How it works

Use Social Image Resizer in three steps

  1. 1

    Add an image or design.

  2. 2

    Choose a common preset or enter custom dimensions.

  3. 3

    Select Cover to fill the frame or Contain to keep the full design, then export.

Design for the crop, not only the canvas

A vertical story and a square post show different parts of the same image. Keep faces, titles and logos away from the extreme edges so they remain visible when the layout changes.

Platform interfaces can cover parts of a vertical image with captions and controls. Leave comfortable empty space around essential text.

Presets are a starting point

Platforms can update recommendations. The tool uses widely used creative dimensions, but you should confirm a client or platform requirement when an exact specification matters.
