Put 2 to 9 photos in one grid
Choose a file to start.
Imagera's free photo collage maker lets you combine photos into one picture in your browser on a phone, tablet or computer. Choose 2 to 9 images (JPG, PNG, WebP or HEIC), pick a layout and adjust the gaps between them. It suits family recaps, product collections and before-and-after comparisons. Each photo is cropped to fill its cell, and the finished collage is saved as a JPEG. Assembly happens on your device. 2 free downloads, 8 more after sign-in.
Published · Updated · by the Imagera teamImagera is a browser-based AI studio for images, video, music and voice, so you do not need a separate app and account for every model. Pricing is credit-based: one balance covers every tool, and each job shows its credit price or estimate before you run it.
















A square collage at the full output size contains 2160 × 2160 pixels, or 4,665,600 pixels altogether. That total is shared by every photo and gap.
With no spacing, a nine-cell square grid at 2160 × 2160 gives each photo 720 × 720 pixels. Wider gaps leave fewer pixels for the pictures.
At a chosen print density of 300 pixels per inch, a 2160-pixel edge measures 7.2 inches. This calculation does not guarantee sharp source photos or set printer metadata.
A collage needs at least 2 source pictures. It cannot create a missing view; the linked Ultra HD Image Generator can make a separate image from a description for you to add.
Try Ultra HD Image GeneratorStart with a small set that tells one story: a trip, a product from several angles or a before-and-after pair. The tool accepts 2 to 9 photos for a single finished picture. Ten, twenty or thirty photos do not fit in one run.
For a larger collection, make separate collages in smaller groups. Adding more pictures also makes each subject smaller in the final composition. Leave out near-duplicates when a face, label or product detail needs room.
The Layout choices are Auto (fits your photos), 2 side by side, 2 stacked, 3 with one large, 4 grid, 6 grid or 9 grid. Start with Auto (fits your photos) when your set has an uneven count: the automatic arrangement handles five, seven or eight pictures without asking you to fill a larger grid.
Choose the overall Shape from 1:1 Square, 4:5 Portrait, 9:16 Story or 16:9 Wide. Changing that shape changes the cells too. A fixed layout needs enough pictures to fill its spaces; when you add more than it holds, it uses the first pictures in your selection. Check the photo count shown with the result.
Each picture fills its cell completely. If the shapes differ, the engine trims the sides or the top and bottom. The crop is centered horizontally and favors the upper part slightly when trimming vertically. It does not detect faces or offer a handle to move each crop.
Try a different layout or overall shape when a face is cut off. You can also prepare the source in the separate Image Cropper. Pictures fill cells in selection order; remove and re-add a picture to move it later, or clear the set and add the pictures in your preferred order.
Spacing controls both the gaps between cells and the outside margin. Start at 12, then reduce it for a tighter composition. Zero removes the gaps; keep Rounded corners at zero too if you want the pictures to meet without curved openings.
In Advanced, Background colors the visible spaces and Rounded corners softens the photo corners. These settings scale with the output dimensions. They are not separate frames around each source photo, and rounding does not make the saved background transparent.
The result is one flattened JPEG with a target long edge of 2160 pixels. A browser canvas limit can reduce that size. Check the actual dimensions beside the result; selecting larger source photos does not increase the target output dimensions.
Cropping, resizing and JPEG compression can change detail. Inspect small faces and lettering in the saved file before printing. This tool has no custom paper size, DPI setting or PDF export. For an A4 page or a specific photo-paper size, place the finished picture in a print-layout app and check its fit there.
Use a supported mobile or desktop browser to choose pictures from your device. The browser reads the files, crops each one and draws the collage locally. Your photos are not uploaded for this assembly. The page still needs to load its code, including a converter when an input needs one.
The collage engine draws the source pictures one at a time, but large inputs still need memory during preparation. If a phone struggles, try smaller copies or fewer pictures. Keep the originals so you can make another version without starting from an already-compressed collage.
The collage arranges pictures you provide; it does not generate another scene. If your set needs an illustration or a product concept, the linked Ultra HD Image Generator creates a separate picture from a description. Review that image before adding it, especially when your collage documents a real event.
For a caption, open the finished collage in Add Text to Photo. For separate tiles cut from one picture, use Image Grid Splitter. Those are different finishing jobs: this tool brings several pictures together into a single file.
Choose 2 to 9 JPG, PNG, WebP or HEIC photos. Check their selection order before arranging the grid.
Pick a Layout and Shape. Use the automatic layout when your photo count does not match a fixed grid.
Adjust Spacing, then the background and corners in Advanced. Make the collage and check that every important face or detail remains visible.

Add nine pictures and choose the nine-cell grid. Set the overall shape, make the collage and review all nine crops. This produces one picture containing the whole grid.
No. A single collage is limited to nine source pictures, with at least two needed to begin. Divide a larger collection into smaller sets and make a separate composition for each.
Choose Auto (fits your photos). It balances the pictures across rows according to the canvas shape. Rows can contain different numbers of cells, so an uneven photo count does not require an empty space.
A fixed layout only uses as many pictures as it has spaces, starting at the front of your selection. Choose a larger layout or the automatic arrangement to include more. Too few pictures for a fixed grid produces a message asking you to add more.
Only when each photo already matches its cell shape. Otherwise the cell is filled by trimming the source; there is no fit-with-margins mode or manual crop positioning here. Change the layout or prepare the framing in Image Cropper first.
Remove a picture and add it again to put it at the end of the selection. For a complete rearrangement, clear the pictures and add them in the order you want. The first picture takes the large cell in the featured-photo layout.
Set Spacing to zero and use square corners for touching tiles. To keep a visible gap in another color, change Background instead. The same spacing setting also controls the outside edge.
Increase Rounded corners in Advanced. The curve applies to each photo cell, revealing the chosen background around its corners. It does not round the rectangular outside boundary of the exported file.
Select the collage photos through a compatible phone browser’s file or photo picker. No separate collage app is needed. If preparing the collage exhausts memory, reduce the camera-roll pictures before adding them to the layout.
The assembly uses local image files and a canvas in your browser. It does not send the photos to a server for processing. Loading the website and its code still involves network requests.
It exports a JPEG with a target long side of 2160 pixels; the other side follows your chosen shape. Device limits may reduce the dimensions. The result lists the actual resolution, and there is no custom output-size or format selector.
That depends on the retained detail in each source, the crop and the print size. Every tile gets only part of the output pixel area. Use clear originals and inspect the saved image at the intended size; the tool does not promise lossless or print-ready output.
This editor has preset canvas shapes, not paper dimensions or a PDF exporter. Place its finished image in a page-layout or printing app to choose paper size, margins and scaling. Check that the paper shape does not crop parts of your collage.
Choose the tall Story option under Shape, then review how the pictures fit. The featured-photo layout puts its large picture above the smaller pair on a tall canvas. Save the result and add that image to your Story.
There is no caption control in this tool. Save the assembled picture, then use the separate Add Text to Photo tool to place a caption over it.
No. The canvas is filled with the selected background color and exported as an opaque image. Transparent areas in source pictures show that background rather than remaining see-through in the final collage.
The saved file is a flattened picture, not a project with separate photo layers. Keep your source images and rebuild the arrangement if you need to change positions or crops later.
