What kind of watermark does this add?

This tool overlays a logo image onto your photos. If you want a text watermark instead, use our text watermark tool; for videos, use the video watermark tool.

What logo format should I use?

A transparent PNG works best because the background stays invisible. JPG and WebP logos also work but will include their background.

Are my photos uploaded anywhere?

No. The logo is composited onto your photos entirely in your browser, so nothing leaves your device.

Can I watermark many photos at once?

Yes. Add a batch of images and apply the same logo, position, size, and opacity to all of them in one go.

Can I control where the logo appears?

Yes. You can place the logo in any corner or the center and adjust its size and transparency to suit each photo.

What output formats can I save to?

You can export your watermarked images as JPG, PNG, or WebP depending on your needs.

Yes. We add no watermark of our own, and there are no sign-ups or file-size limits beyond what your device can handle.

Brand your photos with your own logo

Protect and brand your images by placing your own logo on top of them. Upload a transparent PNG logo, choose where it sits, and fine-tune its size and opacity for a subtle or bold look. Everything is composited on an HTML canvas inside your browser, so your photos and logo are processed on your own device and never sent to a server. Apply the same logo across a whole batch and download the results in seconds.

Your images stay private

All watermarking happens directly in your browser. Your photos and your logo are composited together on a canvas on your own device, and are never uploaded to any server. We collect only anonymous, aggregated usage statistics (such as how often the tool is used) to improve it — never your images, logo, filenames, or any personal data.

Verify it yourself: Open your browser DevTools → Network tab and run the tool: no request ever carries your file. Everything happens on your device.
