How to Add a Watermark to an Image

To add a watermark to an image, open the Watermark Adder, upload your photo, type your text or drop in a logo, then set the position and opacity and download the result. The whole thing runs in your browser, so your original never leaves your device. Below is how to choose the settings that actually deter theft.

Text watermark vs logo watermark

Both mark an image as yours. Pick based on what you are protecting:

Text watermark: your name, studio, website, or a copyright line. Fast, scalable, and readable at any size. Best for photographers and writers.
Logo watermark: your brand mark as a semi-transparent PNG. Best for stores and designers who want consistent branding across a catalog.

If you only need one, text is the simpler choice. A logo wins when brand recognition matters more than a literal credit line.

Placement and opacity that hold up

Where you put the mark is a tradeoff between subtlety and security.

Corner: the most common spot. Subtle and out of the way, but also the easiest to crop off.
Center: harder to ignore, but it sits on the subject and hurts how the image looks.
Tiled across the whole image: the hardest to remove because someone would have to edit every repetition. Use this for proofs and previews where protection beats polish.

Opacity decides whether the watermark is visible without ruining the image. A good range is 30 to 60 percent. Below 30 percent it disappears against busy backgrounds; above 60 percent it dominates the photo. Start at 40 percent and adjust while you watch the preview.

Add a watermark in four steps

Open the Watermark Adder and upload the image you want to mark.
Choose text and type your credit line, or switch to logo and add a transparent PNG.
Set the position (corner, center, or tiled) and drag opacity to roughly 30 to 60 percent.
Preview the result, then download the watermarked copy. Your original file stays untouched on your device.

Everything happens locally in the browser. Nothing is uploaded to a server, so even confidential client work is safe to mark here.

What a watermark can and cannot do

Be honest with yourself about this. A watermark deters casual reuse: it stops the screenshot-and-repost crowd and reminds honest people where the image came from. It does not guarantee protection. A corner mark can be cropped, and a determined editor can clone or paint a watermark out, especially over flat backgrounds. Tiling and center placement raise the effort, but nothing makes an image truly theft-proof.

Treat watermarking as a deterrent and a branding tool, not a lock. For anything sensitive, pair it with low-resolution previews and keep the full-size originals off the public web.

Image Resizer - shrink an image to web size before or after watermarking.
Image Compressor - cut file size so marked previews load fast.
EXIF Remover - strip location and camera metadata before you publish.

Mark it visibly, keep the original safe, and the casual thieves move on.
