How to make a photo collage online

To make a photo collage, add your photos to a collage maker, choose a layout (grid, side by side or stacked) and a size such as 1080 by 1080 for a post, put the photos in order and download one image. The collage maker on this page does it in your browser in under a minute, with spacing, rounded corners and a background color, and without an app or account.

The short answer

Drop two or more photos on the collage maker below. Choose a Layout: Grid for several pictures, Side by side for comparisons, Stacked for a vertical strip. Pick the Size that matches where the collage will go, adjust Spacing, Rounded corners and Background, then press Make collage and download the result as JPG or PNG.

Each photo is scaled to fill its cell completely and cropped from the center, so there are never empty bars. In a grid, if the last row has fewer photos, they stretch to the full width instead of leaving a hole.

Choosing a layout

The layout decides how big each photo can be, and that matters more than any decoration. A grid divides the space evenly and works best when all photos are equally important: a trip, a product range, a team. Side by side places photos in one row, the classic format for before and after pictures or two options to compare. Stacked puts them in one column, which suits tall formats such as stories.

In the grid the tool chooses the number of columns from the number of photos and the shape of the canvas. On a square post it arranges them like this:

PhotosGrid on a square postCell shape
22 side by sideTall, about 1 by 2
32 on top, 1 full width belowMixed, the last photo is wide
42 by 2Square
53 on top, 2 belowTall above, square below
63 by 2Tall, about 2 by 3
93 by 3Square
124 by 3Slightly tall

The right size for posts, stories and print

The Size menu has five canvases. They are the common pixel sizes for social networks plus an A4 page at print resolution. Spacing and corners scale with the canvas, so a collage looks the same whether you make it for a phone or for paper.

  • Square post, 1080 by 1080: works everywhere, from Instagram and Facebook to WhatsApp and marketplaces. Best for 4 or 9 photos.
  • Portrait post, 1080 by 1350 (4:5): takes more space in the feed than a square. Profile grids may show posts cropped to a narrower shape, so keep faces away from the very top and bottom.
  • Story, 1080 by 1920 (9:16): for stories, reels covers and status updates. Two or three stacked photos fit well. Leave room at the top and bottom, where the app places its buttons.
  • Landscape, 1920 by 1080 (16:9): presentations, YouTube, desktop wallpapers and side by side comparisons.
  • A4 print, 2480 by 3508: an A4 page at 300 DPI, sharp enough for a printer or a print shop. A 3 by 4 grid of 12 photos on A4 makes a nice photo sheet.

Picking photos that work together

A collage looks calm when the photos share something: similar light, similar colors or the same subject at different moments. Mixing a dark indoor shot with a bright beach photo is fine for a memory board, but for a product or a portfolio choose pictures taken in similar conditions.

Because every photo is cropped to fill its cell, think about the shape. Two portrait phone photos side by side on a square canvas lose little; two landscape photos side by side on a square canvas lose their left and right edges. For a before and after of two horizontal photos, choose Stacked on a square or Side by side on Landscape. Keep the subject near the center of each photo, since the crop is taken from the middle.

Order tells the story. Put the strongest picture first (top left), keep before on the left or on top, and drag the rows in the list or use the arrow buttons to rearrange. Sort by name is useful when your camera already numbered the files in the right order.

Spacing, borders and background

Spacing adds a gap between the photos and around the edges, filled with the Background color. A thin white gap (around 8 to 16 on the slider) gives a clean, magazine look. No gap makes the collage read as one picture, good for panoramas or a seamless grid. A wide gap with a colored background frames the photos like a poster.

Rounded corners soften the cells; small values look modern, large values work for playful, sticker like layouts. Choose a background that appears in the photos (a sand tone for beach photos, the brand color for products) or neutral white, off white or black. Rounded corners together with zero spacing rarely look good, because the corners leave small background triangles between photos.

JPG or PNG, and common problems

Choose JPG for photos you will post or send: the file is much smaller and every network converts uploads to JPG anyway. Choose PNG only for collages of screenshots, graphics or text, or when you will edit the collage further, because PNG keeps every pixel exactly but can be several times larger.

  • Heads are cut off: the photo was cropped from the center. Use a layout where the cell shape matches the photo (Stacked for landscape photos, Side by side for portrait photos) or crop the photo yourself first.
  • The collage looks blurry on Instagram: the app compresses images. Upload the 1080 pixel JPG directly instead of a screenshot of it.
  • The print looks soft: use the A4 print size and photos of at least about 1000 pixels on the short side for a 12 photo sheet.
  • An iPhone photo will not open on an older computer: HEIC files are supported here, but if a browser cannot read them, convert them to JPG first.

  2. Put them in orderDrag the rows or use the arrows; Sort by name uses the file names.
  3. Choose layout and sizePick Grid, Side by side or Stacked, then a size such as Square post, Story or A4 print.
  4. Style itSet Spacing, Rounded corners and Background, and choose JPG or PNG.
  5. Make and downloadPress Make collage, check the preview and download the image.

Frequently asked questions

How do I put two pictures side by side?

Add both photos, choose Side by side and press Make collage. For two landscape photos use the Landscape size so less is cropped; for two portrait photos the Square post works well.

How many photos can a collage have?

There is no fixed limit, but each photo gets smaller as you add more. On a phone screen 2 to 9 photos are easy to see; on an A4 print up to about 12 to 16 still look good.

Are my photos uploaded to make the collage?

No. The collage is drawn in your browser and the photos never leave your device. There is no account and no watermark.

Can I make a collage on my phone?

Yes. Open the page in your phone's browser, choose photos from your gallery and arrange them with the arrow buttons. The finished image is saved to your downloads or photos.

What size is best for printing a collage?

Use A4 print, which is 2480 by 3508 pixels, the size of an A4 page at 300 DPI. Photo labs print it sharply at A4 and also at smaller sizes with the same proportions.

Why are parts of my photos missing?

Each photo is cropped from the center to fill its cell without empty bars. Choose a layout whose cells have a similar shape to your photos, or crop the photos before adding them.
