Add a Watermark

Mark a photo with your name or your logo, positioned and faded so it is visible but does not spoil the picture.

1. Choose an image

Both the photo and the watermark are processed in this tab. Neither is uploaded.

Choose the photo to watermark You can also paste an image with Ctrl or Command and V JPG, PNG, or WebP

Choose an image to begin. Nothing is uploaded.

2. Preview

A visible watermark is the one that works. A mark set to 5 percent opacity on a busy photo may be invisible to everyone, including whoever you are trying to discourage. Around 30 to 50 percent in a corner is the usual compromise. If you need to guarantee ownership, keep the unwatermarked original yourself.

Placing a watermark

Keep it out of the middle

A corner survives cropping better than a centre mark, and it leaves the subject of the photo visible.

Use a logo with transparency

A PNG with a transparent background sits over the photo properly. A white rectangle around your logo will not.

Check it small

Zoom the preview out to a quarter size. If the mark is still legible there, it will survive being posted at a thumbnail size.

Text or a picture, and which one to use

A text watermark carries a name, a site, or a copyright line and needs nothing but this tool. A picture watermark takes a logo you have already chosen and lays it over the photograph, which looks more finished and costs you a step. Text is the better choice when the point is attribution; a logo is the better choice when the picture is going somewhere your name is not welcome.

Placement is measured from the image, not guessed

The positions are computed as real fractions of the picture rather than fixed pixel offsets, so the same setting puts the watermark in the same relative place on a phone snapshot and on a large camera file. That is what makes the result usable on more than one picture: you set the position once and it does not creep into a corner on the next, differently shaped image.

Tiling resists being cropped away

A single mark in a corner is one crop away from gone. Tiling repeats the watermark across the whole picture, so removing any one of them means either taking a large piece of the image with it or leaving a visible patch. For a picture you are genuinely worried about, tiling is the stronger choice, and at a low opacity it is less obtrusive than it sounds.

Adjusting the sliders is safe to repeat

Every change redraws the image from the original rather than painting onto what is already there, so dragging the opacity up and down does not stack fifty copies of the mark on top of each other. It is also why the size and position controls stay predictable when you go back and forth: you are always adjusting one mark, not a pile.

Opacity is the whole decision

Low enough to be unobtrusive is high enough to be removable. A watermark at full strength over a detailed area is frequently cropped out by a platform that crops to a standard shape. Somewhere around the point where you can read it without it fighting the photograph is usually right, and tiling makes a lower opacity workable because there is more than one.

It is drawn on, not embedded

The watermark is rendered into the pixels, and the result is a new file. It is not a separate layer, and it cannot be switched off by opening the file in an editor. The trade is that it is also part of the picture permanently, so keep the unwatermarked original somewhere you control.

Check it on the actual device

View the result at the size it will be seen rather than full screen. A mark that reads clearly on a monitor is often illegible in a phone thumbnail, which is the only place most shared photographs are actually looked at.

Making a watermark that survives the places images travel

A watermark is a compromise between visible enough to deter and discreet enough not to ruin the image. Where the image will be seen matters: a small mark near a corner is easy to crop off, while a large semi-transparent mark across the centre is impossible to ignore but interferes with the photograph itself.

Position the mark over something with texture rather than over a flat area such as sky or a plain wall. A mark on a flat region can be painted out or replaced, whereas one that crosses detail is much harder to remove cleanly.

Keep opacity high enough that the mark is legible in a thumbnail. Most viewers first encounter an image at a small size, so test by reducing to the size it will be displayed at before deciding the setting is right.

Understand what any visible watermark can and cannot do. It deters casual reuse and gives you a way to demonstrate provenance later; it does not prevent reuse, because anyone determined can crop, cover, or retouch it. If an image genuinely must not be reused, do not publish the full-resolution version at all.

Common questions

Are my images uploaded?

No. The watermark is drawn in this tab and the finished image is downloaded to your device. Your photos are not sent anywhere.

Does it remove watermarks from other people's images?

No, it adds one. Removing a watermark from an image you do not own is usually unlawful as well as difficult, and this tool does not attempt it.

What should I put in the middle of the picture?

Something small and out of the way. The centre is where the subject is, so a large mark there covers the very thing the photo is of. The corner positions keep it clear of that, and check the result at the size it will actually be seen, because a watermark that looks strong on a large screen disappears on a phone.

Should I use my own logo or text?

A logo with a transparent background sits far more quietly than text, which reads as an accusation rather than a signature. If you do use text, keep it short and low in opacity; the point is to be unremovable by cropping, not to be legible at a glance.

Is the watermark permanent?

It is drawn onto the image and flattened into the pixels, so it becomes part of the file. Your original is untouched, which means you can always go back and change it rather than re-taking the photo.
