How the watermark is made
Each picture is drawn on a canvas at its full size, and the watermark is drawn on top. Its size and the space around it are measured from the picture’s shorter side, so the mark looks the same on every picture in a batch. The edge margin is 4% of that side.
“See-through” is the watermark’s opacity. The soft shadow is a dark glow behind light colors and a light glow behind dark ones, which keeps the mark readable on busy pictures. A tiled pattern is turned by the angle and repeated across the whole picture, so cropping can’t remove it.
Files are saved at 92% quality for JPG and WebP. The new file holds only the pixels: location, camera and date details are not copied. Very large pictures (over 8192 pixels on a side) are shrunk to 8192 so every browser can draw them.

- Drop in one picture or a whole batch, or paste one. Two samples show what it does until you do.
- Type your watermark text or add your logo, then pick where it goes: a corner, the middle, or tiled across the whole picture. Change the size, see-through amount, color, font and angle, and the big preview updates as you go.
- Download the picture you are looking at, or all of them at once as a ZIP. Every picture gets the same watermark, scaled to its size.
Questions
Are my pictures uploaded anywhere?
No. The watermark is drawn in your browser with a canvas. Your pictures and your logo never leave your computer.
Which watermark is hardest to remove?
A tiled watermark across the whole picture, at an angle. A small logo in a corner looks neater, but anyone can crop it off in a few seconds. For screenshots of unreleased work or client previews, use tiled.
How see-through should a watermark be?
Between 20% and 40% works for most pictures: people can still see the work, and the mark is still clear. Go higher for a corner logo, lower for a tiled pattern.
Can I add my logo instead of text?
Yes. Pick “Logo” and add a PNG or SVG, ideally with a see-through background. Switch on “Paint it in the color” to make a dark logo white, so it shows on dark pictures.
Does the watermark stay the same size on small and big pictures?
It scales with each picture, so it looks the same on a phone screenshot and on a 4K photo.
Does it keep the photo’s location and camera details?
No. The new file is made from the pixels only, so location, camera and date details are left out.
Which file type do I get?
The same type you dropped in (JPG stays JPG, PNG stays PNG), unless you pick JPG or PNG under “File type”. JPG is smaller for photos; PNG keeps sharp edges on screenshots and text.
