What Is Resize Image by Percentage?

The Resize Image by Percentage tool scales a picture by a single factor you choose, from a 1% thumbnail all the way to a 500% enlargement. Because one percentage drives both dimensions, the original proportions are never distorted. It is the quickest way to make a batch of images a consistent relative size.

Who Uses the Resize Image by Percentage?

Photographers, product photographers and web developers use it to make thumbnails, generate a smaller set of a large export, or blow an image up for a large-format print.

How to Use the Resize Image by Percentage

  1. Drop in the image you want to scale.
  2. Enter a percentage between 1 and 500, or tap a 10%, 25%, 50%, 75%, 150% or 200% shortcut.
  3. Press Resize Image and download the scaled copy, then compare it against the original.
