Arrange several photos into one picture: grid, row, column or masonry, with gaps, frames, rounded corners and an exact output size.
Places every photo you drop into a cell of one large canvas and draws the result at the size you choose. Grid gives equal cells in rows and columns, Row and Column line the photos up in one direction, and Masonry stacks them in columns at their own proportions so nothing is cropped. Each photo is scaled to fit its cell and centred; gaps, frames, borders and the corner radius are drawn around it. The preview redraws as you change anything, and the badge shows the pixel size and file size you will download.
Six holiday photos in a 3 × 2 grid at 2048 wide with a 12 px gap come out as a 2048 × 1365 JPEG of about 620 KB at quality 90, which is small enough to post anywhere. The same six as Masonry in three columns produce a taller 2048 × 1900 image because portrait shots keep their height. Switching on the Polaroid frame at 24 px thickness turns it into a pinboard look; the frame band comes out of each cell, so the photos themselves get a little smaller.
Use it when several pictures need to travel as one: a before-and-after pair, a product from four angles, a mood board, a story slide with three moments. If you want one photo laid over another, use Overlay Image instead, and if you only need two pictures side by side with no styling, Merge Images is quicker. For a single picture that just needs a border, Blurred Frame Generator or Round Corner does the job without the grid.
Grid cells are equal; extra photos beyond rows × columns are left out, and the panel tells you so. Masonry sets its own height from the photos unless the ratio is Custom. The Size chips fix the overall shape (1:1 for Instagram, 16:9 for a slide); type any width and the height follows. Frames wrap each cell: Simple is a flat band, Polaroid adds the deeper bottom strip, Shadow floats the photo, Fancy scallops the corners, and Inner padding is the background-coloured gap between frame and photo. Corner radius rounds the whole collage; export as PNG or WebP to keep the corners transparent.
How many photos can I add? As many as your device can hold in memory; twenty 12-megapixel photos is fine on a laptop. Grid shows only rows × columns of them, so pick 4 × 4 or switch to Masonry for a big set.
Why are my photos cropped? They are not cropped, they are scaled to fit their cell with the background colour showing around them. Choose a ratio that matches the photos, or use Masonry, which sizes each cell to the photo.
Can I reorder the pictures? Yes. Drag the handle on any thumbnail to move it, and it lands in that position in the collage.
Is anything uploaded? No. The collage is drawn on a canvas inside your browser. Nothing is sent anywhere, and closing the tab removes everything.
