Image Watermark Tool: An image watermark tool adds text or a logo over your images to protect and brand them. Set the text, font, opacity and position, preview live, and download the watermarked image — all in your browser with no upload.
Frequently Asked Questions
How do I add a watermark to an image?
Upload the image, type your watermark text or add a logo, adjust its position, size and opacity, then download the result. The watermark is baked into the exported image.
What opacity should a watermark use?
A watermark around 30–50% opacity is visible enough to deter reuse while remaining subtle enough not to ruin the image. Tiled or corner placement is common for photos.
Can I use my logo as a watermark?
Yes. Upload a transparent PNG logo and position it over the image. Lowering its opacity helps it blend without dominating the photo.
Are my images uploaded when watermarking?
No. Watermarking runs entirely in your browser on a canvas, so your original and watermarked images stay on your device.
