How it works
-
Drop your photos here
Drag up to 30 .jpg, .png or .webp images (50 MB each) onto the dotted area, or click to choose. You can keep adding in batches until the lot is full.
-
Build the watermark
Choose text or a .png logo; set the position on the 3×3 grid, the opacity (10 to 100%) and the size as % of the width. The first photo shows the result live.
-
Apply and download
Click "Apply the watermark" — the bar tracks photo by photo. Download one by one or everything at once as a .zip.
Frequently asked questions
Can I use my logo as the watermark?
Yes — drop a .png, ideally with a transparent background, so it sits on the photo without that white rectangle around it. The size follows the slider, as % of each photo's width.
Does the photo quality change?
JPG and WebP are re-saved at 0.92 quality — the difference is invisible to the naked eye. PNG comes out lossless. The original resolution is kept in all of them.
Where should I place the mark to protect best?
A plain corner is easy to crop out. To make it harder, use the center or a third of the image with lower opacity (20 to 40%) — it bothers viewers less and removers more.
Does white text vanish on bright photos?
The tool draws a soft shadow behind the text precisely so it holds on any background. If it still fades, raise the opacity or the size on the slider.
How many photos per batch?
30 photos up to 50 MB each — beyond that the browser would start choking. Got more? Run another batch right after; your watermark settings stay as you left them.
Are my photos uploaded to a server?
No. The watermark is drawn inside your browser, photo by photo, on your device. You can even turn off Wi-Fi after the page loads.
