Combine multiple images into a single image. Choose from horizontal (side by side), vertical (stacked), or grid layouts. Adjust gaps between images, select a resize strategy, and download the merged result. Upload as many images as you need, everything is processed in your browser with no server uploads.

Click the upload area or drag multiple images to add them. Reorder images using the up/down buttons. Choose a layout mode: Horizontal (side by side), Vertical (stacked top to bottom), or Grid (2-column arrangement). Select a resize strategy: 'Fit to smallest' scales all images to match the smallest dimension, 'Fit to largest' scales to the largest, or 'Keep original' preserves each image's size. Adjust the gap between images (0–50px) and set a background color for gaps if desired. Click 'Merge Images' to combine, preview the result, and download.
Image merging is commonly used for: creating before-and-after comparison images, building product collages for e-commerce, combining screenshots into a single reference image, creating step-by-step visual tutorials and guides, assembling panoramic views from overlapping photos, making social media collages for Instagram and Pinterest, building image sprites for web development, joining scanned document pages into a single image, and creating side-by-side design comparisons for client reviews.
This tool calculates the total canvas dimensions based on the selected layout, image sizes, resize strategy, and gap settings. For horizontal layouts, canvas width is the sum of all image widths plus gaps, and height is the maximum image height. For vertical, it's the reverse. For grid layouts, a 2-column arrangement is used. The resize strategy determines how images are scaled: 'smallest' ensures uniform width or height by scaling down larger images, 'largest' scales up smaller images, and 'original' uses native dimensions. All images are drawn onto a single Canvas at their calculated positions using drawImage() with scaling parameters.
There is no hard limit - you can combine as many images as your browser's memory allows. However, for best performance, we recommend combining fewer than 20 images at a time, especially with large high-resolution photos.
Yes. Use the up/down arrow buttons next to each image to change its position in the sequence. The order determines how images are arranged in the merged result from left to right (horizontal) or top to bottom (vertical).
Choose a resize strategy: 'Fit to smallest' scales everything down to match the smallest image (no stretching), 'Fit to largest' scales up to match the largest (may reduce quality), or 'Keep original' preserves each image's native size (may create uneven edges).
