Add Watermark to Photos Online
Add watermark and logo to image online free. Overlay one image over another and adjust opacity, size and position manually with sliders in real time. Perfect for logos, watermarks and digital tracing. No registration.
With this tool, you can place an image over another image directly in your browser. You can make the overlay semi-transparent, which is very useful when you want to add watermark to photos, create digital tracing, or place a logo on an image. You can move the overlay in real time, adjust its size, and use the opacity slider to control transparency. The right side of the slider is fully opaque (100%), while the left side is fully transparent (0%). For watermarks, the best transparency is usually between 10% and 40%.
Our Reduce Image Opacity Online Free Tool makes a single image transparent, while this tool lets you place that image directly over another photo so you can see immediately how it looks and adjust its opacity in real time without installing any software.
- Upload your background image.
- Upload the image you want to place on top.
- Drag the overlay to position it, adjust size and opacity.
- Download the final combined image in the same shape and size as your background image, even when working with very large files. Saving very large images may take a few extra seconds.
Perfect for artists, photographers, designers, bloggers and online sellers who need to add watermark to images, overlay logos on photos, or combine images online. Artists can set a reference photo to about 30% opacity and place it over their drawing to quickly spot proportion mistakes, working like a digital lightbox.
