There are two ways to combine two photos into one: put them side by side — free, instant, and both photos stay exactly as they are — or merge them with AI into a single new photo that looks like it was taken in one shot, with matched lighting and perspective. This guide walks through both methods step by step and shows you when to pick each one. If you want to skip ahead, you can combine two images with AI right away and follow along with your own photos.
Method 1: Put Two Photos Side by Side (Free and Instant)
The simplest way to combine two photos into one image is to place them next to each other:
- Open the free side-by-side tool and select the Side by Side tab.
- Add your two photos — JPG, PNG, or WebP.
- Choose Horizontal (left and right) or Vertical (top and bottom).
- Set the spacing and background color, then tap Download PNG.
Combine Photos Side by Side — Free
This method is free, needs no sign-up, adds no watermark, and processes everything locally in your browser — your photos are never uploaded. It is the right choice when you want both photos visible in full, such as before-and-after comparisons, product comparisons, or a simple two-photo collage. For a full walkthrough including iPhone and Android methods, see how to put two pictures side by side.
Method 2: Merge Two Photos into One with AI
Side by side keeps the two photos separate. An AI image combiner does something different: it blends the subjects from both photos into one new, natural-looking image — matching lighting, shadows, skin tones, and perspective so the result looks like a single photograph.
This is the method for things like:
- A couple photo made from two solo photos
- Adding a missing family member to a group photo
- Placing a product photo into a real-life scene
- Putting a person into a travel destination they never visited
- A seamless before-and-after transition image
Here is how it works:
- Open the AI image combiner.
- Upload your two photos (up to 5 MB each).
- Describe the result you want in your own words — the scene, the pose, the mood. (Prefer ready-made presets like Couple Photo or Virtual Try-On? They live in the homepage tool.)
- Tap Generate. The AI creates your merged photo in about 10–60 seconds.
- Download the result. If it is not quite right, tweak your description and generate again.
Writing a good prompt makes the difference. Instead of "merge these two people," describe the scene you want: "Combine the two people into one natural couple photo, standing close together outdoors at golden hour, with matched lighting and skin tones." The more specific you are about the setting, pose, and mood, the better the result.
What about cost? The side-by-side stitcher is completely free — no payment, no credit card, and no hidden fees. AI merging starts with free trial credits for new accounts, then paid plans and credit packs when you need more.
Side by Side vs AI Merge: Which Should You Use?
| Side by side | AI merge | |
|---|---|---|
| Result | One image, both photos intact | One brand-new photo, subjects blended together |
| Time | Under 1 minute | 10–60 seconds per generation |
| Cost | Free | Free trial credits, then paid plans |
| Sign-up | Not required | Free account required |
| Best for | Before/after, comparisons, collages | Couple photos, group photos, product-in-scene, creative edits |
If you are showing a transformation or comparing two things, side by side is the answer. If you want two people or two elements to appear together in one scene, the AI merge is the answer.
Combining Photos on iPhone and Android
Both methods work on your phone:
- Side by side works in any mobile browser with no installation — open the stitcher in Safari or Chrome, add your photos, and download the PNG. See the iPhone and Android walkthrough for the details.
- AI merge works the same way: open the AI combiner on your phone, upload two photos from your camera roll, describe the result, and generate. No app download needed.
