Two photos, one image
Merging two photos is the quickest way to make a before-and-after, a this-or-that, or a simple diptych. Drop both photos in, choose side by side for a horizontal pair or stacked for a vertical one, and they line up at a matching size automatically.
Add a gap so the two photos read as separate, or close it for a seamless join. A border, rounded corners, and a background colour are all one slider away — and you can export with a transparent background if you choose PNG or WebP.
How to merge two photos
- Add both photos. Drop the two images onto the tool, paste, or pick files.
- Choose the arrangement. Side by side for a horizontal pair, or stacked for a vertical one.
- Set the spacing. Adjust the gap, border, corners, and background colour.
- Download. Pick a format and size, then save the merged photo.
Before-and-after tip
For a before-and-after, side by side reads most clearly. Add a small gap and a thin border so the two halves are obviously separate, and keep both photos the same size with the Fill mode.
2枚の写真の組（ディプティク）: セルの並べ方
ちょうど2枚の写真のとき、行は同じ高さで横に並べ、積み重ねは同じ幅で上下に置きます。いずれにせよ自動的に同じサイズで揃います。すき間を閉じれば継ぎ目なくつながり、開けば2つの半分が別々に読み取られます。
このレイアウトが向いていること
- ビフォー・アフター、どちらか、またはシンプルな2面のディプティク
- 関連する2枚を組み合わせる — 横に並べた広いシーン、または積み重ねた縦長の内容
- 横と縦を切り替えてどちらが読みやすいか確かめられる、手早い比較
実用的なヒント
ビフォー・アフターには横並びが最も分かりやすいです。小さなすき間と細い枠線を足して2つの半分を明確に分け、「塗りつぶし」モードで両方の写真を同じサイズに保ちましょう。

よくある質問
Can I merge two photos of different sizes?
Yes. The tool scales both to a matching size. Use Fill to crop them to identical dimensions, or Fit to keep each fully visible.
Side by side or stacked — which should I pick?
Side by side suits before-and-after and wide scenes; stacked suits tall content or a step sequence. You can switch instantly and compare.
Can I add a gap between the two photos?
Yes. The gap slider controls the spacing, and you can add a border and rounded corners too.
