How to Resize an Image to 1080×1080 (Free, Exact Pixels)

1080×1080 is the size Instagram wants for a feed post. Here's how to hit it exactly, for free, without stretching your photo.

1080×1080 pixels is the square Instagram serves at full quality, and it is the number most social schedulers ask for. Getting there is not hard, but two things go wrong constantly: people stretch the image by setting both numbers independently, and people upload something far smaller than 1080 and wonder why it looks soft. Here is how to do it properly in about twenty seconds.

Resize and crop are not the same thing

Resizing changes how many pixels an image has. Cropping changes which part of the image you keep. If your photo is already square, resizing to 1080×1080 is all you need. If it is a rectangle, resizing it straight to a square will squash it — you want to crop it square first, then resize. The cropper has a one-tap Square (1:1) ratio for exactly this.

How to resize to 1080×1080

Open the resizer, drop your photo in, and type 1080 into the width. With the aspect ratio locked, the height follows automatically — if your image is square, it lands on 1080 too. If you need both numbers forced to 1080 regardless of shape, unlock the ratio first, though be aware that is the setting that stretches things. Download when the preview looks right.

Start bigger than 1080, not smaller

Making an image smaller keeps it crisp — you are throwing away pixels you did not need. Making it bigger does not add detail, it just spreads the pixels you have, which is what makes an enlarged photo look soft. If your original is only 600px wide, resizing up to 1080 will look worse, not better. Run it through the AI upscaler instead, which generates genuine new detail.
