Choose how your photo fits the 300×300 square

The output is always exactly 300 pixels wide and 300 pixels high. The Fit setting controls what happens when the original is not square.

Cover — best default

Fills the square without distortion and crops equal areas from the long edges.

Contain — keep everything

Keeps the whole image visible and fills unused space with the selected background.

Stretch — use with care

Forces the image into a square and can make faces, logos, or text look wider or taller.

Start with the largest clear original

Reducing a large image usually stays sharp. Enlarging an image below 300×300 cannot create missing detail, so the result may look soft.

Upload the image, leave Width and Height at 300, choose Cover, Contain, or Stretch, then select Resize Image and download the result.

How do I make a 300×300 image without stretching it?

Use Cover to fill the square with a centered crop, or Contain to keep the entire image with padding. Avoid Stretch when proportions matter.

Yes. The result canvas is exactly 300 pixels wide and 300 pixels high. The preview also reports the output dimensions before download.

Can I make a 300×300 JPG or PNG?

Yes. Choose Auto to keep a supported input format, or select JPG, PNG, or WebP under Output format.
