Foreground Background Image Comparer

This foreground and background image comparer lets you upload a background image and a foreground image directly in the browser, then quickly preview how the foreground looks over the background. You can drag the foreground, adjust scale, opacity, and blend mode, making it useful for checking cutout assets, product images, portrait composites, and design mockups.

All processing happens on the front end, so images are never uploaded to the server. While comparing, you can add the current result as a temporary snapshot on the page and delete snapshots you no longer need.
