Frequently Asked Questions
How many images can I merge at once?+
Up to 4 images in a single operation. Choose side-by-side (horizontal), top-to-bottom (vertical), or 2x2 grid layout.
Do all images need to be the same size to merge them?+
No. The tool automatically scales images to match the largest dimension in your chosen layout direction. You can also set a fixed cell size for uniform results.
Can I adjust the gap between merged images?+
Yes. A gap slider controls spacing from 0 (seamless) to 20px. You can also set a custom background color for the gap areas.
What is the output format when merging images?+
PNG, which supports transparency and maximum quality. This ensures logos, screenshots, and images with text stay crisp in the merged result.
