Protect your images with watermarks
Adding a watermark to your photos and graphics is the simplest way to protect your intellectual property online. Whether you are a photographer, designer, content creator, or business owner, watermarking your images ensures your name or brand stays visible even when images are shared without permission.
Our tool lets you add text or logo watermarks to any image — completely free, with no uploads. All processing happens locally in your browser, so your original images stay private.
Frequently asked questions
Is my image uploaded to a server?
No. All watermarking is done using the browser Canvas API. Your images never leave your device.
What is the best watermark for photos?
For photos, a semi-transparent white text watermark at 50–70% opacity in the bottom-right corner works well. Use a brand name or website URL. For maximum protection against removal, use the repeat/tile option.
Can I use a PNG logo as a watermark?
Yes. Upload a PNG logo with a transparent background for the best result. The logo will be placed at your chosen position with the opacity you set.
Will the watermark reduce image quality?
No — the watermark is drawn directly onto a copy of your image using the Canvas API. The original image quality is fully preserved.
