Mosaic Collage Maker vs Posterino
Two Mac collage apps with different aims. Here is how they differ, and who each suits.
The short version
Posterino is a long-established Mac app for designing posters and collages from templates and layouts. Mosaic Collage Maker is built for one job: filling many photobook pages with photos automatically, at the exact page size your printer specifies, with no fixed grid.
If you want to design a single poster from a template by hand, Posterino is a good fit. If you have hundreds of photos and a photobook service to fill, Mosaic Collage Maker is aimed at that.

Choose Mosaic Collage Maker if…
- You are making a photobook and want every photo placed across many pages without dragging them in one at a time.
- Your printer specifies an unusual page size in millimetres.
- You would rather not have frames poured into a repeating template.
- You want a one-off purchase that works offline with no account.
Choose something else if…
- You want to design a single poster from a library of designed templates.
- You want a full drawing or desktop-publishing tool. Mosaic Collage Maker is deliberately focused.
Common questions
What is an alternative to Posterino for photobook pages?
Mosaic Collage Maker, a one-off-purchase app for Mac and Windows that lays out whole photobook pages automatically.
Can I still use templates?
Yes. There are no built-in fixed grids, but you can save a page design as a template and generate a whole new book from it with a different set of photos.
Will it work with my photobook service?
Yes, if you know the page size they want. The help guide lists sizes and margins tested with Photobox, Colorland, Printerpix and Mixbook. Always order a test print first.
