Combine images into one

The tool lines up your images in the order you choose:

• Side by side: all images are scaled to the same height (the height of the shortest image), then placed next to each other from left to right.
• Stacked vertically: all images are scaled to the same width (the narrowest image), then placed one under another from top to bottom.

Because the images are matched in height or width, nothing is cropped and nothing is stretched out of proportion. The optional spacing (0–60 px) adds a white gap between images. The result is saved as a high-quality JPG named combined-image.jpg.

Everything happens in your browser, and your photos are never uploaded.

To add labels such as "Before" and "After", combine the images first, then use Add text to image.

• Use similar shapes. Images with the same aspect ratio line up neatly. If one is very tall and another very wide, the result has uneven sizes. Crop them first with Crop image.
• Mind the resolution. All images are scaled to the smallest height or width, so one tiny image makes the whole result small. Use photos of similar size.
• Spacing: 0 px gives a seamless strip; 10–20 px gives a clear separation, like a photo strip.
• Order matters. Use the up and down arrows next to each file to reorder before combining. Remove a file with its X button.

This tool makes simple strips: a row or a column. For grids, featured layouts with one large photo, rounded corners or custom background colors, use the collage maker. For an animation that shows the images one after another, use the GIF maker.

Need the combined image smaller for email or an upload form? Run it through Compress image afterward. To stack scanned pages into a document instead, a PDF is usually the better format.

Example: you have a before photo at 3000 × 4000 px and an after photo at 1500 × 2000 px. Side by side, both are scaled to 2000 px tall, so the combined image is 3000 px wide plus spacing. The larger photo loses resolution, but both appear at the same size, which is what a fair comparison needs.

You can combine JPG, PNG, WebP, HEIC (iPhone), AVIF, GIF, BMP, TIFF and SVG files, even mixed together. The output is always a JPG, so transparent areas in PNG images appear white. There is no fixed limit on the number of images, but very long strips with many large photos may take a moment to process on older devices.
