One ad in. Four ready-to-upload sizes out.

AdResize is a free tool for anyone who makes Facebook and Instagram ad creatives. It turns the one image you already have into every size your campaign needs, so you never rebuild the same ad by hand.

  • The problem

    You design one ad, usually a square. Facebook and Instagram then show it in the feed, Stories, Reels and link previews, and each of those is a different shape. Upload just the one image and Ads Manager crops it for you, which is how headlines, prices and logos get cut off.

  • The usual fix

    Open Canva or Photoshop and rebuild the same ad three more times, once per size. It is slow, it is dull, and it has to be done again for every new creative you want to test.

  • What AdResize does

    Upload the ad once. AdResize makes the square, feed, Stories and Reels, and landscape versions in a few seconds, at the exact pixel sizes Meta asks for. Nothing is stretched, and you choose how the extra space is filled.
