Combine images

How to combine pictures into one

1. Add your pictures. Drop two or more anywhere on the page, paste them, or click the box to choose files. Pictures added together are listed in name order, with img2 before img10, and you can change the order afterwards.
2. Put them in order. Use ▲ and ▼ to move a picture, and ✕ to take one out. The number on the left is the picture's place in the result.
3. Choose how to arrange them: Side by side, One above the other or In a grid. The preview below the options changes as you go, and a line under it tells you the size of the result in pixels.
4. Choose the spacing, the background and the file type (all explained below).
5. Press Create the picture. The result is saved by your browser as combined.jpg, combined.png or combined.webp.

You can add more pictures at any time with Add more pictures. Your original files are never changed.

Side by side and one above the other

Pictures are rarely the same size, so the first question is how to make them fit together. For Side by side the choice is called Same height, and for One above the other it is Same width:

As an example, take three photos of 4000 × 3000, 3000 × 4000 and 4000 × 3000 pixels, side by side. With the shortest picture every photo becomes 3000 pixels tall, so the portrait one is scaled down to 2250 × 3000, and the result is 10250 × 3000. With the tallest picture they all become 4000 pixels tall and the result is 13667 × 4000. Stacked one above the other with the narrowest picture, the same three photos make a picture of 3000 × 8500.

In a grid

A grid puts the pictures in rows, left to right and top to bottom, with the number of Columns you choose. Every picture gets a cell of the same size, and a last row with fewer pictures leaves its empty cells as background. Two choices shape the grid:

• Cell size is the size of the first picture (the default), the average size of all of them, or an exact width and height in pixels.
• In each cell is Fill the cell (the default) or Fit the whole picture. Filling scales the picture until the cell is covered and trims what hangs over, equally on both sides, so the middle of the picture is what you see. Fitting shows the whole picture, scaled to fit inside the cell, and the rest of the cell shows the background color.

For example, six phone photos of 3024 × 4032 pixels in three columns, with 20 pixels of space and a 20 pixel border, make a picture of 9152 × 8124. A contact sheet of twelve 1024 × 1024 pictures, in four columns of exact 256 × 256 cells with 8 pixels of space and border, is 1064 × 800.

Space, border and background

• Space between is the gap in pixels between neighboring pictures, from 0 to 2000.
• Border around is the margin in pixels around the whole result.
• Background is the color that fills the space, the border, and any part of a cell that a picture does not cover. It starts white. With PNG or WebP you can tick See-through to leave those areas empty instead.

The space and the border are in pixels of the full-size result. If the result is made smaller (see below), they shrink with everything else.

File type, quality and size

Largest size lets you cap the longest side of the result at 4096, 2048, 1920 or 1080 pixels. If the result would be bigger, everything, including the space and border, is scaled down together. For the 10250 × 3000 example above, a 4096 limit gives 4096 × 1199 and a 1920 limit gives 1920 × 562. Leave it on Full size to keep every pixel.

Limits

• Browsers will not draw a picture wider or taller than 16,384 pixels, or with more than about 120 megapixels. If a result would be bigger, it is made smaller to fit and the line under the preview says so. Ten 4000 × 3000 photos side by side, for example, would be 40,000 pixels wide, so they come out at 16382 × 1229. Use a stack or a grid for many big photos, or choose a smaller largest size.
• You need at least two pictures. With one, the button stays off and the page asks for another.
• Big photos use memory while the result is made. The preview uses small copies. When you press Create, each picture is opened at full size one at a time, drawn, and let go, so a long list does not fill the memory.
• Phones: very large results can be too much for a phone's browser. Choose a smaller largest size if it fails.

Common uses

• Before and after. Two pictures side by side with a small space, at the same height.
• A long screenshot. Screenshots of the same width stacked one above the other. Three phone screenshots of 1170 × 2532 pixels make a picture of 1170 × 7596.
• A collage or a grid for social media. A grid with a border, filled cells and one background color.
• A contact sheet. Many pictures, small, in one image, to look at a whole folder at once. This is handy when you are preparing an image dataset and want to check the set at a glance. The duplicate finder and the guide to picture sizes for training help with the rest.
• A strip of product photos at one height.

What stays the same, and what does not

• Pictures are redrawn, not pasted byte for byte. Each one is scaled by your browser with its high-quality setting, and the result is saved as a new picture, so JPG and WebP results are compressed again. Keep your originals.
• Metadata is not kept. The result is a fresh picture, so camera details and GPS location from the originals are left behind. The phone rotation tag is applied first, so pictures keep looking upright. See our EXIF guide.
• HEIC photos work through the same decoder our image converter uses. A GIF is used as its first frame.
• To resize or trim the pictures first, use the bulk image resizer or the crop tool. To make the result smaller in file size, the image compressor can help.

Privacy

• The pictures are combined inside this tab. The files on your disk are never changed or deleted, and the result is made by your browser and saved where you choose.
• For what the site collects and keeps, see our privacy policy.
