Combining two images into one is common: before/after comparisons, a long screenshot cut into two pieces, two photos for a single post. Here's how to merge two images easily.
Common use cases
- Comparisons: before/after, side-by-side of two options
- Long image repair: a screenshot cut in two, needing to be rejoined
- Material merging: two assets into one design
- Sharing: two photos in a single shareable image
Two merge directions
Horizontal — images side by side. Best for comparisons like "before vs after".
Vertical — images stacked top to bottom. Best for joining two screenshots into a long image.

Tips
