How to resize an image

  1. Upload the image you want to resize.
  2. Enter the new width and height, or a percentage.
  3. Keep the aspect ratio locked to avoid stretching.
  4. Download the resized image.

Why size matters

Social sites, forms, and profile pictures often ask for a set size. A photo that is too big gets cut off or rejected. Resizing gives you the right dimensions so the image fits the space without looking squashed.

Keep it looking right

Lock the ratio so the picture does not stretch out of shape. Making an image smaller keeps it crisp, while enlarging a lot can soften it. Start from the largest version you have for the best result.
