Phone Mockup Generator

When you generate a mockup, the tool doesn't just paste your screenshot blindly on top of a phone picture.

If it did, the sharp, square corners of your screenshot would stick out past the rounded corners of the phone bezel, and you'd be covering up the phone's camera notch or dynamic island.

To make the mockup look perfectly realistic without complex manual masking, we use the HTML5 Canvas globalCompositeOperation property, specifically setting it to destination-over.

• Step 1: We first draw the Phone Frame. The frame is a transparent PNG where the "screen" area is completely transparent, but the bezel, corners, and notch are solid.
• Step 2: We draw your screenshot. But because we set the composite operation to destination-over, your screenshot is mathematically forced to render underneath the existing phone frame.

Because your screenshot renders underneath, the rounded corners and the "notch" of the phone frame naturally overlap your image.

This creates a perfect, clipping-free mockup without requiring any complex polygon intersection math to trim the corners of your screenshot.
