About the Combine Images
Combine Images joins several pictures into one. Line them up side by side, stack them from top to bottom, or lay them out in a neat grid with as many columns as you like. Choose the space between pictures, a border around the edge, a background colour (or a see-through one for PNG), the largest size you need, and whether to save a PNG or a JPG. A live preview shows the result before you download. The work is done by your browser, so your pictures are not uploaded anywhere.

How to use the Combine Images
- 1Click Select images and choose two or more pictures, or drop them on the page.
- 2Use the arrows to put the pictures in order, and Remove to take one out.
- 3Pick Side by side, Top to bottom or Grid. For a grid, choose the number of columns and whether pictures fill their cell or fit inside it.
- 4Set the gap, border and background colour, check the preview, choose PNG or JPG and a size, then click Download.
Choosing the right layout
Side by side works best for comparisons such as before and after shots, product variations or two views of the same object. Top to bottom suits screenshots, long receipts and step-by-step pictures that read like a story.
Grid is the classic collage. It gives every picture an equal cell, which looks tidy on social media posts, listings and photo cards.
Gap, border and background
- A gap of 10 to 30 pixels separates pictures without wasting space.
- A border adds an even frame around the whole sheet. Leave it at zero for a tight edge.
- White looks clean for documents and shops, black suits photography, and a light grey is gentle on the eye.
- Transparent is useful when you will place the result on another design. Save it as PNG.
Getting the size right for where it will be used
The longest side setting caps the width or height of the finished image. Around 1080 pixels is enough for most social media posts, 2000 works well for web pages and email, and 3000 or more is better for printing.
If the file is too large to send, save as JPG, choose a smaller size, or run the result through Compress Image.
Combining pictures on a phone
Open this page in Safari or Chrome, tap Select images and pick several photos from your gallery. Everything happens on the phone, so private photos are not sent anywhere. Very large sheets may be made a little smaller because phones limit canvas size, and the page tells you when that happens. To go the other way, cut a picture apart with Image Splitter, and for a document, save the sheet using JPG to PDF.

Frequently asked questions
How do I put two pictures side by side?
Add both pictures, keep the layout on Side by side and check the preview. Both are scaled to the same height so the row looks even. Click Download when you are happy with it.
Can I make a before and after image?
Yes. Add the before photo first and the after photo second, choose Side by side or Top to bottom, and give them a small gap. The order in the list is the order in the picture.
What is the difference between Fill the cell and Fit inside?
This applies to grids. Fill the cell crops each picture slightly so it covers its square completely, with no empty space. Fit inside shows the whole picture and leaves background colour around it if the shapes differ.
Can the background be transparent?
Yes, if you save as PNG. Choose Transparent and any gap or border stays see-through. JPG can't hold transparency, so it uses white instead.
Will combining reduce the quality?
Pictures are only shrunk when the finished image would be bigger than the size you chose, or bigger than your browser can handle. Choose a larger longest side and PNG if you want the most detail.
How many pictures can I combine?
There is no fixed limit. A phone can handle a few dozen typical photos. For very large sheets your browser has a size limit, and you will be told when the result had to be made smaller.
Are my images uploaded?
No. The pictures are joined on a canvas inside your browser and never leave your device.
