Pro Tips for Perfect Merges
Resolution Matching
For seamless merges, start with images of similar resolution and aspect ratio. Use our “Magnify the small to match” option when combining different sized images.
Border Techniques
Subtle borders (2-5px) in neutral colors (white, gray) create professional separation between images without distracting from the content.
Export Quality
For print materials, merge at original resolutions. For web use, resize images first (1000-2000px wide) to reduce file size while maintaining quality.
