Gridley

In the eventuality that you want to scramble your screenshots, mockups or other images you accumulated throughout the year, then the good news is that you do not have to go for advanced graphic editors for this simple task.

Gridley is a lightweight utility that provides you with a quick way to generate one image from multiple ones even if you do not have any experience with similar apps.

The application does not require installation or configuration, so you can start using it as soon as you download it to your computer. The program comes with a modern interface that is split into two sections, namely the settings and the preview area.

You can get started by dragging and dropping the images over the dedicated area. As far as the Settings are concerned, you can specify various parameters for your collage, such as the number of columns, padding or whether you prefer to maintain the aspect ratio.

You can add a border and specify if you want to embed the images with their original height/width or a custom value between 100 and 4000 px. Lastly, you can define some preferences for the new picture, meaning the file format, background color and the final grid width.

According to the developer, you can combine as many as 15 photos at once with the application. Then again, you should bear in mind that the dimensions and sizes of the images you intend to use are going to affect the speed and performance of the tool.

Regardless of whether you are just mixing up mockups for fun, want to create a wallpaper with the footage you took during a trip in nature or need photo thumbnail sheets for a school or work project,  Gridley could come in handy.
