Choose The Right Tool
Use horizontal merge when the output must read left-to-right, like comparisons, banners, panoramas, and before/after images.
Join photos seamlessly
Use this when the goal is a cleaner joined-photo presentation rather than a technical merge term.
Stack images top to bottom
Switch if your content should stack top-to-bottom instead of left-to-right.
Create stunning photo collages
Switch if a single row is too rigid and you need a grid or template.
Horizontal image merging combines multiple photos side by side from left to right into a single image. This creates a panoramic-style layout perfect for comparisons, before/after shots, and creating wide visual displays.
Simply upload your images to our horizontal merge tool, arrange them in your preferred order, adjust spacing if needed, then click 'Merge & Download'. The tool automatically aligns images side by side.
You can merge as many images as you need horizontally. Start with 2 images and add more using the 'Add More' button. For best visual results, we recommend 2-6 images to maintain clarity.
Images maintain their original aspect ratios. When merging horizontally, images are aligned by their tops and the final height matches the tallest image. Very large combined images may be scaled to fit within reasonable dimensions.
Yes! Use the spacing slider to add customizable gaps between your images. You can also choose a background color that shows through the spacing for a polished look.
Horizontal merging is ideal for before/after comparisons, product showcases, panoramic views, step-by-step tutorials, timeline displays, and creating social media banners or website headers.
Yes, completely free! No watermarks, no signup required, and no hidden costs. All processing happens in your browser for complete privacy.
We support all major image formats including JPEG, PNG, WebP, and GIF. The merged output is saved as a high-quality PNG file.
Upload your photos in the order you want them to appear (left to right), set spacing to 0 for a seamless look, and merge. This creates a panorama-style wide image from your individual shots.
Currently, images are merged in the order you upload them. To change the order, remove images and re-upload them in your desired sequence.
The width equals the sum of all image widths plus spacing. The height matches your tallest image. Very large outputs are automatically scaled to stay within 1920px width for optimal performance.
Upload your 'before' image first, then your 'after' image. They'll be placed side by side automatically. Add a small spacing and border for a clean comparison layout.
There's no strict file size limit. We automatically optimize large images for best performance and smooth browser processing. For optimal results, we recommend images under 10MB each, though larger files will still work.
