Want to combine several photos into a single image — a neat grid for Instagram, a before-and-after, or a simple photo wall? You don't need Photoshop or an app. This guide shows how to make a photo collage in your browser and merge everything into one image, free.
Make a collage in four steps
- Open the tool. Head to the Image Merger — it shows an empty grid straight away.
- Set your grid and size. Choose how many rows and columns you want, and a canvas size (or tap a ratio like 1:1 or 4:5 for social posts).
- Fill the cells. Click any empty cell and pick a photo — it drops in and fills the cell automatically. Repeat for each cell.
- Adjust and download. Click a cell to reposition or zoom the photo inside it, set the gap, frame and background colour, then download as PNG or JPG.
Pick the right size for where it's going
- Instagram post — use a 1:1 (square) or 4:5 (portrait) canvas so it fills the feed cleanly.
- Story or Reel cover — a 9:16 tall canvas.
- Before / after — a 1×2 or 2×1 grid on a wide or tall canvas.
- Photo wall / moodboard — a larger grid like 3×3 or 4×4.
Get each photo sitting right
Because every photo lives in its own cell, the layout always stays aligned. Click a cell to select it, then drag to reposition the photo and use the zoom slider to scale it inside the frame — handy when a face or subject is off-centre. Add a gap between cells and an outer frame in any colour for a clean, bordered look, or set them to zero for a seamless grid.
Everything stays on your device
The collage is built entirely in your browser — your photos are never uploaded to a server. That makes it fast and private, and there's no sign-up or watermark on the result.
