About combining images
Sometimes two photos say more together: a before and after, two products to compare, a child then and now, a screenshot next to the result. This tool puts them into one picture.
Choose side by side or one above the other. The photos are made the same height (or the same width), so the edges line up. Nothing is cropped: each photo keeps its whole picture. Add a gap and a border if you like, and download one PNG or JPG.
The page opens with two boxes, one for each photo. You can add more photos later — three, four or ten in a row.
Everything happens in your browser. Your photos are never uploaded.
Features
- Side by side or one above the other — one click to change

- Nothing cropped — every photo keeps its whole picture
- Gap, border and rounded corners — in any colour
- Two or more photos — add as many as you need, swap or reorder them
- Full size or smaller — up to 1080, 2000 or 4000 px on the long side
- PNG or JPG — one click to download
- Private — nothing is uploaded
How big is the result?
The tool does simple maths. Side by side, the width is all the photo widths added up, plus the gaps, plus the border on both sides. The height is the height of the photos (plus the border).
An example with photo A at 1200 × 800 px and photo B at 600 × 900 px:
| Direction | Sizes | Gap / border | Result |
|---|---|---|---|
| Side by side | Same height, shrink (800 px) | 0 / 0 | B becomes 533 × 800, result 1733 × 800 |
| Side by side | Same height, enlarge (900 px) | 0 / 0 | A becomes 1350 × 900, result 1950 × 900 |
| Side by side | Same height, shrink | 20 / 30 | 1733 + 20 + 2 × 30 = 1813 × 860 |
| One above the other | Same width, shrink (600 px) | 0 / 0 | A becomes 600 × 400, result 600 × 1300 |
| Side by side | Keep the original sizes | 0 / 0 | 1800 × 900, A centred with 50 px above and below |
Same height (smallest) shrinks the bigger photos to the smallest one. No photo is made bigger, so nothing gets blurry. Same height (largest) keeps every pixel of the biggest photo, but the smaller ones are enlarged. One above the other, the same choices are called Same width.
Which size to save
- Full size keeps every pixel. Two phone photos side by side can be 8000 px wide — fine for printing, big for a chat.
- Up to 2000 px is good for email and documents.
- Up to 1080 px is the width social media uses anyway.
- PNG keeps exact pixels (good for screenshots). JPG makes a much smaller file (good for photos). The tool starts on JPG when all your photos are JPG.
A browser can only save a picture up to about 16,000 px on a side. A bigger result is made smaller to fit, and the status line says so.
What people use it for
- A before and after photo — a room, a haircut, a garden, a repair
- Comparing two products, two colours or two designs
- Then and now — a child, a street, a building
- A screenshot next to the result, for a guide or a bug report
- A long strip of photos from a trip, one above the other
- Two pages of a document side by side in one image
Frequently asked questions
How do I put two pictures side by side?
Drop the first photo in the left box and the second photo in the right box. The tool puts them side by side at the same height at once. Click Download the picture.
Can I combine more than two images?
Yes. Click Add more photos and add as many as you need. Drag the thumbnails, or tap two photos in the preview, to change the order.
Will my photos be cropped?
No. Every photo keeps its whole picture. The tool only makes them the same height (or the same width) so the edges line up.
How do I put one picture on top of another?
Choose One above the other. The photos are then made the same width and stacked.
Is there a watermark?
No. The picture you download has no watermark and no logo.
Are my photos uploaded?
No. The photos are combined in your browser and never leave your device.
