Hello! I'm giving a very short tutorial on how to make an आइकन square (since I often saw many un-square icons). आप don't need Photoshop या GIMP या 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 आइकन या any picture आप want to make square.
3. Click on the "Crop" आइकन on the चोटी, शीर्ष left of the panel. Choose "output size" on the "Constraint" dropdown. Enter 200 x 200 या whatever square size आप want.
4. Drag the माउस over your picture. Hit Enter.
5. Don't forget to save your square picture!
