Merge multiple images into one canvas in horizontal or vertical layout.
Image Combiner merges two or more images into a single canvas with horizontal or vertical layout, adjustable gaps, and a custom background color. It is completely free, works in any modern browser, and requires no account or software download.
Image Combiner is a browser-based utility that stitches multiple images together into one unified output. Choose between horizontal (side-by-side) and vertical (stacked) arrangements, set a pixel gap between each image, and pick a background fill color for any empty space. All processing happens client-side using the HTML canvas API, so your images are never uploaded to a remote server. The final result downloads as a single PNG file ready for sharing or embedding.
Select two or more images through the file input. Pick your preferred layout direction -- horizontal or vertical -- and set the gap between images in pixels. Choose a background color to fill any spacing or size differences. Click Combine to render the merged canvas, then preview the result directly on the page. When you are happy with the output, click Download PNG to save the combined image to your device. Use the Clear button to start over with a new set of images at any time.
