watermarked Image" to save the result.

How Image Watermark Works

The tool loads your image onto an HTML5 Canvas. The watermark text is drawn on top using the canvas fillText() method with your chosen font size, color, and opacity (set via globalAlpha). For tiled placement, the text is repeated in a grid pattern across the entire image with optional rotation. The final composite image is exported as a downloadable file.

Common Use Cases

  • Protect photographs from unauthorized downloading and reuse
  • Add copyright notices to portfolio images before sharing online
  • Brand product photos with company name or logo text
  • Mark draft or proof images with "SAMPLE" or "DRAFT" text
  • Add photographer credit text to shared images
  • Create tiled watermarks for maximum protection on preview images

Frequently Asked Questions

What position options are available?

You can place the watermark in the center, any of the four corners (top-left, top-right, bottom-left, bottom-right), or tiled across the entire image in a repeating pattern.

Can I adjust the watermark transparency?

Yes. The opacity slider lets you set transparency from fully transparent (0%) to fully opaque (100%). A typical watermark uses 30-50% opacity to be visible without overwhelming the image.

Does the watermark permanently modify my image?

The watermark is applied to the downloaded copy. Your original file is never modified. However, the downloaded watermarked image does have the text permanently embedded — it cannot be easily removed.

Can I add an image/logo watermark?

This tool supports text watermarks only. For image-based watermarks (logos), you would need a more advanced image editor.
