Watermark images
Put your name, a note or your logo on a photo, also on many images one after another.

JPG · PNG · WEBP · STAYS ON YOUR DEVICE
At most 60 characters, one line. On copies of ID cards and contracts, add the purpose, for example “Only for rental contract 3 Sample Street”.
The font used is the one available on your device. In the finished image, it is then fixed.
Ideally use a PNG with a transparent background. JPG and WebP work too, but then a visible box sits on the photo.
Without a shadow, white text disappears in the sky and black text in the shade.
Measured as a share of the shorter image side: this way the watermark sits the same distance from the edge in portrait and in landscape.
The watermark repeats across the whole image. At an angle it is harder to crop off, so the watermark rotates on its own when you switch.
Each image comes out in the format it came in. Quality applies to JPG and WebP; PNG is always saved lossless.
The preview shows the first image, scaled down. All settings are shares of the image size: so every image gets its watermark in the same spot and at the same size, no matter how large the image is.

How it works
- 01Choose images or drag them into the box.
- 02Type a text or load your logo, choose spot and size, and the preview shows it right away on the first image.
- 03Tap “Add watermark”. Then download each image on its own or all together as a ZIP. Your originals stay unchanged.
What it is good for: Quote and product photos with your company name, construction site photos with job and date, images for your own website with “© Your Name”. And copies of an ID card, proof of address or pay slip with “Only for apartment application 3 Sample Street”: anyone who later sees the copy somewhere else can tell right away that it does not belong there.
What a watermark can and cannot do: It shows who an image is from and what you gave it out for. It does not stop anyone from passing the image on. Cropping it off, covering it or retouching it away is possible, easy with a mark in the corner, harder with a tiled one. A copy of an ID card does not become safer this way, it only becomes harder to use for something else.
Tiled: The watermark repeats at an angle across the whole image. It then gets in the way of the subject, but it can no longer simply be cropped off. For copies of ID cards, this is the better choice.
Format and size: Each image is redrawn at its full resolution and saved in its own format. GIF and BMP come out as PNG, AVIF and HEIC as JPG, because no browser can write these formats. Because the image is redrawn, GPS, camera and other metadata are dropped. The file can end up larger or smaller than before; the list shows both sizes side by side.
Limits: Only one image is processed at a time, so a long list takes correspondingly long. The bar shows how far it has got. Some phone browsers cannot handle very large images (well over 20 megapixels); the row in the list then says so, and you make the image smaller first with Resize images. Only Safari can open HEIC photos from an iPhone; otherwise set your iPhone to “Most Compatible”. The text stays on one line, there are no line breaks here.
