How to Make a Half-and-Half Photo

2026-08-11 · 2 min read

You'll get a lopsided result if you eyeball the split, because a clean half-and-half photo depends on both halves matching in height before you place them.

  4. Frequently asked questions

A half-and-half photo splits two images down the middle, each taking up exactly half the frame, side by side with no gap. The fastest way to make one is a free merge tool set to a 50/50 side-by-side layout with no gap between images.

How to make a half-and-half photo

  1. Pick two photos with a similar height, or crop them to match before uploading.
  2. Upload both to the merge tool and choose a side-by-side layout.
  3. Set the gap to zero so the two halves meet with a clean seam instead of a visible border.
  4. Check that both images fill the frame at an even 50/50 split, then download.

Getting the split even

A half-and-half photo looks off the moment one side is noticeably taller or wider than the other. If your two source photos aren't the same aspect ratio, crop them to match before merging rather than stretching one to fit.

Portrait photos split cleanly with a vertical line down the middle. Landscape photos usually look better split horizontally, top half and bottom half, instead of forcing a vertical seam.

Common half-and-half photo uses

  • Before and after shots, split down the middle instead of stacked.
  • Two friends or family members shown together in one portrait-style image.
  • Two locations or moments shown as one split scene for social posts.
Want more than a strict 50/50 split, or more than two photos? The side-by-side layout guide covers custom ratios and grids.

Frequently asked questions

What is a half-and-half photo?
A half-and-half photo is one image made from two photos, each filling exactly half the frame side by side with no gap, commonly used for before/after shots or split portraits.
Do both photos need to be the same size for a half-and-half photo?
They should share the same height and aspect ratio for a clean 50/50 split. Crop mismatched photos to match before merging rather than stretching them.
Can I make a half-and-half photo for free?
Yes. A browser-based merge tool set to a zero-gap side-by-side layout produces a clean half-and-half split at no cost.
