Image Watermark Tool – Add Watermark to Images Online

Easy

Use our Image Watermark Tool to easily add text or image watermarks to your photos online. Protect your images and customize watermark position, size, and opacity quickly.

Image Watermark Tool

Sharing photos online without a watermark makes it easy for someone else to reuse them without credit. This tool lets you add a text watermark (with your own wording, font size, color and rotation) or upload a logo/image watermark, position it anywhere on the photo using presets or free placement, control its opacity, and even tile it repeatedly across the whole image for stronger protection. Everything is rendered live on a canvas so you see exactly what you'll get before downloading — and nothing is ever uploaded to a server.

How to Use Image Watermark Tool

  1. Upload the photo you want to watermark.
  2. Choose "Text" or "Logo/Image" as your watermark type.
  3. For text, type your watermark and adjust font size, color and rotation; for a logo, upload the watermark image.
  4. Pick a position preset (corners, center) or drag the watermark to a custom spot.
  5. Adjust opacity, and enable "Tile watermark" for repeated coverage if desired.
  6. Download the watermarked image.

Features & Benefits

  • Text watermark with custom wording, font size, color and rotation.
  • Logo/image watermark support (upload any PNG/JPG/WebP as the watermark).
  • 9 position presets plus free drag-to-position placement.
  • Adjustable opacity from subtle to bold.
  • Optional tiled/repeated watermark across the entire image.
  • Live canvas preview before download.

Detailed Information

Text watermarks are rendered directly onto the canvas using the native Canvas 2D text APIs, with rotation applied via a canvas transform so the text can run diagonally across the image — a common technique for making a watermark harder to crop out. Logo watermarks are drawn as a semi-transparent image layer on top of the source photo, with opacity controlled via globalAlpha. In tiled mode, the watermark (text or logo) is repeated across the full canvas at a fixed spacing rather than placed once, which is significantly harder for someone to remove by simple cropping. As with all tools here, watermarking happens entirely in your browser, so your original photo is never transmitted anywhere.

Common Uses & Examples

  • Adding a photographer's signature or studio name to proofs before sharing with a client.
  • Placing a company logo on product photos before posting them publicly.
  • Tiling a "Draft" or "Confidential" watermark across a screenshot or exported document image.
  • Protecting portfolio images shared on social media from unauthorized reuse.

Tips & Best Practices

  • A semi-transparent watermark (30–50% opacity) is usually enough to deter reuse without ruining the photo.
  • Diagonal, tiled watermarks are much harder to crop out than a single corner mark.
  • For a logo watermark, use a PNG with transparency so only the logo shape is visible, not a background box.

Privacy & Security

Watermarking is rendered entirely on a local canvas — your photo and your watermark image are never uploaded.

Conclusion

Whether it's a subtle signature or a bold, tiled deterrent, this tool gives you full creative and positional control over your watermark without any software install.
