Watermark an Image

Write your name, a copyright line or a “sample” mark onto a picture, so it travels with the file wherever it goes.

How to use it

Add your pictures

Drop the images above or click to browse. The same mark is applied to each, so a whole set can be branded in one pass.

Type the watermark

A short line works best — a name, a website, "© 2026", "SAMPLE". A long sentence at a large size will run past the edge of the frame.

Choose where it sits

A corner keeps the picture readable. Tiling repeats the mark diagonally across the whole image, which is much harder to crop out.

Tune the strength

Open Advanced options to change size, opacity and colour. White at about half opacity sits well on most photos; pick a dark colour for a pale picture.

Download

Each marked picture is saved with "-watermarked" in its name. The originals are untouched.

Common issues

The text is unreadable on a busy photo

The mark lands on whatever is behind it. Raise the opacity, switch to a contrasting colour, or tile it so some repeats fall on plain areas.

Text is cut off at the edge

The line is longer than the picture is wide. Shorten it or lower the size in Advanced options.

The mark disappeared when saved as JPEG

White at low opacity on a white background is invisible. Check the picture and adjust colour or opacity.

Transparency turned white

JPEG has no transparency. Choose PNG or WebP if the picture needs it.

Frequently asked questions

Should I use a corner or a tile?
A corner mark keeps the picture looking clean but is easy to crop off. Tiling covers the whole image and is much harder to remove, at the cost of a busier look.
What opacity should I choose?
Around 0.5 is a good starting point: visible without hiding the picture. Lower it for something subtle, raise it when the watermark is a formal notice.
Which colour works best?
White shows on dark areas and a dark tone shows on pale ones. If the picture has both, a tiled mark at moderate opacity usually reads on either.
Can I use an image or logo as the watermark?
Not here — this tool writes text. For documents, a logo can be layered on with Overlay PDF.
Will the watermark survive editing?
It is drawn into the pixels, so it travels with the file. A corner mark can still be cropped away, which is the argument for tiling.
Can I watermark many photos at once?
Yes. Add as many as you like and the same text and settings are applied to each.
Why does my long text run off the edge?
The size is a share of the image width, so a long line at a large size ends up wider than the picture. Shorten the text or lower the size.
Does the watermark reduce quality?
The picture is re-encoded once, so there is a normal amount of compression. Keep the quality setting high to minimise it.
Is anything uploaded?
No. The mark is drawn and the file is saved on your own device.
