Tips for better results

  • Keep the aspect-ratio lock on unless you deliberately want a stretched image.
  • Enlarging cannot invent detail — going above the original size makes images softer, never sharper.
  • Check the required dimensions before you start; many application forms specify exact pixel sizes for photos.

Examples

Making a profile picture fit an exact requirement

Enter the required width and height with the ratio locked, resize, then compress if the platform also caps the file size.
