Runs in your browser — your file never leaves your device.

Stamp text such as a copyright line or a client name onto an image, in your browser, without uploading it. Watermark Image places your text in a chosen corner or the centre at an opacity you set, so the mark is visible without ruining the picture. It is the quick way to brand a set of proofs or put a visible notice on a photo before sending it out.

How to use Watermark Image

Click "Select image files" and choose the picture.
Type your watermark text. It defaults to a copyright line, but any short phrase fits.
Choose a position — bottom right is the usual place for a copyright notice, and centre is the hardest to crop out.
Set the opacity. 50% is visible and still lets the image read; raise it for a proof you want no one to use.
Click "Watermark Image" and download.

Who it is for

Watermark Image is for putting a visible notice on a picture before it goes out: a copyright line on proofs sent to a client, a photographer's name on a preview, or a "sample" mark on a design you do not want used uncredited. It is also used to mark internal screenshots that should not be shared.

How it works

The text is drawn into the pixels at the position and opacity you choose, so it travels with the image and cannot be switched off from a layers panel.
The text size scales with the image, which keeps the mark at a consistent proportion of the frame across different sizes.
Five positions are offered, and the centre is the hardest to crop out afterwards.

What it cannot do

Text only — no logo image. Placing a logo needs an editor, which this site does not offer as a browser tool.
A mark in a corner can be cropped off; a mark over the centre has to be cloned out, which is slower but not impossible.
The colour is fixed to a light fill with a dark outline, so it may read poorly on a busy or very light background.
It is a deterrent, not protection: the original is unchanged, so anyone with the source has the unmarked version.

Frequently asked questions

Can I use my own logo instead of text?

Not with this tool — it sets text only. To place a logo you would need an image compositor, which this site does not offer as a browser tool.

Does the watermark sit on the image or in a separate layer?

It is drawn into the pixels, so it is part of the image and cannot be removed by hiding a layer. It can still be cropped off if it sits in a corner, which is why the centre position exists.

Will it look the same on every image size?

Yes, in relative terms: the text is sized from the image, so it keeps the same proportion of the frame whether the picture is a thumbnail or full size. Only a very small image hits the minimum size the tool allows. Check a sample before running a batch.

Is the watermark easy to remove?

No, but it is not impossible. Drawn into a corner it can be cropped; drawn over the middle it has to be cloned out, which is slow and leaves traces. For a deterrent rather than real protection, that is enough.

Are my images uploaded?

No. The drawing happens on your device, so nothing is transmitted.
