Merge images into one picture, side by side or in a grid

How to merge images into one picture

To combine two pictures, select both, keep Side by side or pick Stacked, and press Merge. For anything more, follow these steps.

1. Press Select images and choose two or more pictures, or drop them on the page. JPG, PNG, WebP, AVIF, GIF, BMP, TIFF, ICO and iPhone HEIC photos all open.
2. The pictures line up as cards under the stage. Drag a card to move it, or click a card and press Alt with the left or right arrow key. The merged picture follows that order: first on the left in Side by side, first at the top in Stacked.
3. Pick a Layout: Side by side, Stacked or Grid.
4. Set the Gap, the Outer margin, the Corner radius and the Background.
5. Choose the Longest side and the format under Save as, then press Merge.
6. Save the result. It is called merged, with the format's ending, such as merged.jpg.

The stage shows the whole merged picture as it will be saved, and it is drawn again each time you change a setting or the order. Add pictures brings in more, and each card has a button to remove that picture. You can merge up to 50 pictures in one picture. Below two, the panel says Add at least two pictures, and above 50 it asks you to remove some.

Put photos side by side, stacked or in a grid

The Layout tiles decide how you combine images: in one row, in one column or in a grid. Each one handles pictures of different sizes in its own way, and the help line under Pictures says which.

In Side by side and Stacked nothing is cut off: each picture is scaled whole to share a height or a width. That is the easy way to put photos side by side when they were taken on different cameras or at different sizes. For a mirrored pair, flip a photo first, then merge it with the original, Side by side. For a reflection, put the original above an upside-down image of itself, Stacked.

In a Grid, every cell has the same shape, worked out from your pictures, so pictures of a similar shape fill their cells best. Until you choose, Columns follows the number of pictures: four pictures make two columns, nine make three. If the last row is not full, the Background shows in the empty cells.

• Under Pictures, Keep them whole fits each picture inside its cell, whole, with the Background around it if its shape differs.
• Fill the cells crops each picture to fill its cell, so the grid has no gaps but the edges of some pictures are cut. It is offered in Grid only.

For a row or grid of equal squares, crop each picture to square first, or make each image square by adding space around it, so nothing is cut. With every picture the same shape, each one fills its place exactly.

Gap, margin, rounded corners and background

Three sliders shape the space around the pictures. Each runs from 0 to 10 %, in steps of 0.5, and is measured against the shorter side of the layout, so the look stays the same whatever size you save at.

• Gap is the space between neighbouring pictures. It starts at 1 %, a thin line. Set it to 0 to join images edge to edge.
• Outer margin is a frame of Background around the whole picture. It starts at 0.
• Corner radius rounds the corners of every picture. It starts at 0, square corners.

To stitch images such as screenshots into one long picture, pick Stacked and set the Gap to 0. The pictures are placed whole, edge to edge, and overlapping parts are not blended as in a panorama: anything two shots share shows twice. In a long stack, Longest side sets the height, so the more you stack, the narrower each picture comes out.

The Background fills the gap, the margin and any empty space in a grid. Pick White, Ink, Black or Transparent, or choose any colour with the last swatch.

For round pictures, such as a row of team headshots, circle crop each image first and save it as PNG. The Background then shows around each circle.

Transparent leaves the space see-through, which is handy if you place the merged picture on a coloured page or slide later. A transparent picture is saved as PNG or WebP, so JPG is switched off under Save as while it is picked and shows No transparency.

Size and format of the merged picture

Longest side sets the size of the result: 1,080, 2,048, 4,096 or 8,192 pixels, with 2,048 to start. The whole merged picture is scaled so its longer side is exactly that, and the other side follows the layout. The panel shows the size and an estimate of the file size before you press Merge.

• 1,080 px suits a social post or a chat message.
• 2,048 px suits most web pages and documents.
• 4,096 px or 8,192 px keeps detail when many pictures share the space, as in a large grid.

The result is scaled to fit the size you pick, so small pictures can be enlarged and may look soft. If they are small, pick a smaller Longest side. For an exact size afterwards, such as 1200 by 630, use Resize image.

You can merge photos of different formats together: a JPG, a PNG and any other format from step 1 can share one picture. Whatever went in, Save as offers JPG, PNG and WebP. JPG is the default and suits photos: it is saved again at high quality. PNG keeps every pixel and suits screenshots and text, but makes larger files. WebP is usually smaller than both. The merged picture is drawn fresh, so it carries no location, camera or date details from the pictures you started with.

Privacy, limits and related tools

• Your pictures are joined inside your browser. They are never uploaded, and our server does no picture work.
• It is free, with no account and no watermark. Image tools are not counted in the free daily limit, which applies to document conversions only.
• It works in current Chrome, Edge and Firefox. Very large pictures may be too big for your browser, and a large grid at 8,192 px needs more memory than a pair at 1,080.

Pictures that should be pages rather than one image belong in JPG to PDF. To show them one after another as an animation, turn them into a GIF with Images to GIF instead.
