About the Instagram Post Resizer

The classic Instagram feed post is a 1080×1080 pixel square (1:1). This tool scales your image to fill that square and center-crops the overflow so nothing is stretched, all in your browser. Uploading at 1080×1080 gives Instagram a full-resolution image to work from, which keeps your post looking crisp instead of soft after the app re-compresses it.

Frequently asked questions

What size is an Instagram post?

The square feed post is 1080×1080 pixels (1:1). Instagram supports up to 1080 px wide, so 1080×1080 is the sharpest square you can upload. This tool outputs exactly that.

Will my photo be stretched to fit the square?

No — it is scaled to fill the 1080×1080 square and center-cropped, so the proportions stay correct. Keep your subject centered for the best crop.
