Merge Images Online is a free tool that combines multiple photos into a single image composition. Join images horizontally for panoramic views or side-by-side comparisons, merge vertically for timeline sequences, or arrange in a customizable grid layout for photo collages. The online image merger processes JPG, PNG, and WebP formats while preserving image quality.
Upload two or more images to start combining photos. Select your preferred layout - horizontal for side-by-side merging, vertical for stacking images, or grid for multi-photo collages. Adjust spacing between images to control separation and visual flow. Download your merged image in high-resolution PNG for lossless quality, or choose WebP/JPG for smaller file sizes optimized for social media and web use.
Horizontal merge joins images side-by-side, perfect for before-after photos, product comparisons, or panoramic landscapes. Vertical merge stacks photos top-to-bottom, ideal for sequential storytelling, step-by-step tutorials, or timeline visualizations. Grid layout arranges multiple images in rows and columns - create Instagram collages, mood boards, or portfolio showcases with 2-6 column configurations.
Use horizontal image merge for real estate listings showing multiple room angles, product photography with different color variations, or scientific documentation requiring side-by-side specimen comparisons. Vertical merge works for mobile-optimized social media posts, infographic assembly, or comic strip creation. Grid merge excels at wedding photo collages, travel memory collections, business portfolio presentations, or any project requiring organized multi-image display.
Control spacing between merged images from 0-100 pixels to create tight seamless joins or intentional visual separation with breathing room. Grid mode supports 1-6 columns with automatic row wrapping for flexible composition. All merge modes maintain original image aspect ratios to prevent distortion. Export merged compositions up to 4096px width/height in PNG format for print-ready quality or compressed WebP for web optimization with 30-50% smaller file sizes.
