Place a readable text watermark on a photo before sharing it. You control the text, size, opacity, and position. A light fill and dark outline keep the mark visible across both bright and dark parts of the image.

How to use Add Watermark

  1. Choose the photo or graphic.
  2. Enter watermark text and adjust its size, opacity, and position.
  3. Process the image, review the preview, and download the watermarked copy.

Things worth knowing

  • A watermark discourages casual reuse but cannot prevent determined removal.
  • Keep the mark away from important faces or product details.
  • Work from an original image each time to avoid repeated lossy encoding.

Frequently asked questions

Can I add a logo watermark?

The first version supports text. Logo overlays require a second local image input and are planned separately.

Does NooCloud store the watermark text?

No. The text stays in the page and is drawn directly onto the local canvas.
