Hello! I'm giving a very short tutorial on how to make an ikon square (since I often saw many un-square icons). anda don't need Photoshop atau GIMP atau heavy picture editors. Here I'm using link
1. Click "Editor". Here you'll see a Photoshop-like layout.
2. Click "Open image from computer". Select your ikon atau any picture anda want to make square.
3. Click on the "Crop" ikon on the bahagian, atas left of the panel. Choose "output size" on the "Constraint" dropdown. Enter 200 x 200 atau whatever square size anda want.
4. Drag the tetikus over your picture. Hit Enter.
5. Don't forget to save your square picture!
