How it works

How to merge images online

Merging pictures into one file takes three steps — no software to install, no account to create.

1

Add your images

Drag and drop photos onto the image merger, click to browse, or paste a screenshot straight from your clipboard.

2

Choose a layout

Combine images horizontally, stack them vertically, arrange a photo grid, or place them freely on a canvas. Adjust spacing, background, and rounded corners live.

3

Download one image

Export the merged result as PNG, JPG, or WebP at full resolution. The file is generated instantly on your device.

Four ways to merge

One image merger, every layout you need

Merge images horizontally

Merge images in a row, one next to the other — perfect for before/after comparisons, product shots, and combining screenshots into one wide image. Heights are matched automatically so the row lines up cleanly.

Merge images horizontally →

Merge images vertically

Stack photos on top of each other into one tall image — ideal for stitching long chat screenshots, receipts, step-by-step instructions, or full-page captures into a single scrollable picture.

Make a photo grid

Combine multiple photos into a tidy grid collage — great for mood boards, product galleries, social posts, and photo dumps. Choose the number of columns and let the tool do the math.

Freestyle collage canvas

Need full control? Drop images on a blank canvas and drag them anywhere, resize with a scroll or a corner handle, and layer them to build a custom collage — then export it all as one image.

Open the canvas →

FAQ

Frequently asked questions

How can I merge two pictures together?
Drag both pictures onto the tool above (or click to browse, or paste with Ctrl+V). Choose Horizontal to merge images in a row or Vertical to stack them, adjust the spacing and background to taste, then hit Download — you get one merged image file.
Is this image merger really free?
Yes — completely free. No hidden fees, no watermark on your images, no signup, no limits. The tool runs in your browser, so there are no server costs to pass on to you.
Are my pictures safe? Are they uploaded anywhere?
Your pictures are never uploaded to a server. Everything is processed directly in your browser with the HTML5 Canvas API, so your images stay private, on your own machine — safe for personal photos, ID documents, and work screenshots.
Will I lose quality when merging images?
No. Merging happens at the full resolution of your originals. Export as PNG to keep lossless quality, or pick JPG/WebP and use the quality slider when you want a smaller file.
How many pictures can I merge at once?
Up to 20 images per merge — in a row, a column, a grid, or freely arranged on the canvas.
What layouts can I choose for merging images?
Four layouts: Horizontal (side by side), Vertical (stacked), Grid (equal cells with your choice of columns), and Freestyle — a blank canvas where you drag, resize, and layer images with full control.
What types of image files can I use?
You can add PNG, JPG/JPEG, WebP, GIF, AVIF, and BMP files, and export the merged result as PNG, JPG, or WebP.
Do I need to install any software?
No installation, no download, no account. The image merger runs entirely in your web browser — open the page and start merging right away.
