How to Watermark Photos With Your Logo (Without Ruining Them)

A watermark does two jobs: it brands every photo you publish, and it protects work you share before payment. The trick is doing both without wrecking the image - and without paying for bloated desktop software.

Frequently asked questions

Does the tool resize my photos?

No - photos keep their original dimensions. Only the watermark is scaled, relative to each photo's width, so a batch of mixed sizes gets a consistent look.

Is there a limit on the number of photos?

No hard limit - everything runs locally in your browser. Batches of 50+ photos work fine on a typical laptop.

Watermark settings for different jobs

The right watermark depends on why you are adding it: brand recognition on shared images, or protection for proofs you do not want reused. The settings below are sensible starting points.

PurposePositionSize (% of width)Opacity
Subtle branding on social or portfolio photosBottom-right or bottom-left corner10–15%40–60%
Product photos for marketplacesCheck the marketplace rules first — many prohibit watermarks on main images——
Client proofs (photography, design)Tile across whole image15–25%20–35%
Real-estate and listing photosCorner12–18%50–70%

Use a transparent, single-colour logo

A logo with a white box looks like a sticker. Start from a transparent PNG — the Background Remover can make one — and consider a white version for dark or colourful photos using the Logo Color Changer. White logos at 50–60% opacity sit well on most images.

Size as a percentage keeps batches consistent

Because size and margin are percentages of each photo’s width, a batch of mixed resolutions — phone photos and DSLR images — gets a watermark that looks the same on every image. Exports are full resolution; the preview only shows the photo selected in the strip.

What a watermark can and cannot do

Corner watermarks mainly build recognition when images are shared; they can be cropped out. Tiled watermarks are much harder to remove and suit proofs, at the cost of spoiling the image for normal viewing. No watermark is a legal protection on its own — your copyright exists regardless — but it reminds people who made the image. For video, see our video watermark size guide.
