What is the short answer?
Add the image, choose Exact pixels, enter equal width and height values, select Fit, choose a background color and download the square result.
Why does Fit avoid cropping?
Fit scales the source proportionally until both sides remain inside the square. A portrait leaves space on the left and right, while a landscape leaves space above and below. No part of the original is cut away or stretched.
What square size should you choose?
Follow the destination's current requirement. Use equal width and height values such as 1080 by 1080 when a general social image needs a practical square canvas. A profile system may display the uploaded square inside a circle, so leave room around faces and logos.
Which background color works best?
Choose a neutral color or sample the general mood of the photo. White works for many product listings, while a dark background can suit screenshots or artwork. Strong contrasting bars make the padding look accidental.
Will the image lose quality?
Downsizing can reduce fine detail, while enlarging cannot create new detail. Start from the highest-resolution source available and avoid repeated exports. PNG suits logos and interface graphics; JPG is usually smaller for photographs.
What should you check after export?
Open the result and confirm its width and height are identical. Preview it at thumbnail size because wide padding that feels balanced on a large screen may make the subject too small in an avatar or product grid.
