Free Online Photo Joiner — Combine Photos While Preserving Aspect Ratios
Join multiple photos into a single composite image with our free online photo joiner. Unlike grid tools that crop your images into uniform cells, our photo joiner preserves each photo's original aspect ratio — landscape photos stay wide, portrait photos stay tall. This makes it perfect for creating before/after comparisons, photo strips, product showcases, image galleries, and portfolio grids. Simply upload your photos, set the number of columns, adjust spacing, and download your result. All processing happens locally in your browser for complete privacy.
Upload 2 or more photos. They will be joined in the order they appear.
Set the number of columns and adjust the gap to customize the layout.
Download your joined image as a high-quality PNG when you're satisfied.
Tips for Using the Photo Joiner
- For before/after comparisons, use 2 columns with 2 photos. The equal layout creates a clean side-by-side comparison.
- Photos keep their original aspect ratios, so mixing landscape and portrait images creates an organic, gallery-like layout.
- Set gap to 0 for a seamless, edge-to-edge join — great for creating panoramic-style composites from overlapping photos.
Frequently Asked Questions — Photo Joiner
Is the photo joiner free?
Yes, completely free. No registration, no hidden charges, no watermarks, and no file size limits. All processing happens locally in your browser using the Canvas API.
How is this different from Image Grid Layout?
Unlike Image Grid Layout which forces all images into uniform cells (cropping or adding whitespace), Photo Joiner preserves each photo's original aspect ratio. Landscape photos stay wide and portrait photos stay tall, creating a more natural, gallery-like arrangement.
How many photos can I join?
You can upload between 2 and 99 photos. They will be arranged in the grid according to your specified number of columns, flowing left-to-right and top-to-bottom.
What image formats are supported?
All common image formats are supported: JPG, PNG, WebP, BMP, GIF, AVIF, and more. The downloaded result is saved as PNG to preserve quality.
Can I reorder the photos before joining?
Yes. The upload area shows your photos in the order they will appear. You can drag to reorder them before generating the joined image.
What happens to very large photos?
Each photo cell has a maximum dimension of 2000 pixels. Larger photos are downscaled proportionally. The total output canvas is limited to 50 megapixels (50,000,000 pixels) for reliable browser performance.
What background color is used?
The output uses a white background. If photos in the same row have different heights, the shorter photos will appear with white space above and below within their cell boundaries.
