How many photos can I include in a collage?

The built-in templates support 2 to 12+ images depending on the layout. For larger grids, use the stitch tool which supports unlimited images in a simple grid arrangement.

Can I control the spacing between images?

Yes. Adjust the gap size and background color between cells. Set spacing to 0 for a seamless grid or increase it for a framed look with a colored border between images.

What resolution is the output?

You can set the output resolution to any size. For social media, 1080x1080 or 1080x1350 pixels are common. For print, set a higher resolution (3000+ pixels on the longest side at 300 DPI).
