Overlay one image on top of another with customizable opacity and positioning
Upload your base image and overlay image
Supports JPG, PNG, and WebP formats
Overlaying images is at the core of a huge range of visual effects: adding a watermark, creating a double-exposure effect, compositing a logo onto a background, building a product mockup, or simply combining two images with transparency. This image overlay tool online free 2026 gives you precise control over how two images combine — position, scale, opacity, and blend modes — all in a browser-based editor that requires no software installation and sends nothing to any server.
The blend mode selector is where the creative possibilities expand significantly. Normal blend just places one image on top of the other based on opacity. Multiply darkens where images overlap. Screen lightens. Overlay combines both. The blend mode image overlay tool free online includes Multiply, Screen, Overlay, Soft Light, Hard Light, Difference, and more — the full set of blend modes that Photoshop users are familiar with, available in a free browser tool.
The overlay logo on photo online free 2026 use is straightforward — upload a background photo, upload a PNG logo with transparent background, position it where you want it on the photo, adjust size and opacity, and download. This is how product photographers add branding to lifestyle shots without opening Photoshop.
Double exposure effects — placing a portrait over a landscape or abstract background with transparency — create striking artistic images. The double exposure effect online free 2026 is achievable with Screen or Multiply blend mode at reduced opacity, creating the characteristic transparent overlap look. Experiment with different blend modes to see which gives the effect you're aiming for.
Not necessarily — it depends on the effect you want. PNG images with transparent backgrounds overlay cleanly onto the base image, showing only the non-transparent parts. Images without transparency overlay their entire rectangular frame. For most overlay uses (adding logos, watermarks, decorative elements), PNG with transparency gives the cleanest result.
If either image has transparency, the output is PNG to preserve transparency. If both images are fully opaque JPGs, the output can be JPG for smaller file size. You can select the output format in the download options based on your use case.
