Image Watermark

Add a text watermark to your photos right in your browser.

ToolsSoup's Image Watermark is a free online tool that stamps a custom text watermark onto your photos and pictures right in your browser. Protect your work with a copyright notice, brand your images with your name or website, or mark a draft — then download the result in seconds, with no uploads, no extra watermarks, and no sign-up. Your images never leave your device.

What is an image watermark?

An image watermark is text or a logo laid over a picture to show who created or owns it. A clear, semi-transparent caption such as a name, copyright line, or website discourages others from reusing your work without credit and helps people trace an image back to you. This tool draws your chosen text directly onto the photo on an HTML canvas, so the watermark becomes part of the exported file rather than a separate overlay.

How to add a watermark to an image online

Watermarking a photo with ToolsSoup takes just a few seconds:

  1. Click Choose an image and select the photo you want to watermark.
  2. Type your watermark text, then pick a position, size, color, and opacity.
  3. Turn on Tile (repeat) if you want the watermark stamped diagonally across the whole image.
  4. Choose an output format (PNG, JPEG, or WebP), click Add watermark, and download the result.

Tiled watermarks for stronger protection

A single corner watermark is easy to crop out, so for images you really want to protect, enable Tile (repeat). The tool then stamps your text diagonally across the entire picture at a low opacity, making the mark much harder to remove without damaging the photo. Lower the opacity so the watermark stays readable but does not overpower the image, and bump up the text size on large photos so it remains legible after resizing for social media.

Frequently asked questions

Is this image watermark tool free?

Yes. Every tool on ToolsSoup is completely free to use, with no account, sign-up, hidden watermarks, or usage limits.

Are my images uploaded to a server?

No. All watermarking happens locally in your browser using the HTML canvas, so your images are never uploaded, stored, or seen by anyone but you.

Will the watermark lower my image quality?

The watermark is drawn over your image at its original resolution, so the dimensions stay the same. PNG output is lossless, while JPEG and WebP apply their normal export compression.

How do I make a watermark harder to remove?

Enable the Tile (repeat) option so the text is stamped diagonally across the entire image. A repeated, semi-transparent watermark is much harder to crop or paint out than a single mark in one corner.

What image formats are supported?

You can load common formats such as JPG, PNG, and WebP, and export the watermarked result as PNG, JPEG, or WebP.
