How it works
Add your photos
Choose between 2 and 20 images; drag the rows to arrange them in reading order.
Set columns and cells
Pick 1 to 6 columns, the cell size in pixels and the background color.
Download the mosaic
Save the single PNG wall and share or print it.
One wall from many photos
Holidays, weddings, portfolios and product ranges all produce piles of pictures that are awkward to share one by one. A mosaic wall tiles them into a single even grid, left to right and top to bottom, so the whole set reads at a glance.
Every photo is fitted inside its own square cell without stretching, with the background color filling any letterbox gaps. Raise the cell size for crisp large prints or lower it for a compact collage that is easy to send.
Arrange, then tile
The order of the list is the order of the wall: the first photo lands top-left and the rest follow row by row. Drag rows on a computer, or use the arrow buttons on touch screens, until the sequence tells your story.
Columns run from a single vertical strip up to six across. Two or three columns suit portraits and storytelling, while five or six columns turn big collections into a dense contact sheet you can scan quickly.
Family photos stay in the family
Collage websites are hungry for your pictures: uploads train their models, thumbnails linger in caches, and shared links outlive the occasion. Building the wall inside your browser keeps every face, home interior and geotagged memory exactly where it started.
The tiling, fitting and PNG encoding all happen on your device with no account and no gallery. Arrange pictures of children, documents or work prototypes with the same ease as landscapes, knowing none of them cross the network.
Questions
Are my photos uploaded to build the mosaic?
No. Your images are opened and tiled inside your browser. They never leave your device.
How many photos can I combine?
From 2 to 20 images per wall. Each can be up to 100 MB, in JPG, PNG, WebP, GIF, BMP, AVIF, HEIC or HEIF.
Why did the cell size shrink?
Browsers cap images at 4096 pixels per side. If your columns times cell size would exceed that, the cells are scaled down proportionally and the note tells you.
Is it free?
Yes. Free to use, with no sign-up, no watermark and no daily limits.
