Batch Watermark Images
Choose up to 20 images and stamp them all with the same watermark — your text, your logo, or both — in one corner or tiled across the whole photo. Each finished file gets its own Download button — or tap Download all as ZIP to save the whole batch at once. Everything runs in your browser. No upload, no signup, and we never add an ImageTool.us stamp: only your watermark goes on the photo.
Output is JPG, so transparent areas of a PNG become white. The watermark is baked into the image — it cannot be removed by simply downloading it again, so keep your original unwatermarked photos safe.

Nothing is downloaded automatically: tap a Download button, or Download all as ZIP, to save. The ZIP stores the finished files as they are, without recompressing them. No vendor stamp is added at any step.
How batch watermarking works
- Choose up to 20 images.
- Pick text, logo, or both, then a style, position, color, opacity and size.
- Click Watermark batch. Each finished file gets its own Download button — or tap Download all as ZIP to save the whole batch at once. Nothing is downloaded automatically.
Which style should you pick?
A single corner watermark is the least intrusive choice for product photos and listings: bottom right is the usual spot, and medium size at 50% opacity stays readable without hiding the product. A tiled watermark repeats diagonally across the whole photo, which is harder to crop out — use it for portfolio images or proofs you share before payment. A logo watermark works best when the logo has a plain background and is wider than it is tall; the logo is scaled to the share of photo width you pick, keeping its own proportions.
Frequently asked questions
Are my images uploaded?
No. All watermarking runs on your device, in your browser, and the ZIP is built on your device too.
Does ImageTool.us add its own watermark?
No. Only the text or logo you choose goes on the photo. There is no vendor stamp, and nothing is added to the ZIP.
Can I remove the watermark later?
No — once it is baked in, the only clean copy is your original. Always keep the original.
What happens to transparent PNGs?
Output is JPG, which cannot hold transparency, so transparent areas become white. If you need to keep transparency, do not use this tool for that file — keep the PNG version unwatermarked.
