A fair before and after
For a fair comparison, both pictures should show the same framing. Zoom them in mosa so the horizon and subject sit at the same height.
Two pictures, one photo
Two photos side by side, in seconds.
Before and after, then and now, two angles on the same moment. Sometimes all you need is two pictures next to each other. In mosa you pick the photos and the image is done, with or without a border.

Tips for side-by-side pictures
Portrait side by side, landscape stacked
Two portrait photos fit nicely side by side in a square or 4:5 image. Two landscape photos work better stacked.
Three pictures as a triptych
Three narrow strips side by side tell a short sequence: beginning, middle, end. The Triptych template is made for this.
Pick the format for where it goes
Square 1:1, portrait 4:5 or 3:4, story 9:16 and landscape 16:9 are available. You can switch formats at any time.
Questions about photos side by side
Short answers.
Can I combine two photos without a white border?
Yes. Set the border in mosa to zero and the two pictures meet edge to edge.
Can I stack them instead?
Yes. For two photos there are side-by-side, stacked and offset layouts, and you drag the divider freely.
Does the image quality suffer?
mosa works with the originals from your library. How sharp the result is depends mainly on how far you zoom into a photo.
Can I do it without an app?
Yes, with the “Combine Images” action in the Shortcuts app. It joins photos side by side, stacked or in a grid, but offers no border choice, no text and no formats.
Is there a watermark?
No. mosa is free and never adds a watermark.
