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.

Best poster or collage making software

This app keeps getting better, and is now by far the best poster maker. It enables you to easily and intuitively set poster size, dpi, photo borders and poster margins. It automagically makes an attractive tiled poster of any number of images, and supports sorting the photos in a variety of ways, including by filename, so you can establish whatever sequence you want in your photo management software (like Lightroom) and maintain that sequence in Posterino. This is very important in large posters with hundreds of photos. Finally, it is very easy and intuitive to pan/zoom individual photos within the Posterino defined frames.
I've done many posters as gifts for friends and family over the last 18 years using several applications. I recently made a poster image for printing on a 50x60 inch blanket which my mother loved! The poster making experience was a true delight and I was able to make a great poster quickly, beating the midnight deadline for 50% off of the blanket!

Amazing App Support

I am a frequent user of Posterino and enjoy it. Recently I encountered a problem with it and sent info regarding the issue to the Support email. I was amazed to get an immediate response with several questions regarding the issue which I answered right away. Within a couple of days I was provided with a BETA version of the App to test - it resolved the issue! I have never gotten this type of response to an issue from any other app support. Fantastic customer support!!

I don't always need collages, but when I do...

Posterino is excellent at what it does. Super fast collages. You'll get a wealth of templates and the app is great even for preparing single images for display.

Christoph has been very quick to answer to support requests and to suggestions for new features.

I have not come across anything better and after years of usage Postering for collages, It remains my go-to software for display of multple images whether for print or on screen.

Developer Response ,
