A Facebook square post is an image displayed at a 1:1 ratio in the News Feed, with a recommended size of 1080×1080px. It is used for carousel ad slides, Marketplace product photos, and card-style infographics, filling the full mobile screen width for strong visual impact. Since it matches the Instagram square spec, one image works on both platforms. This tool crops your image to 1080×1080px and saves it as JPG instantly.

No. The 1:1 ratio displays without cropping in the feed. On mobile, it fills the full screen width, giving it more visual weight than landscape images.
Yes, 1080×1080px (1:1) is the standard for Facebook Marketplace listings. Use a clean background so the product stands out clearly.
Square (1:1) images generally earn higher click-through on mobile because they occupy more screen area. Landscape 1200×630px works better for link-share previews.
