About Image Watermark

A watermark is a visible (or invisible) mark added to an image to identify ownership, prevent unauthorized use, or add branding. Photographers watermark their work with copyright text or logo; businesses add their brand mark to product photos; content creators protect images from being reused without credit. This tool adds text or image watermarks to any photo entirely in your browser using the Canvas API. You control the text, font, size, color, opacity, rotation, and position (9 presets plus custom). You can also tile the watermark across the whole image for stronger protection. Everything runs locally — your photos are never uploaded.

How It Works

  1. Upload or drop your image (JPG, PNG, WebP).
  2. Enter your watermark text (or upload a watermark image/logo).
  3. Adjust position, opacity, size, rotation, color, and font.
  4. Preview live, then download the watermarked image.

💡 Advanced Tips & Pro Insights

  • ▸For opacity, use 30–50% for subtle watermarks, 60–80% for stronger protection. Anything above 90% is distracting.
  • ▸Corner watermarks are less intrusive; tiled watermarks are harder to remove.
  • ▸For best visibility, choose a color that contrasts with the image, or enable the outline/shadow option.
  • ▸For image watermarks, use a PNG with transparency — JPGs will show a colored box.
  • ▸Rotate watermarks diagonally (45° or -45°) for a professional look that is harder to crop out.

Frequently Asked Questions

Is this image watermark tool free?▾
Yes, this image watermark tool is completely free with no signup, email, or usage limits.
Is my data safe?▾
Yes, 100% safe. All watermarking happens in your browser using the Canvas API. Your images are never uploaded to any server.
Can I add a logo as a watermark?▾
Yes. Upload a PNG image with transparency for the best results. The tool places it on top of the base image at your chosen position and size.
What opacity should I use?▾
For subtle, professional watermarks: 30–50%. For stronger protection: 60–80%. Above 90% obscures the image. Start with 50% and adjust.
What is tiling mode?▾
Tiling repeats the watermark in a grid across the whole image. It prevents easy cropping or removal — useful for protecting previews or drafts.
Can I watermark multiple images at once?▾
This tool watermarks one image at a time. For batch watermarking, use a desktop tool like ImageMagick or Lightroom.
Will the watermark be applied permanently?▾
Yes — the watermark becomes part of the image pixels in the output file. Always keep an unwatermarked original.
What output format should I use?▾
PNG for the highest quality (larger file size). JPG for smaller files. WebP for the best balance of size and quality on modern platforms.
