Image Watermark Tool — Add Text Over Any Image

Upload an image and overlay custom text as a watermark, with full control over position, opacity, font size and rotation — the image never leaves your browser, so it works for photos you have not published yet without any upload step.

How to use Watermark Tool

1. Upload your image.
2. Enter your watermark text.
3. Adjust position, opacity, size and rotation.
4. Download the watermarked image.

Frequently asked questions

Is my image uploaded to a server?

No. The watermark is composited onto the image using your browser's canvas, and the file never leaves your device.

Can I add a logo instead of text?

This tool overlays text watermarks; for a logo or image-based watermark, use an image editing tool with layer support.

What opacity should I use for a watermark?

Around 30-50% is common — visible enough to deter unauthorized use, subtle enough not to obscure the image content.
