Posterino is all about flexibility. A template is a starting point and not a rigid grid of images. Wether you like to present 1 or 1000 images. Wether you go postcard or poster size. Layouts are applied automatically, making a simple Drag & Drop gesture all you need to create a collage of your images. Or go pro and apply fine grained control over layout, style and appearance.

These characteristics are described by its users as the “magic” of Posterino.

The new Square-Grid layout is build in the same spirit. It bridges the gap between a completely automatic and a manual layout method. Thereby providing the lightning fast first sketch of a collage and the flexibility of tweaking every tiny aspect of the layout. And it does this in a fun and enjoyable way.


Design collages in minutes. The innovative interface enables a large degree of customization through a variety of templates featuring grid, tile, square-grid, circular and random layouts. Adjust frames, filters and backgrounds to your liking. The result is a beautiful collage ready to be printed and displayed.

Collages instantly!

I have used this app for over 5 years, and with each upgrade it just keeps getting better and better. You can literally drop your images onto a template and it instantly creates a collage. If you want to tweak it, you can just hit the "re-sort" button, and your images will be moved into new spots...keep doing that until you are satisfied,and then export your finished creation at the touch of a button...As smoot as an app can be, I love it.

Brilliant piece of software!

If you are looking for a collage app to make posters, etc., look no further. Posterino has been around for a long time and just continually gets better and better. Also, the dev is active and responsive, which is always a good sign.
This is an app that I don't use all the time, but when I do need its services, I have found none better!

Keeps getting better

I've had this from the first version. I've used it a lot for making large prints for clients who want a collage of staff or events. It just works so easily and it makes ceating this kind of thing super easy.

I've used it also for creating prints of road trips. People who study the apps just love how clean the output looks.

Very responsive developer too.
