Watermark Image

Why Watermark Images?

Watermarking protects your intellectual property and establishes brand identity. Whether you are a photographer, designer, or content creator, adding a visible watermark discourages unauthorised use while still showcasing your work. Our tool provides a live preview in the browser and uses Sharp on the server for crisp, high-quality watermark rendering.

Features

• Custom text — type any watermark text, from brand names to copyright notices.
• Adjustable font size — scale from subtle to prominent.
• Opacity control — dial in transparency from 5 % to 100 %.
• Colour picker — match your brand colour or choose white/black for contrast.
• Four positions — center, bottom-right, bottom-left, or tile across the entire image.
• Live preview — see the watermark update in real time before downloading.

How It Works

A live preview shows your watermark settings in real time. When you download, Sharp composites an SVG text overlay onto the image on the server with your chosen font size, colour, and opacity. In “tile” mode, the text is repeated in a grid pattern across the full image. The final result is exported as a high-quality PNG.

Best Practices

• Use 20–40 % opacity so the watermark is visible but does not obscure the image.
• Place watermarks on important areas of the image to prevent easy cropping.
• Tile mode is the most difficult to remove and works well for stock photography.
• Match the watermark colour to the image's dominant tones for a professional look.
