Compare two photos, instantly. From photo edits and DIY projects to plant growth records — see exactly what changed, in four powerful modes.

Four Comparison Modes

▼ Side by Side View both images at once. Perfect for progress photos.

▼ Slider Drag a slider across one image to reveal the other underneath. Smoothly check before/after photo edits.

▼ Opacity Overlay two images and adjust transparency. Great for spotting alignment shifts and subtle changes.

▼ Difference Subtract one image from the other to highlight only what's changed. Reveals details invisible to the naked eye.

• You can save the difference image to your Photos.
