Overlay Images Online Free

Build a Composite with Two Images

Upload a base image and a second image as an overlay. Position and resize the overlay, set its overall opacity, then apply and flatten it onto the base canvas.

Base image
Overlay image

Apply & Flatten composites the overlay onto the base. There is no edge-feathering control, and the applied images are not kept on separate layers.

🖼️
Upload Both Images
Load a base image and a second image as an overlay. Transparent areas in a PNG remain transparent.
🎚️
Position and Resize
Drag the overlay or adjust its X, Y, width, and height before applying it.
💧
Opacity and Flattening
Set one opacity value for the complete overlay, then use Apply & Flatten to composite it onto the base canvas.

How It Works

  1. Upload the base image. Choose the picture that will form the background of the composition.
  2. Add and place an overlay. Upload a second image, drag it into position or set X and Y, adjust its size, and set opacity for the whole overlay.
  3. Review, then Apply & Flatten. Applying composites the overlay onto the base canvas. The tool does not feather edges or keep separate layers.

About This Tool

Use Paste & Blend to upload a base image and a second image as an overlay. Reposition or resize the overlay, adjust its 0–100% opacity, and apply it to the base canvas. Applying flattens the result; it does not preserve separate layers or feather edges.

🖼️ Base and Overlay
Choose the background image first, then upload a second image to place over it.
↔️ Position and Size
Move the overlay or set its X, Y, width, and height in the tool controls.
🎚️ Whole-Overlay Opacity
Set a single opacity value from 0% to 100% for the complete overlay image.
🧩 Apply & Flatten
The overlay is drawn onto the base canvas when applied; it is not retained as a separate editable layer.

Paste & Blend FAQs

Can I move and resize the overlay?

Yes. Drag it on the canvas or adjust X, Y, width, and height in the controls before applying.

Does the opacity slider affect just part of the overlay?

No. One opacity value applies to the complete overlay image. Transparent pixels already present in an uploaded PNG remain transparent.

Can I feather or soften the overlay edges?

There is no edge-feathering control. Use an overlay image that already has transparent edges if that is the look you need.

Are the images kept on separate layers?

No. Apply & Flatten composites the overlay onto the base canvas rather than preserving separate editable layers.

Can I add a watermark?

Yes, upload your own logo or signature image and lower its opacity. This tool places image files; it does not create watermark text.
