How to Put Two Photos Side by Side (Before and After)

Join two or more pictures into one image — side by side, stacked or in a grid, with a border between them. Perfect for before-and-after shots. Free.

3 min read ·

To put two photos next to each other in one image, open Combine Images, add both pictures, choose Horizontal for side by side (or Vertical to stack them, or a Grid), set a border if you want a line between them, and download the combined image as PNG or JPG. It works for two photos or twenty.

Combine photos step by step

  1. Open Combine Images and add your pictures — select several at once.
  2. Choose the Layout Direction:
    • Horizontal — side by side, left to right.
    • Vertical — stacked, top to bottom.
    • Grid Matrix — rows and columns; set the number of Grid Columns.
  3. Under Borders & Spacing, set the Border Thickness and Border Color — a thin white line looks clean; zero for a seamless join.
  4. Choose PNG for screenshots and graphics or JPEG for photos.
  5. Download the combined image.

Before-and-after photos

The classic use. To make a comparison that's easy to read:

  • Same framing: take both photos from the same spot, at the same zoom and angle. Crop them to match with the Image Cropper if they differ.
  • Same size: pictures of similar dimensions line up best. Resize the larger one with the Image Resizer first if they differ a lot.
  • Same light: shoot at a similar time of day; very different lighting makes it look like a different place.
  • Label them: add "Before" and "After" with Add Text to Image after combining.

Side by side suits portrait photos (renovations of a door, a haircut); stacked suits landscape photos (a garden, a room) so each stays large on a phone screen.

Other things to combine

  • Product variants: colours or angles of the same product in one row for a listing.
  • Step-by-step screenshots: stack them vertically to show a process in one image.
  • ID card front and back: stack both sides in one image for a form that allows only one upload. If the form wants a PDF, convert the result with Image to PDF.
  • Photo collages: a 2×2 or 3×3 grid of holiday photos to share as one picture.
  • Comparisons: two designs, two outfits, two options for a vote.

Phones: the same in your pocket

The tool works in mobile browsers. Pick the photos from your gallery, combine them, and save the result back to your photos — handy for posting a before-and-after to Instagram or WhatsApp straight away. For Instagram, check the final shape: a side-by-side pair of portrait photos is wide, and may need fitting into a 4:5 post with the Social Media Image Resizer.

Framing the result

To add an outer frame around the whole combined image — or pad it to a square — use Add Border to Image after combining.

Going the other way

To cut one image into several pieces instead — for an Instagram grid or a panorama carousel — use the Image Splitter.

Tips for a clean result

  • Order matters: images are combined in the order you add them. Add the "before" photo first.
  • Mismatched heights in a horizontal layout leave empty space; crop or resize to similar heights first.
  • Very large photos make a very large combined image. Resize big phone photos to around 1600 pixels first if you're sharing on screen.
  • Choose JPG for sharing, PNG for screenshots with text.

Frequently asked questions

Are my photos uploaded?

No. The images are combined in your browser.

How many images can I combine?

As many as you like, though very large grids of full-size photos produce huge images; resize first for big collages.

Can I add a gap instead of a line?

Yes — set the border colour to match the background (white, for example) to create a gap rather than a visible line.
