Are the photos resized to match each other?

Only downwards. Every measurement is taken from the narrowest photo in the set, so wider ones are scaled down to fit and nothing is ever enlarged past its real resolution.

How many photos can I combine at once?

There is no fixed limit. The real ceiling is the canvas itself — 16384 pixels on the longest side, chosen because it is safe in every browser. Go past it and the tool scales the result down and tells you it did.

Can I make a 2 × 2 collage?

Yes — choose the grid layout with equal cells and set the columns to 2. The screenshot preset stacks images vertically with no gap, which is the other layout people come here for.

Is anything uploaded while I am arranging the photos?

No. The pictures are read straight from your device into the page and stitched together on a canvas; nothing is sent anywhere, which is also why it works with no network.

Drop in as many photos as you like, drag them into the order you want, and they are stitched into a single image — stacked, side by side, or arranged in a grid. Every size is measured from the narrowest photo, so nothing is ever enlarged.
