About This Tool

How to Add a Watermark

  1. 1Drop or select the image you want to protect.
  2. 2Choose a text watermark (type your name, URL, or copyright notice) or upload a logo/image watermark such as a transparent PNG.
  3. 3Set position, size, and opacity. Lower opacity (20–40%) is less intrusive but still effective; higher opacity (60%+) is better for strong protection.
  4. 4Preview the result, then Download your watermarked image. Everything runs locally — your photos never leave your device.

When to Watermark an Image

Photography Portfolios
Protect your work when sharing online. Our guide on how to watermark photos effectively covers placement, opacity, and what most photographers get wrong.
E-Commerce Product Images
Add brand or URL watermarks to product photos before posting to marketplaces to prevent competitors from copying your imagery without attribution.
Client Proofs & Previews
Send watermarked previews to clients before final delivery to protect full-resolution work until payment is received — a standard practice in photography and design.
Social Media Content
Brand your images before sharing so attribution travels with the photo as it gets reshared. Pair with our Social Media Resizer to nail platform dimensions first.

Why Watermark in the Browser

Client photos, portfolio shots, and confidential product imagery are exactly the kind of files you don't want passing through an unknown server. This tool processes everything locally using the Canvas API — nothing is uploaded. For a complete image protection workflow, consider pairing watermarking with our EXIF Viewer & Remover — watermarks protect visual attribution while EXIF removal strips location and device metadata you may not want embedded. If your images also need a consistent visual treatment before watermarking, our Add Border and Image Filters tools complete the workflow without leaving the browser.

Frequently Asked Questions

It depends on the purpose. For copyright protection where you want the watermark clearly visible, 40–60% opacity works well. For subtle branding that doesn’t distract from the image, 15–30% is more appropriate. The tiled option at low opacity (10–20%) is the hardest to remove while staying visually clean.

Use a PNG with a transparent background for best results. A white or black logo on a transparent PNG blends naturally with any image. SVG files also work well. Avoid JPG for watermark logos as it doesn’t support transparency and will show a rectangular box around your logo.

No — the watermark is composited onto the image using the Canvas API at high quality. The download uses 93% JPG quality (or lossless PNG if your original was PNG), so the base image quality is preserved. Only the watermark layer is added on top.

A tiled (repeated) watermark across the entire image is much harder to remove than a single watermark in one corner. With a corner watermark, someone can simply crop the image. With a tiled pattern, removing it would require significant editing work that destroys the underlying image. Tiled watermarks at 10–20% opacity provide strong protection while remaining unobtrusive.

The output format matches your original image. JPG images download as JPG, PNG images download as PNG (preserving transparency). The watermark is permanently embedded in the image data — it cannot be removed without re-editing the file in image editing software.
