How to make a collage

  • Open Collage Maker and add your pictures.
  • Move pictures up or down to set the order.
  • Choose a grid, side by side or stacked layout.
  • Choose the space between pictures, the background colour and JPG or PNG, then press Make collage.

Tips

  • Use pictures with a similar shape for a tidy grid.
  • A small white gap looks clean. A bigger dark gap looks bold.
  • Use PNG if you will edit the collage again, JPG for sharing.

Good to know

Pictures are cropped to fill their space in a grid. Side by side and stacked layouts keep each full picture.
