Side by Side Photo
Put two photos side by side, or one above the other, and save them as one JPG. Line up two pictures of different sizes, add Before and After labels, and check the final size before you download. It runs in your browser: no app to install, and your photos are never uploaded.

Add two photos
Drop both photos on the box, or tap it to pick them from your gallery or a folder. The first goes on the left, the second on the right. Got them the wrong way round? Press Swap.
Line them up
Choose side by side or top and bottom. "Same height" keeps both photos whole; "Crop to the same shape" trims them into two equal frames. Add labels and a gap if you want them.
Download one JPG
The size in pixels and MB shows above the preview. Save the JPG and post it, send it or print it. Have three or more photos? Merge JPG puts them all into one image.
This side by side photo maker does one job. There are no templates or stickers to wade through: you put photos side by side, make them line up, and get a file you can use.
Before and after photos that line up
A before and after picture only works when the two halves match. If one photo is bigger, closer or framed differently, people end up comparing the framing instead of the change you want them to see. A few habits help before you open the tool.
Shoot both from the same spot. Stand in the same place, at the same height, with the same zoom. For a haircut or a fitness photo, keep the same distance from the camera and the same pose. For a room makeover, stand in the same doorway.
Keep the light similar. A dim before photo next to a bright after photo makes the change look bigger than it is, and viewers notice. Take both at the same time of day, with the same lamps on.
Use matching frames. Choose "Crop to the same shape" so both photos fill equal frames. The crop is taken from the centre of each photo, so keep the subject in the middle when you shoot.
Label them. Turn on Before · After to write the words on each photo, in a dark band that stays readable on light and dark pictures alike. Choose Custom for your own words, such as "Day 1" and "Day 90", "2019" and "2025", or "Original" and "Edited". The labels can sit at the top or the bottom of each photo.
That makes it a quick before and after photo maker for fitness progress, renovations, hair and makeup, cleaning jobs, and photo edits you want to show a client.
When the two photos are different sizes
Two photos rarely come out the same size. One may be from a phone and the other from a camera, or one may be upright and the other sideways. The tool has two ways to line them up.
Same height (no crop). Both photos are scaled to the height of the shorter one, so the top and bottom edges line up and nothing is cut off. An upright photo next to a sideways one stays that way, so one half is wider than the other. In top and bottom mode this setting becomes Same width: both photos take the width of the narrower one.
Crop to the same shape. Each photo is trimmed from the centre into an equal frame, so the two halves are exactly the same size. Pick Original to use the shape of the first photo, or a fixed shape for the finished image: 1:1, 4:5 or 16:9. Use this for before and after comparisons, where equal halves matter more than keeping every edge.
Photos are never enlarged. The bigger photo is scaled down to match the smaller one, so the result is as sharp as your smaller photo. If both photos are very large, the finished image is shrunk to a size every browser can save, and the tool tells you by how much.
Sizes for Instagram and other apps
Social apps crop pictures that don't fit their shapes, and a side by side photo can lose half a face that way. Make the finished image the shape the app expects. Choose "Crop to the same shape", then:
1:1 for a square. Each photo becomes a tall half and the result is a square, which every feed shows without cropping. A standard square post is 1080 × 1080 pixels.
4:5 for portrait. A little taller than wide, it takes up more of the screen in the Instagram feed. The usual size is 1080 × 1350 pixels. Each photo becomes a narrow half, which suits people and tall subjects.
16:9 for wide screens. For a YouTube thumbnail, a slide or a website banner. In top and bottom mode, 16:9 gives two wide strips, one above the other.
The Instagram feed takes images from 1.91:1 landscape to 4:5 portrait. Two sideways photos placed side by side at the same height are usually wider than 1.91:1, so the app would trim the sides; pick 1:1 or 4:5 instead.
Put two pictures side by side on iPhone, Android or a computer
You don't need an app to put two pictures side by side. This page works in the browser on any phone or computer, and your photos stay on your own device the whole time.
iPhone and iPad. Open this page in Safari or Chrome, tap the box and choose your two photos from the photo library. Set the layout and tap Download JPG. The image goes to Files or Downloads, and you can save it to Photos from there.
Android. Open the page in Chrome, tap the box and pick two photos from your gallery or files. The JPG is saved to your Downloads folder, where your gallery app can usually find it. Google Photos and Samsung Gallery have collage options too, handy for a quick layout; use this page when you want both photos the same size, Before and After labels, or an exact shape such as 4:5.
Windows, Mac and Chromebook. The page works the same way in Chrome, Edge, Safari and Firefox. Drag two files straight from a folder onto the box, and the JPG is saved to your Downloads folder.
There is nothing to install and no account to make, so it also works on a work or school computer where you can't add software.
Questions
How do I put two pictures together side by side?
Add both photos to the tool at the top of this page, keep "Side by side" selected and download the JPG. Choose "Same height" to keep both photos whole, or "Crop to the same shape" for two equal halves.
What is it called when two photos are side by side?
Usually a side by side photo or a split image. The old word is diptych, a pair of pictures hung together. When the point is to show a change, it is a before and after photo, and most apps file the feature under collage.
How can I create a side by side photo for free?
Use this page. It is free, needs no sign-up and puts no watermark on your image.
Can I put one photo above the other instead?
Yes. Choose "Top and bottom". "Same height" becomes "Same width", and the fixed shapes still apply to the whole image, so 1:1 gives two wide halves stacked into a square.
Will my photos lose quality?
The bigger photo is scaled down to match the smaller one, and the result is saved as a high-quality JPG. Nothing is enlarged, so the finished image is as sharp as the smaller of your two photos.
Are my photos uploaded anywhere?
No. The two photos are combined in your browser on your own device. They are not sent to our server or to anyone else.
