Can I use my logo as a watermark instead of text?

Yes, both text watermarks (with your choice of wording and font) and image watermarks using an uploaded logo or graphic are supported.

Can I control opacity so the watermark isn't too distracting?

Yes, opacity is fully adjustable, along with an optional drop shadow to help the watermark stand out against busy backgrounds without needing to be fully opaque.

Can I apply the same watermark to many photos at once?

Yes, batch watermarking applies your configured watermark (position, opacity, rotation, and all) to every uploaded image in one pass.

Where can I position the watermark?

Position is freely adjustable, whether that's a corner for a subtle brand mark or a large diagonal watermark across the center to more strongly discourage unauthorized use.

Does watermarking affect the underlying photo's quality?

The watermark is layered on top of the image; the underlying photo pixels outside the watermark are otherwise unaffected, aside from whatever output quality setting applies to the final saved format.

Is my image uploaded to a server?

No. Every operation runs locally in your browser using JavaScript and WebAssembly. Your image is never transmitted anywhere, which also means it works without an internet connection once the page has loaded.

Watermark Image

Overlay a text or image watermark with control over opacity, rotation, and shadow.

Processed entirely in your browser — your file is never uploaded anywhere.

Why watermark images with Tools Root

Protecting photos you're sharing publicly — portfolio work, product photos, stock images — from unauthorized reuse, or simply branding images consistently with a logo, is a common need for photographers, designers, and small businesses.

Full styling control, applied in batch

Position, rotation, opacity, and drop shadow are all adjustable with a live preview, and the same configuration can apply across a whole batch of images at once rather than repeating the setup photo by photo.

Common use cases

Watermarking portfolio photos before posting them publicly online, branding product photos with a company logo before listing them for sale, adding a copyright notice to stock photography, or marking preview images to discourage use before a client has paid for the final files.
