Image Tools
Watermark a photo with your name or your logo
Type your name or add your logo, choose where it sits, and watch it land on the picture. Sizes are shares of the image, so the settings that look right here look right at full resolution too.
Add one image, then stamp your name or your logo onto it. Everything updates as you type.

How it works
Everything is a share of the image
The text size, the logo width and the margin from the edge are all proportions rather than pixel counts. This is the difference between a watermark tool you can use and one you cannot: a 40px mark is bold on a thumbnail and invisible on a 6000px photo, so a pixel-based tool has to be re-tuned for every single image.
The outline is what makes it readable
No single colour survives both a bright sky and a dark jacket. A dark stroke under a light mark does, which is why the option is on by default — it is not decoration, it is the only thing that works across a whole photograph.
Tiling is harder to remove
A mark in one corner can be cropped off in seconds. Tiled at an angle across the whole frame it cannot be, without also destroying the picture. That is the trade: a tiled watermark protects better and looks worse, and which you want depends on whether the image is a proof or a portfolio piece.
What it does
Text or a logo
Type a line of text, or load a PNG. A logo with a transparent background sits on a photo far better than one on a white square.
Nine positions, plus tiled
A three-by-three grid of the usual places, and a tile mode that repeats the mark at an angle across the whole image.
Opacity, size and angle
A watermark that cannot be read is pointless and one that dominates the photo is worse. The sliders exist so you can find the line, and the preview means you can see where it is.
The picture never leaves your computer
Everything here is drawn on a canvas in your own browser. There is no upload and no account, and the picture itself is never sent anywhere — which for a photograph of your family, your passport or your unreleased product is the only arrangement worth having. Analytics records that the tool was opened, never what you opened it on.
Practical advice
Getting a better result
- Around 40% opacity is usually the sweet spot: clearly present, not competing with the picture.
- Put a corner watermark where the image is busy rather than in flat sky. Flat areas make it stand out; detail helps it settle in.
- A tiled watermark belongs on proofs and previews. For finished work a single small mark in a corner says the same thing without ruining the image.
- Use a PNG logo with a transparent background. A JPG logo brings its white box with it, and no amount of opacity will hide the edges.
- Save as PNG if the photo has transparent areas you want to keep — JPG will fill them white, watermark and all.
Questions
Things people ask
Will a watermark stop people stealing my photos?
It raises the cost. A corner mark can be cropped out; a tiled one cannot be removed without visible damage. Neither is proof against someone determined and skilled, but both are enough to stop casual reuse, which is most of it.
Can I watermark several photos at once?
Not here — this tool takes one image so the preview shows exactly what you will get. Because every size is a share of the picture rather than a pixel value, the same settings do carry over sensibly to the next image you load.
What opacity should I use?
Start at 40% and adjust while looking at the preview. Below about 20% the mark disappears against a busy background; above about 60% it starts to be the first thing you see.
Does the watermark scale with the image?
Yes. It is sized as a percentage of the picture, so a 6% mark occupies the same visible proportion of a 500px thumbnail and a 6000px original. That is deliberate — it is the reason the settings do not need re-tuning per file.
Is my logo uploaded anywhere?
No. Both the photo and the logo are decoded and drawn inside your browser, and neither is ever transmitted. You can confirm it in your browser’s developer tools — no request carries your images.
