Are my images uploaded anywhere?

No — the watermark is composited onto a canvas in your browser, so both the photo and your logo stay on your device.

Can I tile the watermark across the whole image?

Yes — enable "Tile across the whole image" to repeat the text or logo in a rotated grid, which is harder to crop out than a single mark.

What format should I download?

PNG keeps full quality and transparency; JPG produces smaller files for photos and lets you trade quality for size.

Does the output keep the original resolution?

Yes — the watermark is drawn at the image’s native pixel dimensions, so the exported file is the same size as the original.

Image Watermark

Protect and brand your images by overlaying custom text or a logo, with full control over opacity, position, rotation, margin, and tiling. Everything runs on a local canvas — your images and logo never leave your browser.

How to use Image Watermark

Upload the image you want to watermark.
Choose Text or Logo, then set the content (your text or a transparent PNG logo) and its size.
Adjust opacity, position, rotation, and optional tiling — then download as PNG or JPG.
