How to Add a Logo Watermark to an Image

Upload your photo, then upload your logo (PNG with transparent background works best). Adjust the scale so the logo is the right size relative to your image, set the opacity, choose the position, and download. Your logo is overlaid on the image entirely in your browser — no server, no upload.

Why Use PNG Logos for Watermarks?

PNG files support alpha transparency, meaning the background of your logo is invisible — only your actual logo shape is visible when overlaid. JPG logos have a white or colored background that creates an unsightly rectangle on your image. Always export your logo as PNG for watermarking.

Logo Placement Best Practices

For brand visibility, place the logo in a corner at 15–25% scale and 60–80% opacity. For copyright protection, use Tiled mode to repeat your logo across the entire image. For portfolio use, bottom-center at 20% scale with 50% opacity creates a watermark that identifies without distracting.

Frequently Asked Questions

What image format should my logo be in? ▾
Use PNG format with a transparent background. This ensures only your logo shape is visible when overlaid, with no white or colored rectangle behind it. If your logo is JPG, you can convert it to PNG using our Convert tool first.
How big should my watermark logo be? ▾
10–25% of the image width is the typical range. Below 10% and it becomes too small to see clearly. Above 30% and it starts to overshadow the main content. Adjust using the Scale slider until it looks right on your specific image.
Can I use a QR code as a watermark? ▾
Yes! Enter your website URL in the QR Code section and click Generate. A QR code is instantly created and used as your watermark logo. Anyone who scans the watermark gets taken directly to your site — great for portfolio images.
My image file is uploaded to a server? ▾
No, never. All processing happens inside your browser using the HTML5 Canvas API. Your photo and logo are never transmitted anywhere. This tool even works offline once the page loads.
