Simple, Powerful and Intelligent

Aquamark automagically watermarks your images. Simply drag and drop as many images as you like, and leave the rest to Aquamark!

Images come in all shapes, sizes and colors. No matter how many images you drop into Aquamark, it treats each of them intelligently to configure the watermarking process to produce consistent and beautiful results.

If you want to focus on creating content, and not on how to watermark it, Aquamark is perfect for you.

On the other hand, even if you are a graphic designer with tons of complex image editing software at your disposal, I believe you will appreciate how easily you can watermark images with Aquamark.

Aquamark supports common bitmap file formats (JPEG/JPG, PNG, BMP, TIFF).


In Automatic Mode, Aquamark determines optimal values for:

--- How Best to Position the Watermark:
In order to protect your image, we have to ensure someone cannot simply crop it out.

--- How Best to Draw the Watermark:
Your image is beautiful, and Aquamark knows that! It doesn't want to change it any more than strictly necessary to imprint a legible watermark onto it. It dynamically adjusts parameters to ensure that it is your image that stands out - not the watermark on top of it.


In Manual Mode, you have more control.

When you drop any number of images, Aquamark presents them to you one by one so that you can adjust the position, size, and angle as you like by simply dragging the watermark over your image. Each time you reposition the watermark, Aquamark recalculates what opacity value will make your watermark look great in its new place.

Optionally, you can set the opacity value yourself - for those times when you actually want the message to stand out.

In manual mode, you can apply as many watermarks onto a single image before moving on to the next one. Just apply, reposition, and apply again!


I originally made Aquamark for my mother. She is an artist who paints all sorts of lovely stuff, but doesn't care much for computers. The times being what they are, she decided to post some of her paintings through social media, bringing about the need for a powerful, yet easy to use watermark app.

I, on the other hand, love computers and programming.

And so, Aquamark was born... doing what I love, for someone I love.

She loved it, and I hope you will too.

Very basic, which is what I wanted

I was only looking for an easy, even automatic way to watermark my pictures. Not too much control in manual mode, automatic is great (but of course you can’t really change much) I like that it’s drag, drop and click. I don’t use special effects or features, so this is fine with me.
