Frequently Asked Questions (FAQ)
真实解答您最关心的隐私安全、收费模式、官方审核通过率与导出细节。
What is Contact Shadow (Ambient Occlusion / AO)?
Contact shadow is the intense, tight shadow formed directly beneath where an object meets a surface. It is essential for eliminating the 'floating' effect and giving objects realistic physical gravity.
Can I use un-clipped photos with backgrounds?
Yes! Click 'Upload & Auto AI Cutout' to let our high-precision model remove the background automatically and render 3D lighting immediately.
Does the transparent PNG download keep the shadow?
Yes! Selecting 'Transparent (PNG)' exports a true alpha-channel PNG with semi-transparent drop shadows intact, ready to overlay anywhere.
Are my images uploaded to external servers?
Physics shadow synthesis, directional projection, and blurring run 100% locally in your browser memory for total privacy.
