Combine Images
Pick a row, a column or a grid, set the spacing and the background, and watch the result before you save it. The awkward part of joining pictures is that they are rarely the same size, so this page makes you choose what happens: leave every picture at its own size and fill the gaps with the background, or scale the bigger ones down to match the smallest. It never enlarges anything, because an enlarged picture is a blurry picture.

Your files
Every picture is drawn at its own pixel size and centred; the space left over is filled with the background colour. Nothing is resampled.
The larger pictures are scaled down until the shared edge matches the smallest picture. Nothing is ever scaled up.
Nothing chosen yet.
Where your file goes
Nowhere. This page downloads a small program into your browser, and that program reads the file straight from your disk. The program comes from this site like any image or stylesheet — but your file only ever travels from your disk into your own browser tab.
Why this one
What you get that the big converters cannot offer.
It says out loud what happens to mismatched sizes
Two choices, both described on the page: keep every picture at its own pixel size and pad the shortfall with the background colour, or shrink the larger ones until the edge that matters lines up. Most collage tools pick one silently and you find out from the result.
A preview you can rearrange
The joined picture is drawn before you export it, with arrows to move a picture earlier or later. Change the spacing or the background and it redraws as you type.
Transparency does not get painted over
Tick the transparent background and the result is a PNG with the gaps still see-through. Feed it any PNG or WebP and the result is a PNG, so an image with soft edges keeps them.
Big pictures, no upload queue
Four 6000 × 4000 photos is a 100 MB upload on a site that works by uploading. Here nothing leaves the tab, so the only cost is the second or two your own machine spends drawing.
How to use it
Choose two or more images. They join in the order they are listed.
Pick a row, a column or a grid, then the spacing, the background and what to do about different sizes.
Press Start to see the result, rearrange if you want to, and download it.
When people use it
A before and after in one picture
Two photos side by side say the thing that two separate attachments never quite do.
Several screenshots for one bug report
One image the reader can scroll through, rather than five they have to open one at a time.
A grid of photos for a listing
Marketplaces that only accept one picture per item, and you have six angles of the thing.
Questions
What happens when my pictures are different sizes?
You decide, and the page states both options in plain words. "Keep original size" draws every picture at its own pixel dimensions, centres the smaller ones in the space and fills the rest with your background colour. "Shrink to match" scales the larger pictures down until the shared edge — height in a row, width in a column — is the same as the smallest picture. Nothing is ever scaled up.
What file type do I get?
PNG if any of the pictures you gave it was a PNG or a WebP, or if you asked for a transparent background. Otherwise JPEG, written at quality 92. The rule is there so a picture with transparency never comes back with a solid rectangle where the transparency used to be.
Can I change the order?
Yes, in the preview. Each picture in the list has arrows to move it earlier or later, and the result redraws immediately.
Is there a limit on how many, or how big?
Not from us. The practical ceiling is the browser: a canvas will not go past about 65,000 pixels on a side or roughly a hundred million pixels in total. If your combination would cross that line, the page scales it down to fit and tells you it did — it does not hand you an empty picture, which is what an unguarded canvas does.
Are the pictures uploaded?
No. There is no server. Everything is drawn in your browser from the files on your own disk.
