The fastest way to put two pictures side by side is with a free online photo stitcher: open the tool, drag in both photos, pick horizontal or vertical, and download them as a single image — no app to install, no sign-up, and no watermark. Here is the full step-by-step method, plus how to do the same thing on iPhone and Android.
The Fastest Way: Use a Free Online Tool (No App Needed)
A browser-based photo stitcher does the whole job in under a minute and works on any device — phone, tablet, or desktop. Here is how:
- Open the free side-by-side tool and select the Side by Side tab.
- Tap Select images and pick your two photos. JPG, PNG, and WebP all work.
- Choose Horizontal to place them left and right, or Vertical to stack them top and bottom.
- Adjust the spacing between the photos and pick a background color if you want one — white, black, or any color.
- Tap Download PNG and the combined image saves to your device.

Two things worth knowing. You can add up to 6 images at once, which is handy for a before-during-after sequence or a comparison grid. And nothing is uploaded to a server — the tool processes everything locally in your browser, so your photos never leave your device.
How to Put Two Pictures Side by Side on iPhone
Apple's Photos app does not have a built-in side-by-side feature, so iPhone users have three practical options:
Option 1: The free web tool (fastest). The method above works in Safari on any iPhone. No App Store download, no account, and the result saves straight to your Photos library.
Option 2: Pages. Apple's free Pages app can place two photos next to each other on a page, which you can export as a PDF or screenshot. It works, but it takes several more steps than a dedicated tool.
Option 3: Shortcuts. The Shortcuts app has a "Combine Images" action that joins two photos side by side in two taps — but you need to build or download the shortcut first.
For most people, Option 1 wins on speed: open Safari, upload, download, done.
How to Put Two Pictures Side by Side on Android
Android has a built-in option plus the web tool:
Google Photos collage. Open Google Photos → Utilities → Collage, select your two photos, and the app places them side by side automatically. It is free and already installed on most Android phones. The catch: you get one preset layout, with limited control over spacing, borders, and background color.
Samsung Gallery. Newer Samsung phones include a basic collage mode in the Gallery app that works the same way.
The free web tool. If you want control over spacing, background color, and direction — or need a vertical stack instead of a horizontal one — use the free side-by-side stitcher. It runs in any Android browser (Chrome, Samsung Internet) and needs no installation.

Tips for Better Side-by-Side Photos
- Crop both photos to the same height. In a horizontal layout, a portrait photo next to a landscape photo leaves awkward empty space. Crop them to matching heights first so the edges align cleanly.
- Keep the lighting consistent. Two photos shot in similar light look like a set. One bright photo next to one dark photo will always look mismatched.
- Use a small gap or border. An 8–24 px gap makes the layout look intentional. Zero spacing between two unrelated photos often looks accidental.
- Match the size to where you will post it. For Instagram posts use a 4:5 portrait (1080 × 1350 px), for YouTube thumbnails 16:9 (1280 × 720 px), for Instagram Stories and TikTok 9:16 (1080 × 1920 px). Crop to those dimensions before combining.
- Before-and-after photos are a natural fit. Fitness, renovation, skincare — side by side is the standard way to show a transformation. If you want a single image with a smooth transition line instead of a hard gap, try the free before-and-after maker.
