常见问题解答

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.
