How does the reference image workflow work?
Upload your subject photo first, then click '+ Add reference image' to upload the background scene you want. Tell the AI 'place my subject into the reference background' and it composites them together, automatically matching lighting and perspective.
Does my photo need to have a transparent background first?
No. EditThisPic works with transparent PNGs, solid color backgrounds, or existing scenes. The AI identifies your subject and composites it into the reference background automatically. Transparent or plain-background images tend to give the cleanest results.
What makes a good reference background image?
Any photo of a scene you want your subject placed into. Higher resolution helps. Scenes with clear spatial depth and consistent lighting work best. The AI handles the rest — matching lighting direction, color temperature, and perspective between subject and reference.
Can I composite a group photo into a reference background?
Yes. Upload the group photo as your subject and the desired scene as your reference image. The AI handles multiple subjects and composites everyone into the reference background together.
Will the AI match the lighting between my subject and the reference?
Yes — the AI automatically adjusts lighting direction, color temperature, and shadows to match the reference scene. For best results, choose reference images where the light direction roughly matches your subject's lighting.
Is EditThisPic's AI background adder really free?
Yes — you get 1 free edit per week, no account needed. For unlimited edits, plans start at $3.99/month.
Can I add background on my phone?
Yes. EditThisPic works in any mobile browser — iPhone, Android, tablet. Upload both your subject and reference image right from your camera roll. No app download needed.
What photo formats does the AI background adder support?
JPG, PNG, WebP, and HEIC — for both your subject photo and your reference background image.
