  • Choose to fill the space with cropping, or show the whole picture with bars.
  • Press Resize and download.

Sizes in the list

  • Instagram: 1080 x 1080, 1080 x 1350 and 1080 x 1920.
  • YouTube: thumbnail 1280 x 720, banner 2560 x 1440.
  • Facebook, X, LinkedIn, Pinterest and WhatsApp sizes as well.

Crop or add bars?

Fill the space gives a full picture but cuts the edges. Show the whole picture keeps everything and adds bars in a colour you choose.

Check the platform

Apps change their favourite sizes now and then. Treat these as good defaults and check the platform's help page for special cases.
