How to Use the Image Watermark Tool
Upload any image and type your watermark text — a copyright notice, brand name, or URL. Select one of 9 positions to place the watermark, then adjust font size, color, and opacity to blend it naturally. Click Apply to preview and download the result as PNG. All processing happens in your browser; your image never leaves your device, making this tool completely private and safe for sensitive photos.
Frequently Asked Questions
Can I remove the watermark later?
No. The watermark is merged directly into the image pixels. Keep your original file so you can re-apply with different settings if needed.
Is my image uploaded to a server?
No. All processing happens in your browser using the HTML5 Canvas API. Your image never leaves your device.
What image formats are supported?
You can upload JPG, PNG, WebP, or any browser-supported format. The output is always saved as PNG.
