Frequently asked questions

It scales the canvas to 1080x1080 pixels, the optimal resolution for crisp, standard square Instagram posts.

You can choose to either crop the edges to fill the square, or shrink it to fit and add a custom background color to fill the gaps.

No, this utility is strictly for static image posts, not video content or 9:16 story formats.

Uploading at the exact recommended dimensions minimizes how aggressively Instagram applies its own compression algorithms.

Only if you select the "Fit" option for a non-square image; otherwise, it crops to the edge.
