Protect your photos and artwork by adding custom text watermarks. This free online watermark tool lets you control exactly how your watermark appears, including the text, position, transparency, and size. Everything processes locally in your browser, so your images are never uploaded to any server.
Upload any image and type your watermark text. Choose where to place it (center, or any corner), adjust the opacity so it is visible but not distracting, and set the font size to match your image dimensions. The preview updates in real-time as you adjust settings. When you are satisfied, download the watermarked image as a PNG file.
Set opacity between 30-50% for watermarks that are visible but do not overpower the image. Place the watermark in the center for maximum protection, or in a corner for a subtler branding approach. Use a font size proportional to your image dimensions. For large images, a font size of 48-80px works well, while smaller images may need 20-36px.
