About this tool
Upload an image and add a text watermark with live preview. You can control the text content, font size, color, opacity, and position. Choose from fixed positions like bottom-right or center, or tile the watermark diagonally across the entire image for stronger protection.
The watermark includes a subtle shadow effect for readability against varied backgrounds. Everything runs in your browser using the Canvas API, so your images stay private. Download the result as a PNG when you are happy with the placement.
Frequently asked questions
What watermark types are supported?
Text watermarks with customizable font size, color, and opacity. You can place the watermark in 7 fixed positions (corners, edges, center) or tile it across the entire image.
Can I adjust the watermark opacity?
Yes. The opacity slider goes from 5% (nearly invisible) to 100% (fully opaque). A value around 30-50% works well for most watermarks.
What output format do I get?
The watermarked image is exported as PNG. Canvas-based processing means it works with any input format your browser can display (JPEG, PNG, WebP, etc.).
