How many pictures can go in one collage?

Twelve. Past that the cells get too small to be worth cropping a photograph into, and the browser is holding twelve decoded images in memory at once already. If you drop in more than twelve, the tool says how many it left out rather than silently taking the first few. The four layouts arrange whatever number you give them. Feature gives the first picture a block two cells wide and two tall and puts the rest around it. Grid uses equal rows and fills each one edge to edge, so a count that does not divide evenly gives the rows with fewer pictures wider cells instead of leaving a hole. Row and Stack line the pictures up in one strip, across or down. Whichever you pick, the cells tile the collage exactly, so there is no stray band of background down one side.

Can I make the collage a set shape, like square, a 4 × 6 print or a wallpaper?

Yes. The Shape menu under the layout buttons fixes the outline: Square 1:1, Portrait 4:5, Print 2:3 (a 4 × 6 print stood upright, and a 24 × 36 poster), Landscape 3:2 (a 4 × 6 print on its side), Story 9:16, Phone 9:19.5 (recent iPhone screens), Laptop 16:10 (many laptops and older MacBooks), Wide 16:9 and Facebook cover (820 by 312). Fit the layout, the default, lets the outline grow with the layout instead. The layout still decides where each picture goes, and each one is cropped to fill its cell, so a shape never squashes a photograph. The download keeps the shape's ratio to within a pixel and its longest side follows your largest picture, up to 6,000 pixels on the long side or 20 megapixels, whichever comes first. That is plenty for a 4 × 6 print at 300 dpi (1,800 by 1,200), but not for a 24 × 36 inch poster at full print resolution, which needs a size set in inches and a DPI: the Poster Maker does that.

Can I make a collage of just two photos?

Yes. Drop in two pictures and pick Row to put them side by side, Stack to put one above the other, or Feature to give the first one two thirds of the width. Grid with two pictures also puts them side by side. Pick a shape as well if the pair has to fit a square post or a phone screen, and drag one onto the other to swap them.

What resolution does the collage save at?

Bigger than it looks on screen. The export follows the largest picture you dropped in: a collage built from 4032 pixel phone photographs saves at 4032 pixels on its longest side rather than at the few hundred pixels the preview occupies. The exact number is printed in the Download size box under the collage and in the Export line, and that is the canvas the file is encoded from, so the label and the download cannot disagree. Very large collages are brought back in proportion to what a browser canvas will hold, which is why the printed number is the one to read rather than a number you calculated yourself.

Are my pictures uploaded anywhere?

No. There is no server in this. Each file is read in the page, decoded with the browser's own image decoder, drawn onto a canvas, and encoded back out as the file you download. No image byte is sent to an endpoint, to analytics or to error reporting, and nothing about a picture is written to your browser's storage either: the tool remembers your layout, gap, background and format between visits, and that is all it remembers.

Why does a phone photo come out sideways in other collage tools?

Because a phone usually stores the picture the way the sensor read it and adds an EXIF orientation tag saying which way up it should be shown. A tool that ignores the tag saves the raw frame, so a portrait comes out on its side. This one reads the tag out of the file's own bytes, then checks whether the browser already applied it when it decoded the file, which current browsers do and which it can tell because a quarter turn swaps a picture's width and height, and turns the picture itself only when the decoder did not. That is the difference between one rotation and either none or two.

Can I have a transparent background between the pictures?

Yes, with the Clear background and the PNG format. JPEG has no transparency at all, so a clear background is saved as white there and the tool says so under the readout rather than letting you find out in the file. The gap control sets how much background shows: none for edge to edge, or 8, 16 or 32 pixels of the collage's own scale between the cells.

How do I change the order of the pictures?

Drag one picture onto another on the stage and it takes that place, with the rest shifting along, or move the keyboard focus onto a picture and use the arrow keys to move it earlier or later and Backspace to remove it. The first picture is the one that gets the big cell in the Feature layout, so reordering is how you choose which photograph leads.

Are the pictures stretched to fit their cells?

No, they are cropped. Each picture is scaled until it covers its cell and the middle of it is kept, so a portrait in a wide cell loses its top and bottom rather than being squashed. Nothing is ever distorted to fit, which is why a tall photograph in a Row layout shows a band from its middle.

Does it work on an iPhone, an Android phone or a computer?

Yes, in any current browser, with nothing to install and no app to download. Add pictures opens your photo library on a phone and a file picker on a computer, and dropping files onto the stage works on a computer too. On an iPhone the download goes to Downloads in the Files app, and Share then Save Image puts it in Photos. On Android it goes to the Download folder, which the Files app and most gallery apps show.

Is there a watermark, or a sign up before the download?

Neither. Making and downloading a collage needs no account and costs nothing, and the file holds your pictures and the background you chose, with no logo or watermark added.

Collage Maker

Drop in up to twelve pictures, pick one of four layouts and a shape, and download the collage as a PNG or a JPEG. The shape can follow the layout, or be fixed at square, 4:5, a 4 × 6 print, a phone or laptop wallpaper, 16:9 or a Facebook cover, and the pictures are cropped to fill it rather than stretched. The pictures are decoded in this browser tab and drawn onto a canvas here, so nothing is uploaded, there is no account, and the only limit on file size is the memory of the device you are on. The layout on screen is the layout in the file, at the pixel size printed under it, and a photograph carrying an orientation tag is turned upright rather than saved on its side.

Lossless, so every pixel is kept as drawn, and the format that can keep a clear background. The download size follows the largest picture you dropped in, so a collage of phone photographs saves far bigger than it looks on this screen.

The file you download is the canvas at the pixel size printed under it, at full resolution rather than the size shown on screen, and photographs are rotated to match their own orientation tag so a phone picture is not saved sideways. Your pictures are decoded in this tab and never uploaded, and a small source picture cannot be made any sharper than it already is.
