Combine Images

Combine images into one picture

Need a before-and-after comparison, a photo strip or a quick contact sheet? This tool will combine images into a single file in seconds. Add your pictures, choose how they are arranged, and download the merged result as PNG, JPG or WebP.

Everything runs on your device. The photos are decoded and drawn onto a canvas in your browser, so they are never uploaded. It also reads HEIC, TIFF and BMP files, which most online mergers cannot.

Layout options

Side by side places the images in one row, stacked puts them in a single column, and grid lays them out in the number of columns you choose. With "match sizes" turned on, images in a row are scaled to the same height (or to the same width when stacked), so there are no ragged edges. Turn it off to keep every image at its original size, centered within its row.

Gap, background and format

Add a gap in pixels to separate the pictures and pick any background color for the spaces between them. Save as PNG for lossless output, JPG for the smallest photo files, or WebP for modern websites. Use the arrow buttons to reorder the images, remove the ones you do not need, and watch the live preview and final dimensions update as you go.

The merged image is limited to about 16.7 megapixels, the largest canvas that every major browser, including Safari on iPhone and iPad, can create reliably. If your photos add up to more, the result is scaled down proportionally and the summary shows the final pixel size, so the download never comes out blank. Browsers that cannot encode WebP save PNG instead and tell you. For a classic grid collage, try the photo collage maker; to compare two versions of a picture with a slider, use image compare; and to cut one picture into tiles, use the image splitter.
