How it works

Upload your main photo

Upload the base photo — the scene you want the combined result to be set in. This is the background image. JPG, PNG, WebP up to 7MB.
Add a reference photo

Upload the second photo containing the person or element you want to blend in. The AI will extract the relevant subject from this reference image.

Tip: Make sure the person or object in the reference photo is clearly visible and well-lit for best extraction results.

Copy one of these to get started:

Add missing person to group photo Add the person from the reference photo into the group, standing on the right side. Match the lighting and make it look natural.
Try This →

Combine two portraits into one scene Combine both photos into one image with both people standing side by side, matching the background and lighting from the main photo.
Try This →

Place product into lifestyle scene Place the product from the reference photo onto the table in the main photo. Add natural shadow and match the room lighting.
Try This →

Create double exposure effect Blend the portrait with the nature scene to create an artistic double exposure effect. Make the landscape visible through the person's silhouette.
Try This →

2 more prompts

Swap background behind subject Take the person from the reference photo and place them into the beach scene. Match perspective and add a natural shadow on the sand.
Try This →

Combine pet and owner photos Add the dog from the reference photo next to the person in the main photo. Match the scale so the dog looks the right size, and add a shadow.
Try This →
Describe how to combine them

Tell the AI exactly how to blend the photos: where to place the extracted subject, how to match lighting, and any adjustments needed. Be specific about position and scale.

Tip: Mention lighting and perspective: 'place them on the right, match the outdoor lighting' gives much better results than just 'add them.'

If something looks off

Blended person looks pasted on, not natural

Why: The AI didn't match the lighting or color temperature between the two source photos.

Try: Match the lighting and color temperature of the added person to the main photo. Make the blend seamless.

Try This →

Tip: Adding 'match the warm/cool lighting' to your initial prompt prevents this issue upfront.

Person is the wrong size relative to the scene

Why: The AI couldn't determine the correct scale from the reference photo's perspective.

Try: Resize the added person to match the scale of the other people in the photo. They should be about the same height.

Try This →

Tip: Describe the expected size: 'same height as the person next to them' gives the AI a clear reference point.

Missing shadow under the blended subject

Why: The AI removed the original background but didn't generate a new shadow for the new scene.

Try: Add a natural shadow under the added person that matches the shadow direction in the main photo.

Try This →

Tip: Always mention shadows in your initial prompt to avoid a second edit.

Edge artifacts or visible outline around blended subject

Why: The extraction from the reference photo left some edge pixels from the original background.

Try: Clean up the edges around the added person so they blend seamlessly into the background.

Try This →

Tip: Reference photos with high contrast between subject and background give the cleanest extractions.

Quick answers

Can EditThisPic put photos side by side?

EditThisPic is built for seamless blending (extracting elements and merging them), not side-by-side layouts. For side-by-side, use Canva or PineTools - they're free and designed specifically for collages. EditThisPic would be overkill for simple layouts.

What's the best free tool for photo collages?

For collages and side-by-side layouts: Canva (best templates), PineTools (simplest), or your phone's built-in Photos app. For seamless blending where you extract a person from one photo and merge them into another: EditThisPic.

I want to add someone to a photo - which is that?

That's seamless blending, not side-by-side. You want EditThisPic. Upload your group photo, add a reference photo of the person, and describe where to place them. The AI extracts them and blends them in naturally.

I want a before/after comparison - which is that?

Before/after comparisons are side-by-side layouts. Use Canva or PineTools to place the two photos next to each other with a clear divider. They have templates specifically for this.

What if I'm not sure which I need?

Ask yourself: do you want to see both complete photos at once (side-by-side) or do you want elements from one photo inserted into another so it looks like one scene (blending)? The first is collage territory, the second is EditThisPic territory.
