Make Grid Collages from Images

Do you have tens or hundreds of images, and you want to create a collage with all these images in a grid? It is very easy to do!

There are two steps: Resizing images and Arranging images into a grid. We will do it using a free photo editor Photopea.com.

Resize images

In Photopea, press File - Automate - Resize Images. Click "Source Images" and select all the images from your computer. Set a new size (e.g. a maximum height of 200 pixels) and click "Resize Images". A ZIP file with all resized images will be downloaded to your computer. Just unzip it into a folder, to use later.

Arrange images into a grid

In Photopea, press File - New, and set the Width and the Height of the new document (e.g. 2000 x 2000 pixels). Now, press File - Open and Place, and select all small images from the previous step. All of them will be placed into your document, one on top of another.

Select them all (by drawing a rectangle around them with the Move tool, or by pressing Ctrl+Alt+A) and click the Align to a grid button (at the top). Here, you can set the number of columns, set the gaps, etc. Once you set it, press "Auto-Align".

Now, just save your work by pressing File - Export As - JPG - Save, and it is done! :)
