How to Combine Images with Tancky AI

Updated

Tancky AI's image combiner merges 2 to 4 photos into one scene by analyzing subjects, lighting, and spatial depth across your references, then synthesizing a new composition with matched perspective and shadows. You can use it when you want people from separate portraits placed into a single group shot, product photos staged against a new backdrop, or furniture images placed into a room. The workflow is upload, describe, generate, download — and the page states results come with full commercial rights.

What you need before starting

  • 2 to 4 source images
  • JPG, PNG, or WebP format
  • Up to 16 MB per image
  • Clear photos with good lighting and balanced resolution

The upload area shows a counter of 0 / 4, so the tool accepts a maximum of four images per generation.

Step-by-step: combining images

Step 1 — Upload your source images

Drag or upload 2 to 4 pictures into the upload area. The interface accepts JPG, PNG, and WebP, with a limit of 16 MB each. For the cleanest merge, pick photos where the subject is clearly lit and not heavily cropped.

Step 2 — Describe your composition (optional)

The prompt field is optional and holds up to 4096 characters. Use it to describe how your subjects should interact — positioning, depth, and lighting. You can type @ to reference a specific uploaded image, which helps when you want to say which photo a subject or element should come from.

If you skip the prompt, the tool still generates a result, but you give up control over how subjects are arranged and lit.

Step 3 — Choose an aspect ratio and generate

Select your target aspect ratio, then click Generate. The page lists preset options including:

  • Group portrait
  • Portrait background
  • Furniture staging
  • Auto

The combiner synthesizes the scene in seconds. The page describes the output as harmonizing perspective, shadows, and edge contours so elements look captured in a single photograph rather than pasted into frames.

Step 4 — Review and download

Check fine details in the result — contact shadows, edge blending, and whether lighting direction matches across subjects. When it looks right, download the high-resolution output. According to the page, downloads come with full commercial rights.

How to verify the result worked

A successful merge should show:

  • Consistent light direction across all subjects
  • Contact shadows where subjects meet the ground or each other
  • No visible cutout edges or halos around subjects
  • Matching perspective — subjects at similar depths should appear at similar scale

If any of these are off, regenerate with a more specific prompt naming the problem area, or swap in a source photo with cleaner lighting.

Common sticking points

  • Too many images. The limit is 4. If you need more subjects, generate in stages and combine the outputs.
  • File too large. Anything over 16 MB per image won't upload — resize first.
  • Vague prompts. "Make it look good" gives the model little to align perspective and shadows. Name positions, depth, and light direction instead.
  • Mismatched source lighting. Photos shot under very different color temperatures are harder to fuse convincingly; starting with similar lighting reduces cleanup.
  • Unsupported formats. Only JPG, PNG, and WebP are accepted.

What you can build with it

The page highlights several use cases: merging separate portraits into couple, family, or wedding photos; creating e-commerce backdrops; and staging furniture in rooms. Related tools on the same site include an AI Couple Photo Maker, AI Family Photo Generator, AI Wedding Photo Generator, AI Background Remover, and AI Image Upscaler — useful if you need to clean up a source image before combining it.
